BEST RATED A+ FOR PASS
genetic recombination - CORRECT ANSWERS a process by which separate DNA
molecules are joined into a single molecule, due to such processes as crossing-over or
transposition
heteromultimer - CORRECT ANSWERS a molecular complex (such as protein)
composed of different subunits
homomultimer - CORRECT ANSWERS a molecular complex (such as protein) composed
of identical subunits
one gene: one enzyme hypothesis - CORRECT ANSWERS that a gene is a stretch of
DNA encoding one or more isoforms of a single polypeptide chain
one gene: one polypeptide hypothesis - CORRECT ANSWERS that a gene is responsible
for the production of a single polypeptide
loss-of-function - CORRECT ANSWERS recessive mutations are due to this
gain-of-function - CORRECT ANSWERS dominant mutations are due to this
silent mutations - CORRECT ANSWERS have no affect, either because the base change
does not charge the sequence or amount of protein, or because the change in protein sequence
has no affect
neutral substitutions - CORRECT ANSWERS substitutions in a protein that causes
changes in amino acids that do not affect activity
