Answer:

The correct answer will be option-D.

Explanation:

In eukaryotes, the process of transcription takes place inside the nucleus whereas translation takes place in the cytosol. So, mRNA has to export to the cytosol from the nucleus.

Before export, the post-transcriptional modification takes place like 5' capping, 3' tailing and splicing mechanism.

The capping is done at 5' end by adding modified guanine (G) nucleotide which protects the mRNA from exonuclease activity and tailing is done at 3' end by adding adenine nucleotides which provides stability to the mRNA.Splicing removes the junk DNA called introns and joins the exons before export.

Thus, option-D is the correct answer.

The answer is 2 can be made by the animal's body from other substances.

Both essential and nonessential amino acids have essential roles in the organism. Nonessential amino acids got their name because they are not an essential part of the diet. The main difference between these two groups of amino acid is that essential amino acids cannot be made by the animal's body and must be ingested in the diet unlike the nonessential amino acid which can be made by the animal's body.

If organisms A, B, and C belong to the same class but to different orders and if organisms D, E, and F belong to the same order

zalisa [80]

Answer:

Any combination of D, E and F

Explanation:

Since A, B, and C belong to different orders, and D, E and F belong to the same order, the latter are more closely related and thus are expected to show a greater degree of structural homology. They are closer to their common ancestor than A, B and C.
