What is the role of mRNA in protein synthesis?
The role of mRNA (messenger RNA) in protein synthesis is to carry the genetic information from the DNA in the nucleus of a cell to the ribosomes in the cytoplasm. During transcription, the DNA sequence is transcribed into an mRNA molecule, which then undergoes a series of modifications and processing steps to become mature mRNA. This mature mRNA contains a sequence of nucleotides, called codons, that specify the sequence of amino acids in a protein. The ribosomes read the mRNA codons and match them with the corresponding tRNA (transfer RNA) molecules, which carry the appropriate amino acids to the ribosome. The ribosome then catalyzes the formation of peptide bonds between adjacent amino acids, creating a growing polypeptide chain. Ultimately, the sequence of nucleotides in the mRNA determines the sequence of amino acids in the resulting protein. Therefore, mRNA plays a critical role in protein synthesis by serving as the template for protein synthesis and conveying genetic information from the nucleus to the ribosomes.
mRNA (messenger RNA) is a type of RNA molecule that carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm during protein synthesis.
The function of mRNA in protein synthesis is to serve as a template for the ribosomes to synthesize proteins. mRNA carries the genetic information from the DNA in the nucleus to the ribosomes, which read the mRNA codons and match them with the appropriate tRNA molecules to build the protein.

If mRNA is mutated in protein synthesis, it can result in a change in the amino acid sequence of the resulting protein. This can lead to changes in the protein’s structure and function, potentially causing genetic disorders or diseases.
mRNA is synthesized during the process of transcription, which occurs in the nucleus of a cell. During transcription, the DNA sequence is transcribed into an mRNA molecule, which then undergoes a series of modifications and processing steps to become mature mRNA.
