For protein translation to begin, the codon AUG must be identified.
PROTEIN SYNTHESIS:
Protein synthesis is the process whereby living organisms synthesize proteins using the information stored in their DNA. Protein synthesis involves transcription and translation. Transcription occurs in the nucleus where DNA is used as a template to synthesize mRNA. Translation occurs in the ribosome where mRNA transcript is used to synthesize amino acid sequence. During translation, mRNA codons are read and binded to by the anticodons of a tRNA molecule.However, for translation to begin, a specific mRNA codon called START CODON with the sequence: AUG must be identified first.

In 1998, paleoanthropologist Rick Potts published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Which would most likely be found in his paper? a review of modern human anatomical structure evidence of changing environmental conditions, with references the reasons competing hypotheses are wrong his opinion of what will happen to the survival of the human race
Answer:
Dr. Potts used environmental data to support environmental hypotheses capable of explaining human evolution
Explanation:
In this paper, the author stated that environmental factors have been fundamental for the emergence of adaptive traits during human evolution. In consequence, Dr. Potts explained how particular environmental factors and habitats might have shaped human evolution. For example, it has been hypothesized that dry savanna vegetation might have been a key environmental factor associated to the emergence of human traits including, among others, bipedality, making of tools from stones, the development of human brains, etc. In order to prove this hypothesis, the author recorded environmental data from different regions in Africa (Olorgesailie, Olduvai, Turkana, Zhoukoudian, etc), where it is believed that first hominids evolved about 6-8 million years ago.

binomial nomenclature is a two word system for naming organisms by using the genus and species .
Explanation:
As the name indicates" bi" two and "nomial" name therefore
binomial nomenclature is a two word system for naming organisms by using the genus and species . it uses both the genus and species of the organism.
The binomial nomenclature consists of a two word system for naming organisms by using the genus and species.
What is the purpose of binomial nomenclature?Binomial nomenclature is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages.
Binomial nomenclature is a binomial system of naming a species. A binomial name is comprised of two parts. They are (1) the generic name (genus name) and (2) the specific name (or specific epithet, in botanical nomenclature). It is often in a Latinized form.
Every recognized species on earth (at least in theory) is given a two-part scientific name. This system is called "binomial nomenclature." These names are important because they allow people throughout the world to communicate unambiguously about animal species.

Explain why mutations that replace S/T/N residues with A/L/W residues in the N-terminal region of transmembrane proteins that function as cell surface receptors could significantly disrupt that utility of these proteins as receptors.
Answer:
Serine (S), Threonine (T) and Asparagine (N) are primary binding sites of carbohydrates, and thereby they are required to form glycoproteins (i.e., glycosylation products)
Explanation:
A transmembrane protein (TP) is a particular type of protein that crosses the cell membrane in order to enable the movement of ions and molecules. Transmembrane proteins are divided into alpha-helical and beta-barrel proteins. The N-terminal region of transmembrane glycoproteins can be required for N-linked glycosylation, which is an enzymatic mechanism capable of attaching oligosaccharides to proteins in order to form glycoproteins (glycans). N-linked glycosylation is a posttranslational protein modification that has distinct functions depending on the cell type and the protein region involved in such modification. For example, in the surface of immune cells, the N-linked glycans are capable of dictating the migration pattern of these cells.

How does increasing the distance between charged objects affect the electric force between them?
O The electric force increases because the distance has an indirect relationship to the force.
The electric force increases because the distance has a direct relationship to the force.
O The electric force decreases because the distance has an indirect relationship to the force.
O The electric force decreases because the distance has a direct relationship to the force.
Answer:
C. The electric force decreases because the distance has an indirect relationship to the force.
Explanation:
The electric force decreases because the distance has an indirect relationship to the force. Therefore, the correct statement is option C.
What happens when the distance between two charged items grows?As the distance between two charged items grows, the electric force between them diminishes. Because of the inverse square law, which states that the force of attraction or repulsion between two charged objects diminishes as the square of the distance between them rises, this is the case.
The force exerted by two charged objects will be decreased to one-fourth of its initial strength if the distance between them doubles. Similar to this, if the distance is quadrupled, the force loses 90 percent of its initial power. As a result, the electric force between charged objects lessens with increasing distance.
The farther the distance between charged objects, the weaker the electric force between them becomes due to the decrease in the strength of the electric field. This relationship follows an inverse square law.
Therefore, electric force decreases because the distance has an indirect relationship to the force.

42) When yellow-seeded and green-seeded pea plants are crossed, all the offspring are yellow-seeded. When the F1 yellow-seeded plants are crossed to green-seeded plants, what is the hypothesized genetic ratio
Answer:
See the answer below
Explanation:
From the illustration, the yellow color trait is dominant over the green trait.
Assuming that yellow seededness is represented by the allele Y and green seededness by the alleles y. Y is dominant over y, hence a yellow seeded plant would be either YY or Yy while a green seeded plant would be yy.
For a cross between a yellow seeded plant and a green seeded plant to yield all yellow seeded offspring, it means that the parents are YY and yy.
(yellow)YY x (green) yy
F1 progeny: All Yy (yellow)
Now, Yy is crossed with green-seeded plant, yy.
Yy x yy
Yy Yy yy yy
Hypothesized Genotypic ratio
Yy = 1/2
yy = 1/2
Hypothesized Phenotypic ratio
Yellow seeded = 1/2
green seeded = 1/2

Your mom has started complaining to you about her varicose veins and is thinking about surgery. What true information could you tell about varicose veins?
Answer:
One very true and essential information to know about varicose veins is that there is often re-occurrence following after surgery.
Explanation:
Varicose veins are a group of large, benign, twisted, and superficial veins on the skin surface. They may come with no side effect in some sufferer (asides from the physical appearance), and can cause chronic pain and discomfort in others, usually pointing to an underlying circulatory problem. Varicose veins are caused by damaged or weak valves in the veins, and complications like bleeding might occur. Some people with the risk of developing this disease are obese people, people with genetic tendencies, and usually pregnant women. Treatment methods includes compression stocking, a lifestyle change, and some medical procedures like surgery. After surgery, there is usually re-occurrence.
A mosquito somatic cell contains 6 chromosomes. This means that ____ different combinations of chromosomes are possible in the mosquito’s gametes as a result of the random alignment of chromosomes during meiosis.
Answer:
8
Explanation:
The law of independent assortment of genes as proposed by Gregor Mendel states that the alleles of a gene will separate into gametes independently of the alleles of another. This means that during the metaphase stage of meiosis I, line up randomly at the metaphase plate of the cell in order to be separated independently.
According to the question, a mosquito has 6 chromosomes in its somatic cells. This means that 2n (diploid) = 6 Chromosomes. Hence, after meiosis, its gametes (n) will contain 3 chromosomes each. To find the number of different combinations of chromosomes possible in the mosquito’s gametes, we use 2^n where n represents the number of haploid chromosomes.
Hence, if 3 chromosomes are possible in a mosquito's gametes, 2^3 = 8 different combinations of chromosomes are possible in the gametes as a result of random orientation during the metaphase of meiosis.

What makes ribosomal RNA useful as a molecular clock? (2 points) A large portion of the DNA ring is not vital to structure or function, allowing it to accumulate neutral mutations. Its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. A slow mutation rate makes it useful for determining evolutionary relationships between ancient species. It is only found in select organisms, making it easier to compare relationships between species that have it.
Answer:
The correct statement is that a slow mutation rate makes it useful for determining evolutionary relationships between ancient species.
Explanation:
The rRNA or ribosomal RNA has an application as a molecular clock because of many factors. It exhibits a very slow mutation rate, that is, around one million years because of which it stays highly conserved in all the organisms. In the ribosomal RNAs of two organisms, the degree of mutations can be associated directly with the time they were originated in the past.
In supplementation, it possesses essential biological function because of which it can be witnessed in almost all the species.

Why does deleting just one nucleotide cause a dramatic change in the amino acid sequence produced by translation
Answer:
The deletion changes the genetic code.
Explanation:
The sequence of nucleotides determines the order of amino acids in a protein, the order of amino acids determines the shape and the shape determines the function. A very good example of one misplaced nucleotide having tremendous effects is sickle cell disease, where thymine is replaced with adenine(CAC instead of CTC). It means that glutamic acid is replaced with valine. This alters the shape of the protein(Beta chain of hemoglobin). So the red blood cells are deformed and carry a lot less oxygen leading to a lot of symptoms just because of one misplaced letter.
Is cloning an organism the same as cloning a gene
Answer:no. In nature, some plants and single-celled organisms, such as bacteria, produce genetically identical offspring through a process called asexual reproduction. In asexual reproduction, a new individual is generated from a copy of a single cell from the parent organism.
Natural clones, also known as identical twins, occur in humans and other mammals. These twins are produced when a fertilized egg splits, creating two or more embryos that carry almost identical DNA. Identical twins have nearly the same genetic makeup as each other, but they are genetically different from either parent
Gene cloning produces copies of genes or segments of DNA. Reproductive cloning produces copies of whole animals. Therapeutic cloning produces embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues.
Gene cloning, also known as DNA cloning, is a very different process from reproductive and therapeutic cloning. Reproductive and therapeutic cloning share many of the same techniques, but are done for different purposes.
