Substitution, missense mutation
Explanation:
Mutation is a change in the DNA sequence that can subsequently alter the genetic message.
Substitution mutations occurs when a base is replaced with another different base.
A good example is the one given in the question where the third A in the sequence ACAAAC is replaced by a T.
If this kind of mutation occurs in a protein-coding gene, it will be classified as a frameshift mutation.
Missense mutation is caused when there is a change in a single nucleotide that results to the coding of a different Amino acid
Cells have different uses and functions. There must be differentiation/diversity between cells to form a functional organism.
