Craig Mellow investigated RNA interference by injecting antisense and double-stranded RNAs into C. elegans. If the antisense and double-stranded RNAs were very similar, but not identical, to C. elegans mex-3, what would be the results of their experiment?
A. Virtually all the C. elegans mex-3 RNA would be degraded, so embryos from worms injected with antisense and double-stranded RNA would not be green.
B. Many different C. elegans RNAs would be degraded, so embryos from worms injected with antisense and double-stranded RNA would most likely be dead.
C. More C. elegans mex-3 mRNA would be produced by transcription, so embryos from worms injected with antisense and double-stranded RNA would be green.
D. The C. elegans mex-3 RNA would be inhibited, but not degraded, so the embryos from worms injected with antisense and double-stranded RNA would be green.
