This sequence represents a single mutation. mutation #2: 5' - | ggc | gtg | gta | taa | gcg | - 3' complete these sentences about this mutated dna sequence.

This mutant DNA sequence is the result of a TRANSVERSION. Transversion, in biology, is the substitution of a purine and pyrimidine or vice versa. In this case we can see that GTA was replaced by GTC therefore Adenine (purine) for a Cytosine (pyrimidine).

The effect of this substitution in the amino acid sequence is called a nonsense mutation. Because nonsense mutation means that it has an incorrect sequence which causes shortening of protein.

The answer is observations and interpreting.

No that answer is wrong. you have written the function of mitochondria in chloroplast and function of chloroplast in mitochondria.
