Messenger RNA (mRNA):
- mRNA was named by Jacob and Monad.
- Messenger RNA or mRNA is a single-stranded molecule of RNA.
- It helps in the process of protein synthesis through translation.
- In the cell, out of the total RNA formed, about 5-10% is mRNA.
Formation of mRNA:
- mRNA is formed during the process of transcription.
- An enzyme converts the gene into primary transcript mRNA.
- This pre-mRNA still contains introns, which are then removed by RNA splicing.
- This exon sequence forms the mature mRNA. It is then read by the ribosome and then the ribosome creates the protein.
Role of mRNA:
It helps in carrying protein information from the DNA where the mRNA sequence is read and the three base codon is translated into its corresponding amino acid.
