Question

Quizplus · Accepted Answer

mRNA (messenger RNA) carries the genetic instructions from DNA to the ribosome, where they are used as a template to synthesize proteins. Each mRNA molecule contains a specific sequence of nucleotides that encodes the amino acid sequence of a particular polypeptide. This sequence is read in groups of three nucleotides, called codons, which specify which amino acid to add to the growing protein chain. Therefore, a molecule of mRNA contains all the codons needed to produce a particular polypeptide.
