Q. What are the three major types of RNA? What is meant by heterogeneous RNA?

Messenger RNA, or mRNA, transfer RNA, or tRNA, and ribosomal RNA, or rRNA, are the three main types of RNA.

The newly formed RNA molecule, a precursor of mRNA, is called heterogeneous RNA (hnRNA). The heterogenous RNA bears portions known as introns and portions known as exons. The hnRNA is processed in many chemical steps, introns are isolated and mRNA is created formed only of exons, the biologically active nucleotide sequences.
