The correct option is C Protein synthesis
There are three types of non-genomic RNA. They properly work in protein synthesis. The non-genomic RNA are as follows -mRNA, tRNA, and rRNA.The three roles of this three non-genomic RNA in protein synthesis-
1. mRNA carries a genetic information copied from DNA in the form of series of three base codes they are specific amino acids.
2. tRNA is the key to deciphering the code words in mRNA. Each type of the amino acid has its own type of tRNA, which binds it and carries it to the growing end of polypeptide chain if the next code word on mRNA calls for it. The correct tRNA with its attached amino acid is selected at each step because each specific tRNA contains three specific amino acid triplet, which is complementary to the mRNA.
3. rRNA is the associates with the set of protein to form a ribosome.
So, the correct answer is option B
