What are three major classes of RNA found in the cell?

Three major classes of RNA found in the cell are:

Messenger RNA Transfer RNA Ribosomal RNA

Explanation:

Messenger RNA: function is to carry the genetic code from the nucleus to the cytoplasm. Ribosomal RNA: is present in the cytoplasm of the cell. ribosomal RNA plays a major role in the synthesis of protein. Transfer RNA: is present in cellular cytoplasm, the function of tRNA is to transfer the amino acids to the ribosome.
