Genetic Mutations
Match type of DNA mutation on the left with the definition on the right.
insertion
deletion
substitution
a base is removed
one base is switched for another
a base is added
Match type mutation on the left with the definition on the right.
frameshift
missense
nonsense
silent mutation
changes the codon to a STOP codon
the genetic code shifts, resulting in a change of amino acids during translation
has no effect on the amino acid produced during translation
changes a single amino acid that will be produced during translation.
Compare the mutated DNA sequence to the original. Identify the mutation as either an insertion, deletion, or substitution, and whether it is a frameshift, missense, nonsense, or silent mutation.
