WebA point mutation is where you change one base in the DNA to another. A missense mutation occurs when that point mutation causes a different amino acid to be placed from that codon. Because multiple codons code for the same amino acid, not all point mutations will cause a missense mutation. ( 9 votes) Upvote esther6894719 3 years ago
