What are 3 types of RNA

Three major types of RNA are mRNA, or messenger RNA, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA, that serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled ...

Three major types of RNA are mRNA, or messenger RNA

Ribosomal RNA (rRNA), and Transfer RNA (tRNA).

Explanation:

Messenger RNA (mRNA) carries the instructions from the nucleus to the cytoplasm

The other two forms of RNA, ribosomal RNA (rRNA) and transfer RNA (tRNA), are involved in the process of ordering the amino acids to make the protein.
