piRNA sequences are complimentary to
A) mRNA from a transposable element.
B) another RNA within the piRISC.
C) the Crispr gene.
D) bacteriophage DNA.

Question

Quizplus · Accepted Answer

piRNAs are short RNA molecules that play a role in controlling transposable elements in eukaryotic genomes. They function by binding to Piwi proteins to form the piRNA-induced silencing complex (piRISC), which can recognize and degrade mRNA transcripts from transposable elements based on complementarity between the piRNA and the mRNA sequence. Therefore, piRNA sequences are complementary to mRNA from a transposable element (Choice A). They are not complementary to other RNA within the piRISC (Choice B), the Crispr gene (Choice C), or bacteriophage DNA (Choice D).
