Answer:
Valine-Leucine-Proline-Lysine-Histidine
Explanation:
The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.
N.B: Thymine is replaced by Uracil in the mRNA
For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU
Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)
Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).
GUG specifies Valine amino acid
CUG specifies Leucine amino acid
CCU specifies Proline amino acid
AAG specifies Lysine amino acid
CAU specifies Histidine amino acid
When The central dogma generates the amino acid sequence that results from this sequence is: Valine-Leucine-Proline-Lysine-Histidine
What is a DNA sequence?
When The central dogma of biology is the process by which DNA is used to synthesize RNA and also subsequently amino acid sequence (PROTEIN). Then The processes of transcription and also translation is used in gene expression. Transcription is the process whereby the transmission encoded in a DNA molecule is useful to synthesize an mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which operates complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.
Then, N.B: Thymine is replaced by Uracil in the mRNA
After that, For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU
The translation is the second procedure of gene expression which
implicates the synthesis of an amino acid sequence from an mRNA molecule. When The mRNA is read in a group of three nucleotides called CODON. Individually codon identifies an amino acid (see attached image for genetic code)
Established on the connected genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid succession: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).
Then, GUG specifies Valine amino acid
Now, CUG specifies Leucine amino acid
After that, CCU specifies Proline amino acid
Then, AAG specifies Lysine amino acid
Now, CAU specifies Histidine amino acid

In the wild, various sperm and egg cells must navigate a complex environment to complete fertilization. There are mechanisms in place at the molecular level to guard against interspecies fertilization, even between very closely related species. Some of these mechanisms involve lock and key functions of interacting proteins. These molecules most likely regulate which type of reproductive isolation mechanism? Please explain.
Answers
Answer:
pre-zygotic reproductive isolation
Explanation:
The molecules regulate the pre-zygotic reproductive isolation mechanism.
Reproductive isolation generally refers to the variety of biological processes that sustain the formation of new species of biological organisms.
Some of these processes act to prevent fertilization or the formation of zygotes between organisms that are not of the same species (pre-zygotic mechanisms) while others ensure that the product of fertilization is invalid in case the former fails (post-zygotic mechanisms).
Some pre-zygotic mechanisms ensure that there exists no form of mating among organisms that are not of the same species due to incompatible reproductive organs, but where this fails, another pre-zygotic mechanism will act so that that the mating will not lead to fertilization and there will not be formation of zygotes.
The prevention of fertilization between organisms with compatible reproductive organs but of different species is carried out by molecules. These molecules ensure that there are locks and keys in place to prevent the fertilization of the egg by the sperm.
What substance are the bacteria (microorganisms) breaking down in the digestive system of cattle? Describe the digestion of this substance.
Answers
Answer:
The Bacteria or microorganisms are present in the rumen of cattle that aid in the digestion of cellulose and grains in the digestive system of cattle.
The process of digestion of cellulose by bacteria in cattle is anaerobic digestion and includes two steps – the production of the required enzymes and the fermentation.
In the fisrt step of production of enzyme, the microbes or bacteria are found in the first chamber of the stomach. These bacterias or microbes releases several enzymes that helps in splitting the cellulose into smaller carbs such as glucose.
These smaller carbs are the move to thrd chamber of the stomach and fermented. the required nutrients are absorbed. The digested food then finally reached at fourth chamber (acidic part), where the remained food is digested and passes to the small and large intestines.

Approximately how much methane does one cow produce per year? How does the greenhouse gas warming effect of methane compare to carbon dioxide? Describe the organisms that digest and ferment the hay inside of the cow’s stomach? How are scientists reducing the amount of methane released from cows?
Answers
Answer:
Cattle and other ruminants are significant producers of the greenhouse gas methane—contributing 37 percent of the methane emissions resulting from human activity. A single cow on average produces between 70 and 120 kg of methane per year and, worldwide, there are about 1.5 billion cattle.
While carbon dioxide is typically painted as the bad boy of greenhouse gases, methane is roughly 30 times more potent as a heat-trapping gas. ... As temperatures rise, the relative increase of methane emissions will outpace that of carbon dioxide from these sources, the researchers report.
The cow's rumen is like a large fermentation vat. More than 200 different bacteria and 20 types of protozoa help the cow to utilize fibrous feedstuffs and non-protein nitrogen sources. ... Bacteria adhere to the feed and gradually digest the fermentable material.
“You can probably reduce methane by about 20-25% by altering diet,” he says. One study by researchers at the University of California, Davis, estimated it might be possible to reduce global methane emissions from cows by 15% by changing their diet.

In Drosophila, the genes for body coloration and eye size are on different chromosomes. Normal-colored bodies are dominant to ebony-colored (very dark) bodies, and normal-sized eyes are dominant to eyelessness. Line A is true breeding for normal bodies and normal eyes, whereas line B is true breeding for ebony bodies and eyelessness. From an F 2 cross between lines A and B, 800 flies are scored. How many F 2 flies are expected to have normal body color and to be eyeless
Answers
Answer:
150.
Explanation:
150 flies are expected to have normal body color and to be eyeless in F2 generation. The reason for that population is the ratio of the species produced. The ratio of the species are 9:3:3:1. Ratio 9 refers to first parent while 1 refers to second parent and the middle 3's represent the hybrid formed. So the population of first parent is 450 and population of second parent is 50 while the population of two hybrids are 150 each.

D) to create light in a dark laboratory.
Answers
The correct answer is C) the fluorescent cells can help track the movement of cells.
Explanation:
In the last years, geneticists and scientists created animals that glow in the dark by inserting a Green Fluorescent Protein or GFP gene found in some species of jellyfish. This protein was used in animals such as rabbits, rats, and even chickens. One of the key reasons for this is that by inserting fluorescence scientists can better observe the development and movement of cells. This includes analyzing cells reproduction and growing in embryos of "glowing" animals or inserting the protein in specific cells or organs in an organism to observe how these change or move. Thus, the purpose of studying fluorescent rabbits is that "the fluorescent cells can help track the movement of cells".

Answers
Answer:
It occurred in the mother and in meiosis II stage
Explanation:
A karyotype shows that a child has Klinefelter syndrome (47,XXY) which involves a male child having an XXY chromosome in which the XX chromosome codes from the mother.
If the child is also color-blind (due to a recessive X-linked allele), despite his parents having normal color vision then the nondisjunction occurred in meiosis II because sister chromatids separate during meiosis II and the non separation is the reason for the Klinefelter syndrome.
