This segment of DNA mutates at a rate of one base pair per 33 million years. Species A mtDNA sequence with TACAAGATAC and Species B mtDNA sequence with TACGCGTAAC. Based on these DNA sequences, 66 million years ago, the two species diverge from a common ancestor. Thus, option C is correct.
Mutation can be defined as the change in nucleotide sequence of the genome of a living organism either DNA or RNA due to various environmental factor like UV light and DNA replication error.
Many mutations are neutral and some are harmful as well as helpful in some manner. It can be inherited from parents to a child. Some other causative agents are chemicals or excessive radiation.
There are four types of mutation gene mutation, somatic mutation, germinal mutation and chromosomal mutation.
In case of gene mutation, a mutation occur in DNA occurs leads to change in one or more nitrogenous bases takes ultimately produce an effect on proteins are product and its expression.
