5 True/False questions
missense mutation → The most common type of mutation, a base-pair substitution in which the new codon makes sense in that it still codes for an amino acid.
intron → A noncoding, intervening sequence within a eukaryotic gene.
mutagen → A chemical or physical agent that interacts with DNA and causes a mutation.
mutation → A chemical or physical agent that interacts with DNA and causes a mutation.
transcription unit → The synthesis of RNA on a DNA template.
