Multiple Choice
RNA interference (RNAi) is a process whereby
A) RNA that has the same sequence as an introduced short piece of single stranded RNA is inhibited.
B) RNA is degraded (or interfered with) on a systemic level by any non-specific causal agent.
C) RNA that has the same sequence as an introduced short piece of double stranded RNA is inhibited.
D) a rogue sequence of RNA is formed by an intron creating a new ORF which inhibits (interferes with) general RNA synthesis by creating excess transcripts.
E) a short RNA sequence binds to ribosomes, preventing other transcripts from being processed and thus interfering with RNA processing.
