Ответ:
A a short strand of RNA that can complement and inactivate a sequence of mRNA
Option A
Explanation:
siRNA stands for small interfering RNA which has a set double-stranded RNA molecule. It is also called as silencing RNA or short interfering RNA. mRNA is a messenger molecule in the siRNA.
siRNA integrates into a protein complex known as RISC that tells the siRNA to target the RNA sequence. Then its double strands unwind into a short strand in that protein complex and remain bound to it.
It then directed by the RISC either to complement ( enhance) the mRNA molecule sequence or to degrade (inactivate) the mRNA molecule sequence.
