Question

Which statement is not correct about how siRNAs and miRNAs function?

Answer 1

One statement that is not correct about how siRNAs and miRNAs function is that siRNAs always bind to the RISC protein, whereas miRNAs only bind when they are completely complementary to the target gene.

Step-by-step explanation:

One statement that is not correct about how siRNAs and miRNAs function is that siRNAs always bind to the RISC protein, whereas miRNAs only bind when they are completely complementary to the target gene.

Both siRNAs and miRNAs combine with RISC proteins to form a complex. The siRNA-RISC complex binds to mRNA and cleaves it, while the miRNA-RISC complex inhibits translation of the mRNA.

Therefore, the correct statement is that siRNAs and miRNAs both bind to RISC proteins, but they have different mechanisms of action.
