A DNA segment has base order CCC ATA GCT. Which copy exhibits a deletion in the first codon triplet and then a substitution mutation?

Answer 1

If we consider the DNA segment CCC ATA GCT:
1. Deletion in the first codon triplet:
If the first codon triplet CCC is deleted, we are left with ATA GCT.

2. Substitution mutation:
A substitution mutation occurs when one nucleotide is replaced by another. However, since the question does not specify which nucleotide is substituted and at which position, we cannot provide a specific answer. The substitution mutation could be any single nucleotide change within the remaining sequence ATA GCT.
