Answer:
mRNA stands for mitochondrial ribonucleic acid. The main function of mRNA is protein synthesis in both eukaryotic and prokaryotic cells.
Explanation:
What is mRNA-:
- The DNA can not decode directly into protein. So mRNA is the molecule that carries the codes from DNA in the nucleus to the site of protein synthesis in ribosome.
- The mRNA molecules transported through the nuclear envelope of the cell.
- Each mRNA molecule encodes for one protein. In mRNA each sequence of three nitogen bases specifying the incorporation of a particular amino acid within the protein.
Functions of mRNA-:
- The primary function of mRNA is protein syntesis. It act as an intermediary molecule between DNA and the sequence of proteins.
- mRNA contains multiple regulatory regions which can control and regulate the rate of translation.
- mRNA translated on ribosomes in the cytoplasm with the help of tRNA and multiple proteins called initiation, elongation and termination factors.
