Three types of rna and their function

The three types of RNA are: messenger RNA, carrier RNA and ribosomal RNA.

Explanation:

Messenger RNA (mRNA): it is the type of RNA that presents itself in a smaller amount in a cell, constituting about 5% to 10% of all cellular RNA. It is translated into the protein synthesis process, and is therefore the one that encodes proteins. It has sequences of nitrogenous bases that determine which amino acids will be used to form a given protein. It is a very heterogeneous class of RNA.

Transporter RNA (tRNA): This RNA is responsible for making the codon and amino acid link. In summary, we can say that tRNA works as an adapter between mRNA and the amino acids that will constitute a protein. The tRNA is small and has a structure similar to that of a clover leaf that has four arms. Two of these arms are of great importance for this RNA to perform its functions: the amino acid arm and the anticodon arm. The amino acid arm binds to a specific amino acid, and the anticodon arm has a complementary sequence to the mRNA codon. The other two arms are important for maintaining the structure of this RNA molecule.

Ribosomal or ribosomal RNA (rRNA): composes the structure of the ribosome, an organelle that is the site of protein synthesis. Each ribosome is made up of two subunits and each of these subunits is made up of about three rRNA molecules and several associated proteins. It is estimated that this type of RNA represents approximately 80% of the total RNA in a cell.
