Question

This table shows the codons found in messenger RNA. Using this information, what sequence of nucleotides in the
template strand of DNA could code for the polypeptide sequence Val-Asp-Ser?
O GUU-GAU-AGC
O CAA-CTA-TCG
O GTT-GAT-AGC
OCAA-CUA-UCG

Answer 1

Answer:

It would be CAA-CTA-TCG

Explanation:

It is CAA-CTA-TCG because for Val we have GUU when translated into DNA it is CAA. For Asp we have GAU which is translated into CTA. For Ser we have AGC which is translated into TCG.

I will do a follow up after I finish the test if this is completely right. I believe that it is. I have also included a file of a chart for the codons and it is easier and better that the one you showed.

Answer 2

The sequence of nucleotides in the template strand of DNA is CAA-CTA-TCG. The correct option is B.

What are codons?

A codon is a sequence of three bases of DNA or RNA. These codons are made up to code a process like protein synthesis or making a stop signal codons. Different amino acids are needed for different functions in the body.

The different bases code for different amino acids. The bases are A, T, G, C, and U. The sequence for  Val-Asp-Ser will be CAA-CTA-TCG from the chart. These sequences are made for a specific function of the body.

Thus, the correct option is  B.  CAA-CTA-TCG.
