MicroRNAs are noncoding RNAs that are ___________________ to the body of the organism. They search the __________________ in the cytoplasm for sequence complementary to that of the miRNA. When such a molecule is found, it is then targeted for __________________. RNAi is double-stranded RNA that is ____________________ to the organism. It is digested into ______________________ RNA which will then bind a complementary sequence on the mRNA of the organism, effectively protecting it from translating foreign sequences.
