Detailed explanation-1: -Messenger RNA (mRNA) copies the genetic instructions from DNA in the nucleus, and carries the instructions to the cytoplasm. Ribosomal RNA (rRNA) helps form ribosomes, the organelle where proteins are assembled. Transfer RNA (tRNA) brings amino acids to ribosomes, where they are joined together to form proteins.

Detailed explanation-2: -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.

Detailed explanation-3: -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-4: -RNA has three main roles in the cell: It carries the instructions from the DNA in the nucleus to the ribosomes where proteins are made in the cytoplasm of the cell. RNA picks up specific amino acids from the cytoplasm of the cell and delivers them to the ribosomes where protein synthesis takes place.

Detailed explanation-5: -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.
