QUESTIONS IN IMAGES

2nd one is yes, 3rd one is CC(whatever letter you chose) or (Pro/P) Proline because I don't know what it means by 3 letter code. 4th one is no, 5th one is silent substitution

Explanation:

it changes if you change the first base pair but not the last (see amino acid/codon table), so it doesn't usually change if the last base pair is changed. Silent Substitution is a substitution that doesn't affect the amino acid due to the codon being matched to the same amino acid sequence.
