Answer #1

Answer: Option 2 (ATGGCG) is correct because in this only one nucleotide is changed during DNA replication.

Base Substitution is a gene-level mutation in which one nucleotide is substituted with another nucleotide during DNA Replication. In this, only a single nucleotide is affected in gene sequence so as a result only one codon is affected.
