Answer to Question #93379 in Biochemistry for Kylie

Question

Write down the four major types of RNA found in cells.

Answer 1

There are 4 types of RNA, each encoded by its own type of gene:

• mRNA - Messenger RNA: Encodes amino acid sequence of a polypeptide.
• tRNA - Transfer RNA: Brings amino acids to ribosomes during translation.
• rRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.
• snRNA - Small nuclear RNA: With proteins, forms complexes that are used in RNA processing in eukaryotes. (Not found in prokaryotes.)
