A point mutation occurs when a single nucleotide base in the genetic code is changed during DNA replication or transcription; results from substitution mutations Silent: a nucleotide changes, but the amino acid remains the same Missense: a nucleotide changes and so does the amino acid Nonsense: a nucleotide change results in a premature stop codon
