Step-by-step explanation:
Messenger RNA (mRNA) is a single stranded RNA molecule, complementary to one of the DNA strands in a gene. The mRNA is a version of the RNA in the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made. During protein synthesis, an organelle called a ribosome moves along the mRNA, reads its sequence of bases, and uses the genetic code to translate each triplet of three bases or codon, into its corresponding amino acid.
