alternative splicing
answer
mRNA processing event in which some exons are removed or joined in various combinations. By this process, one gene can specify two or more slightly different proteins.
question
anticodon
answer
Set of three nucleotide bases in a tRNA base-pairs with mRNA codon
question
base-pair substitution
answer
Type of mutation a single base-pair change.
question
codon
answer
In mRNA, a nucleotide base triplet that codes for an amino acid or stop signal during translation.
question
epistasis
answer
Interacting products of two or more gene pairs influence a trait.
question
exon
answer
Segment of RNA that is not excised during transcript processing interspersed with introns
question
genetic code
answer
code Set of sixty-four mRNA codons, each of which specifies an amino acid or stop signal in translation.
question
insertion
answer
mutation by which one or more bases are introduced into DNA.
question
intron
answer
Segment that is excised from RNA during transcript processing intervenes between exons
question
ionizing radiation
answer
Radiation with enough energy to eject electrons from atoms
