Explain the differences in the three types of RNA by connecting it to a factory.

kykrilka [37]

${\huge{\sf{\green{\underline {\underline {Answer }}}}}}$

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 .

RNA carries genetic information from the nucleus to ribosomes for the synthesis of proteins; while tRNA carries specific amino acids to the ribosomes to assist the protein biosynthesis, and on the other hand, rRNA provides the structural framework for the formation of ribosomes.
