DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which molecules are involved in protein synthesis?
A
transfer RNA, introns, and mutagens
B
messenger RNA, introns, and ribosomal RNA
C
ribosomal RNA, transfer RNA, and mutagens
D
messenger RNA, ribosomal RNA, and transfer RNA
Explanation: 

Detailed explanation-1: -Three main types of RNA are involved in protein synthesis. They are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). rRNA forms ribosomes, which are essential in protein synthesis.

Detailed explanation-2: -The three main types of RNA directly involved in protein synthesis are messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA(tRNA).

Detailed explanation-3: -Rather, the translation of mRNA into protein depends on adaptor molecules that can recognize and bind both to the codon and, at another site on their surface, to the amino acid. These adaptors consist of a set of small RNA molecules known as transfer RNAs (tRNAs), each about 80 nucleotides in length.

Detailed explanation-4: -Translation is catalyzed by a large enzyme called a ribosome, which contains proteins and ribosomal RNA (rRNA). Translation also involves specific RNA molecules called transfer RNA (t-RNA) which can bind to three basepair codons on a messenger RNA (mRNA) and also carry the appropriate amino acid encoded by the codon.
