miRNAs, tRNAs, and rRNAs all

Question

Quizplus · Accepted Answer

miRNAs, tRNAs, and rRNAs are all types of non-coding RNA molecules that do not code for proteins. They have other functions in the cell, such as regulating gene expression (miRNAs), participating in protein synthesis (tRNAs), and forming the structure of ribosomes (rRNAs). They do not act in the nucleus as tRNAs and rRNAs are involved in protein synthesis occurs in the cytoplasm. They are not packaged with proteins to form RISC, which is a complex involved in the regulation of gene expression by miRNAs. However, miRNAs do form base pairs with mRNA molecules as part of their regulatory function.
