Question

Quizplus · Accepted Answer

A nonsense variant is a single nucleotide variant (SNV) that produces a misplaced termination codon in a polypeptide chain, which results in premature protein termination and can lead to nonfunctional or truncated proteins. Missense variants change a single amino acid in the protein sequence, transposons are genetic elements that can change the position of genes within the genome, and copy number variants involve changes in the number of copies of a particular gene or DNA segment.
