Genetics Quiz on Mutations and DNA Repair

Mutations

• A mutation in a gene altering a codon, but the resulting new codon translating for the same amino acid, can be a silent mutation or a synonymous mutation. A single nucleotide polymorphism is also possible.

DNA Repair Pathways

• The post-replicative DNA repair pathway is also called specific base excision repair.
• Base excision repair is a DNA repair pathway.
• Another DNA repair pathway is nucleotide excision repair.
• Specific base excision repair is a DNA repair pathway.
