Detailed explanation-1: -The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

Detailed explanation-2: -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-3: -mRNA carries genetic information from DNA to ribosomes. Ribosomes are the site for protein synthesis. The process of translation takes place in ribosomes.

Detailed explanation-4: -tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as “bridges, ” matching a codon in an mRNA with the amino acid it codes for.

Detailed explanation-5: -In biology, the process by which a cell makes an RNA copy of a piece of DNA. This RNA copy, called messenger RNA (mRNA), carries the genetic information needed to make proteins in a cell. It carries the information from the DNA in the nucleus of the cell to the cytoplasm, where proteins are made.
