Small pieces of RNA that can regulate translation of mRNA are called
A) microRNA.
B) ribosomal RNA.
C) transfer RNA.
D) messenger RNA.

Question

Quizplus · Accepted Answer

MicroRNA are small pieces of RNA that can regulate translation of mRNA by binding to specific complementary sequences on mRNA, leading to either degradation or inhibition of translation. Ribosomal RNA is a component of the ribosome and plays a role in protein synthesis. Transfer RNA carries amino acids to the ribosome during translation. Messenger RNA carries genetic information from DNA to the ribosome for protein synthesis.
