| mRNA | <molecular biology> Single stranded RNA molecule that specifies the amino acid sequence of one or more polypeptide chains. This information is translated during protein synthesis when ribosomes bind to the mRNA. In prokaryotes, mRNA is normally formed by splicing a large primary transcript from a DNA sequence and protein synthesis starts while the mRNA is still being synthesised. Prokaryote mRNAs are usually very short lived (average t 1/2 is 5mins.). In contrast, in eukaryotes the primary transcripts (HnRNA) are synthesised in the nucleus and they are extensively processed to give the mRNA that is exported to the cytoplasm where protein synthesis takes place. This processing includes the addition of a 5' 5' linked 7 methyl guanylate cap at the 5' end and a sequence of adenylate groups at the 3' end, the poly A tail, as well as the removal of any introns and the splicing together of exons, only 10% of HnRNA leaves the nucleus. Eukaryote mRNAs are comparatively long lived with a half life ranging from 30minutes to 24 hours. (27 Jun 1999) |

| mRNA |
RNA molecules, usually 400 to 10,000 bases long, that serve as templates for protein synthesis (translation); in eukaryotes they have characteristic posttranscriptional modifications, the 5?cap and poly A tail. The base sequence of an mRNA transcript completely specifies the corresponding polypeptide amino acid sequence.

| mRNA |
Messenger RNA (mRNA) is RNA that carries information from DNA to the ribosome sites of protein synthesis in the cell.mRNA runs through several steps during its usually brief existence: During transcription, an enzyme called RNA polymerase makes a copy of a gene from the DNA to mRNA as needed. In prokaryotes, no further processing of mRNA occurs (except in rare cases), and often translation of the mRNA into protein occurs even while transcription is going on. ...

| mRNA |
The RNA transcript of a protein-encoding gene. The information encoded in the mRNA molecule is translated into a polypeptide of specific amino acid sequence by the ribosomes. In eukaryotes, mRNAs transfer genetic information from the DNA to ribosomes, where it is translated into protein.

| mRNA |
Template for protein synthesis. Each set of three bases in mRNA specifies a certain amino acid in a long chain of amino acids that make up a protein. The sequence of a strand of mRNA is based on the sequence of a complementary strand of DNA. Nucleotide A piece of DNA or RNA that contains one base, one phosphate group, and one sugar unit. Thousands of nucleotides joined end-to-tail make a molecule of DNA or RNA.
