m RNA

Messenger RNA (mRNA) carries information on how to construct a protein. It is transcribed from DNA and taken to ribosomes. Ribosomes "read" mRNA to link amino acids together in a specific sequence
Messenger RNA (mRNA) is a molecule of RNA encoding a chemical "blueprint" for a protein product. mRNA is transcribed from a DNA template, and carries coding information to the sites of protein synthesis: the ribosomes

 Here, the nucleic acid polymer is translated into a polymer of amino acids: a protein. In mRNA as in DNA, genetic information is encoded in the sequence of nucleotides arranged into codons consisting of three bases each. Each codon encodes for a specific amino acid, except the stop codons that terminate protein synthesis.
