Question

Quizplus · Accepted Answer

Ribosomal RNA (rRNA) is the RNA molecule that is linked with proteins to form the large and small subunits of ribosomes, which are cytoplasmic structures involved in protein synthesis. Transfer RNA (tRNA) carries amino acids to the ribosome during protein synthesis and messenger RNA (mRNA) carries the genetic information from DNA to the ribosome to be translated into protein. Primary mRNA transcript refers to the initial RNA molecule transcribed from DNA, which undergoes processing to become mature mRNA. Ribozymes are RNA molecules that act as enzymes, catalyzing chemical reactions. None of these other classes of RNA are directly involved in forming ribosomal subunits.
