mRNA brings the code of DNA to the ribosome where it is used to construct a protein

Detailed explanation-1: -The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.
Detailed explanation-2: -mRNA or Messenger RNA serves as an intermediary between DNA and directs the synthesis of proteins during translation. rRNA or Ribosomal RNA ensures that the mRNA, tRNA, and the ribosomes are properly aligned during protein synthesis.
Detailed explanation-3: -mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes. Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide. Thus mRNA carries a “message” from the nucleus to the cytoplasm.
Detailed explanation-4: -mRNA provides a genetic blueprint for the protein.
