Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following carries amino acids to the site of protein synthesis?
A
mRNA
B
rRNA
C
tRNA
D
nRNA
Explanation: 

Detailed explanation-1: -Definition. 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-2: -transfer RNA (tRNA), small molecule in cells that carries amino acids to organelles called ribosomes, where they are linked into proteins.

Detailed explanation-3: -tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.

Detailed explanation-4: -One end of the tRNA matches the genetic code in a three-nucleotide sequence called the anticodon. The anticodon forms three complementary base pairs with a codon in mRNA during protein biosynthesis. On the other end of the tRNA is a covalent attachment to the amino acid that corresponds to the anticodon sequence.
