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

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

Answer:

Transcription begins in the nucleus when RNA polymerase unzips a DNA molecule.

RNA nucleotides align themselves to complementary base pairs and in this manner messenger RNA is formed.

In eukaryotes must be processed before it leaves In the nucleus.

One end is modified with the addition of a cap and the other end is modified with the addition of a poly-A tail. Some sections called introns are edited out, leaving only exons remaining.

Then, the messenger RNA leaves the nucleus and enters the cytoplasm where it awaits the process of translation

Explanation:

Transcription is the process in which DNA becomes RNA. In this protein synthesis, transcription occurs in the nucleus while translation in the cytoplasm. In the first one, which is transcription, a messenger RNA is produced. In the seceond one, an amino acid sequence is produced in the ribosomes.

*Take into account there were two options missing that I added because they were the only correct answer. "In eukaryotes must be processed before it leaves In the nucleus" the only right answer is eukaryotes, because prokaryotes don't have nucleus. The other situation was in "Then, the messenger RNA leaves the nucleus and enters the cytoplasm where it awaits the process of translation" the only option given was "transcription". The right answer is "translation" because this one occurs in the cytoplasm, and transciptrion in the nucleus.

Answer: A. Since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV.

Explanation:

The statement "Since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV" best supported by the data in the graph. Hence, option A is correct.

The virus known as HIV (human immunodeficiency virus) targets the immune system of the body. HIV can cause AIDS (acquired immunodeficiency syndrome) if it is not treated. Right now, there is no efficient treatment.

Nevertheless, since 1996, there have been fewer new infections. For this reason, we can assume that if we look at the year 2000, we will observe that there was a rise in the number of HIV-positive persons but a decline in the number of HIV-positive people.

Therefore, since 2000, there has been an increase in the number of people living with HIV, but a decrease in the number of people newly infected with HIV.

Answer:

A. Reduction in soil mass proved that plants get their food from the soil.

Explanation:

Plant take their food from the soil because in soil roots are present which absorb nutrients from the surrounding environment. The nutrients present in the soil comes from the decomposition of dead bodies of plants and animals and sometimes it is provided by the farmers in the form of fertilizers. The plant food contains nitrogen, phosphorus and potassium which is required in large amount for the better growth and development of the plant.

Answer:

the misinformation effect

Explanation:

In psychology, misinformation effect occurs when false memories are formed as a result of the misleading information that was provided after the original event has taken place. This effect was studied by a psychologist named Elizabeth Loftus.

Elizabeth Loftus in her series of experiments discovered that false memories about an event can be induced by suggesting or giving wrong information about it. Hence, the involved persons remember a wrong information about the experienced event based on what they were led to remember via wrong information.

This is the case Felice, who was fed with a wrong information about the scar on her arm. This information make her have a false memory of the event i.e dog bite instead of a broken glass

The type of plate boundary that an image is expressing is known as convergent. Thus, the correct option for this question is C.

A plate boundary may be defined as a type of location where two specific plates meet. These boundaries are generally associated with numerous geological events like earthquakes.

According to the context of this question, plate boundaries govern the three-dimensional surface or zone across which there is a significant change in the velocity that may take place.

Convergent plate boundaries may be characterized as a type of plate boundary when two or more specific plates come together in such a way that they meet. At this boundary, two or more lithospheric plates collide. One plate eventually slides beneath the other.

Therefore, the type of plate boundary that an image is expressing is known as convergent. Thus, the correct option for this question is C.

Larva and pupa is present in complete metamorphosis while nymph is present instead of larva and pupa in incomplete metamorphosis.

Explanation:

Complete metamorphosis has four stages i. e. egg, larva, pupa, and adult while the incomplete metamorphosis has three stages i. e. egg, nymph, and adult. Grasshopper, dragonfly, cicada and cockroach have incomplete metamorphosis while ladybug , housefly, butterfly  and honeybee have complete metamorphosis. Both type of insects lay eggs and after hatching a baby insect comes out called larva. After sometime this larva transforms from immature to mature, this stage is known as pupa. After pupa, the insect converts into an adult which is ready for reproduction. Nymph is a stage that comes in place of larva and pupa in incomplete metamorphosis. in this stage, the insect is small in size and lack of wings but in adult stage the wings appear.

Answer:

The reaction with adenine dideoxynucleotides will run furthest in the gel

Explanation:

In dideoxy sequencing (also known as Sanger sequencing), the DNA template is used to run four different reactions in which only one class of dideoxynucleotide (ddNTP) is added. These four different ddNTPs (i.e., ddATP, ddCTP, ddTTP or ddGTP) act as terminators during DNA synthesis. Moreover, the additional factors required for DNA synthesis including standard deoxynucleotides (dNTPs), DNA polymerase and site-specific primers are added in equal volumes to prepare these four different reactions. Thus, during electrophoresis, the sizes of the DNA bands will depend on the specific ddNTP used in each reaction. In this case, the reaction containing ddATP (capable of terminating DNA synthesis at the 5' end) will run furthest in the gel.

Hello. You did not enter the answer options, but I can help you by saying that a genotype would affect the survival of a species in its natural habitat if that genotype establishes a disadvantageous characteristic for that habitat.

For example: We know that the Arctic foxes have genotypes that allow them to have a white color very advantageous for their natural habitat. That's because the white color, makes the fox camouflage itself in the environment surrounded by snow and equally white. This allows the fox to go unnoticed by possible predators, that is, its genotype favors the survival of the species. On the other hand, if the arctic fox genotype established a red color in the animal, it would affect its survival, in relation to its natural habitat. This is because it had not allowed the animal to camouflage itself in the environment, leaving it exposed to predators.

Answer:

generation 1

Explanation:

The allele frequency is a term that represents the frequency that an allele can appear in a given population. This term can help to develop conclusions about the genetic diversity that a region presents in relation to the individuals that compose it.

In relation to the question above, generation 1 had the highest frequency of having one of each allele. This is because this generation presents the maximum frequency of the dominant and recessive alleles in a coherent way, 0.60 and 0.40. However, the other generations showed a steady and progressive decrease in the recessive allele.

Answer:

The correct answer is coronary artery disease.

Explanation:

The narrowing of blockage of the coronary arteries, generally resulting due to atherosclerosis is known as coronary artery disease. Atherosclerosis also is known as the clogging or hardening of the arteries and is the accumulation of fatty deposits and cholesterol on the artery's inner walls.  

These fatty deposits of plaques can prevent the flow of the blood to the muscles of the heart by physically choking the artery or by resulting in unusual artery function and tone. In the absence of a sufficient supply of blood, the heart becomes deficient of the essential nutrients and oxygen it requires to function appropriately. This can further result in angina or chest pain.
