A ____ mutation results in the conversion of a codon specifying an amino acid to a termination codon.
A) nonsense
B) frameshift
C) chromosomal
D) missense
E) silent
Nonsense Mutation
A base-pair substitution mutation that results in an amino acid–specifying codon being changed to a termination (stop) codon; when the abnormal mRNA is translated, the resulting protein is usually shortened and nonfunctional. Compare with missense mutation.
Codon
A sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule, representing a specific amino acid.
Termination Codon
A nucleotide triplet within messenger RNA that signals the end of translation, resulting in the release of the newly synthesized protein.
