The answer is A because in a life cycle it start of in birth, then growing up, then adult then giving birth and then death. after death or birth the life cycle starts all over again. but in actuality when it gives birth that's when the life cycle is restarted. think as it's us humans. we are born. after that we grow up to be a toddler - young kid => teenager => young adult => then women gives birth => new baby is born. when new baby is born then the life cycle is restarted. but the next step after a baby's born the mom and dad get old and then death is the last step.<span />

Answer:
Base substitution mutation
Explanation:
Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:
ATCGGCTTAACG to ATCGGCTAAACG
This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.
