Question

Quizplus · Accepted Answer

The use of short, synthetic, double-stranded RNAs to intentionally destroy specific mRNAs is called RNA interference or RNAi technology, also known as knockdown technology. Knockup is not a valid term in this context. PCR (polymerase chain reaction) is a technique for amplifying DNA, but not for destroying specific mRNAs. Bioremediation is a process to clean up polluted environments using microorganisms. Nonsense refers to a mutation that results in a premature stop codon in the DNA sequence.
