When seeking to identify the gene that is responsible for a particular cellular characteristic,scientists will generate cells carrying a recessive mutation that perturbs the characteristic of interest and then try to identify or "clone" the wild-type copy of that gene through functional complementation.This type of complementation could be described as:
A)intensification of the recessive mutant trait via transferred plasmid DNA carrying the gene of interest.
B)reversal (rescue)of the recessive mutant trait via transferred plasmid DNA carrying the gene of interest.
C)identification of two different genes that both regulate the same cellular trait.
D)a biochemical phenomenon where an enzymatic process is eliminated by plasmid DNA expressing a gene of interest.
E)mutation of a gene of interest to complement an opposing biochemical pathway.

Question

Quizplus · Accepted Answer

Functional complementation involves the introduction of a wild-type copy of a gene, typically via a plasmid, to rescue the phenotype caused by a recessive mutant allele. This process results in the reversal or rescue of the recessive mutant trait.
