DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Transfers and brings amino acids to ribosomes during protein synthesis
A
messenger RNA (mRNA)
B
ribosomal RNA (rRNA)
C
transfer RNA (tRNA)
D
RNA Polymerase
Explanation: 

Detailed explanation-1: -transfer RNA (tRNA), small molecule in cells that carries amino acids to organelles called ribosomes, where they are linked into proteins. In addition to tRNA there are two other major types of RNA: messenger RNA (mRNA) and ribosomal RNA (rRNA).

Detailed explanation-2: -Each tRNA molecule has two distinct ends, one of which binds to a specific amino acid, and the other which binds to the corresponding mRNA codon. During translation, these tRNAs carry amino acids to the ribosome and join with their complementary codons.

Detailed explanation-3: -When a tRNA recognizes and binds to its corresponding codon in the ribosome, the tRNA transfers the appropriate amino acid to the end of the growing amino acid chain. Then the tRNAs and ribosome continue to decode the mRNA molecule until the entire sequence is translated into a protein.

Detailed explanation-4: -Transfer RNA (abbreviated tRNA) is a small RNA molecule that plays a key role in protein synthesis. Transfer RNA serves as a link (or adaptor) between the messenger RNA (mRNA) molecule and the growing chain of amino acids that make up a protein.

Detailed explanation-5: -Each amino acid in a protein is delivered to the ribosome by yet another type of RNA: transfer RNA (tRNA).
