Definition. noun. Abbreviated form for messenger ribonucleic acid, the type of RNA that codes for the chemical blueprint for a protein (during protein synthesis). Supplement. In prokaryotes, mRNA is produced by splicing a large primary transcript from a DNA sequence.
Making the world better, one answer at a time. mRNA is messenger RNA. mRNA is transcribed from DNA, and carries coding information to the ribosomes. Here, the RNA is translated into a protein. In mRNA genetic information is encoded in the sequence of nucleotides arranged into codons.Each codon encodes for a specific amino acid, except the stop codons that terminate protein synthesis.ere, the RNA is translated into a protein.
