Genetics Quiz on Mutations

A type of mutation where an insertion or deletion of one or more nucleotides in a DNA sequence shifts the reading frame, altering the entire sequence of amino acids downstream.

A DNA repair mechanism that removes damaged or incorrect bases from DNA, primarily by using DNA glycosylases.

Mutations that change a codon but still code for the same amino acid. This leads to no change in the protein produced.

A mutation where a codon is altered, resulting in a different amino acid being incorporated into the protein.

A mutation where a codon is changed to a stop codon, prematurely terminating protein synthesis.

A type of DNA repair that fixes errors that occur during DNA replication.

DNA glycosylases are enzymes involved in removing damaged or incorrect bases from DNA. They are the first step in base excision repair.

A mutation where a codon is changed to one that codes for a stop codon, resulting in premature termination of protein synthesis.

A group of repair mechanisms that operate after DNA replication has been completed, fixing any remaining errors. These mechanisms are often less efficient than other repair mechanisms.

Mutations in a gene that do not change the amino acid sequence even though the codon may be different.
