Answer:
hydrogen gas dominated earth's first atmosphere?
Answer:
The answer is D.
Explanation:
The given situation in the question where an Adenine nucleotide is swapped for a Thymine nucleotide, which as stated are complimentary of each other just like guanine and cytosine, can cause all three types of mutations, frameshift nonsense, frameshift missense and silent because the situation is not specific to either of them. There is no information whether the change resulted in a change in the amino acid structures or not. In this case the best answer is D.
I hope this answer helps.

This question is incomplete
Explanation:
This question is incomplete but the completed question can be found in the attachment below.
During protein synthesis, a sequence of three mRNA nucleotides (called codons) correspond to specific amino acids. From the question, the change in guanosine nucleotides will change the sequence as follow
DNA: T--A--C--A--A--C--T--A--C--T--T--C--T--T--T--C--T--T--A--A--A
mRNA: A--U--G|-U--U--G|-A--U--G|-A--A--G|-A--A--A|-G--A--A|-U--U--U
Amino Acids: met -- leu -- met -- lys -- lys -- Glu -- Phe
The new amino acid sequence is represented above from the new DNA sequence.
