Question

What are the $3$ types of RNA?

Answer 1

RNA:

Ribonucleic acid (RNA for short) is a nucleic acid present in all living cells that has structural similarities with DNA.

Types of RNA:

mRNA or Messenger RNA:

1. One type of RNA is found in cells.
2. mRNA molecules carry the genetic information needed to make a protein.
3. They carry information from DNA into the cell's nucleus to the cytoplasm where proteins are formed.

rRNA or Ribosomal RNA:

1. rRNA is the basic component of the ribosome and is formed from the nucleolar organizing region of chromosomes in eukaryotes.
2. It plays a structural and catalytic role during the translation of mRNA into proteins.

tRNA or Transfer RNA:

1. tRNA accounts for only $0.025\%$ the total DNA content.
2. The primary structure of tRNA is considered to be the cloverleaf model.
3. The function of tRNA is to regulate essential amino acids according to the nucleotide sequence of mRNA.
