Answer:

mRNA → cDNA

Explanation:

Reverse transcriptase enzyme is generally used by the retrovirus for their genome replication. This enzyme was discovered by Howard tenim.

Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and  DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.

Thus, the correct answer is option (B).

Answer:

(B) mRNA → cDNA.

Explanation:

Reverse transcriptase can be defined as an enzyme, which makes cDNA (complementary DNA) by using mRNA as a template. These enzymes are also known as RNA dependent DNA synthase as they make DNA by using information present in RNA.

These enzymes are  used by eukaryotes (as telomerase) to replicate chromosome ends or telomeres, by retrotransposon, and by some viruses, such as retroviruses to replicate their genetic material.

Thus, the correct answer is option (B).

If natural selection has no foresight, how can it explain features that seem to prepare organisms for future events? for example
Nezavi [6.7K]

The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.

emmainna [20.7K]

Answer:

A. Total Vit D intake = 1150000212 IU

B. Yes he met his RDA and does not need any supplements

C. 191666702%

Explanation:

I μg = 40 IU

1 oz = 28.35 g

I g = 1000000 μg

A. Low-fat Yoplait yogurt-2 μg = 2 * 40 IU = 80 IU

Cheerios cereal-1 μg = 40 1U

Coffee with milk-07μg = 0.7 * 40 = 28 IU

Turkey sandwich on whole-wheat bread with large garden salad-0.4 g = 0.4 * 1000000 * 40 IU = 16000000 IU Grilledd pork chop. 8 oz = 28.35 * 1000000 * 40 = 1134000000 IU

mashed potato and a side of gnled mixed vegetables-1.6 μg = 1.6 * 40 = 64 IU

Total vitamin D intake = 1150000212 IU of Vit D.

B. Since his RDA is 600 IU, he met his RDA and does not need any supplements of Vit D.

C. Percentage of his RDA Vit D intake = (1150000212/600) * 100% = 191666702 %
