Question

You inherit the DNA that composes your chromosomes from your mother and your father. You have inherited a protein that STOPS the production of an enzyme, a protein, to help you digest milk. Scientists have figured out that this protein contains an amino acid that really does say STOP whenever the enzyme starts to be produced. What nitrogen bases, found in your DNA, could be arranged to produce this STOP amino acid?

A) C, G, U
B) U, A, T
C) A, T, G
D) A, T, and C

Answer 1

The answer is B

Step-by-step explanation:

Just search for the stops then look for a U, A, A. Its U A A because the T changes to an A.

Hope this helps.

Answer 2

C. A, T and G.

Step-by-step explanation:

Three stop codons of RNA are UAG, UAA, and UGA. Presence of any of these three stop codons in RNA stops the process of protein synthesis. The nitrogenous bases present in these stop codons are U, A and G. However, the corresponding bases that could be arranged into stop codon would be T, A and G. This is due to the fact that DNA does not have Uracil base, rather have thymine.
