tRNA itself is an RNA molecule with a conserved inverted L structure. One end of the tRNA contains an anticodon loop which pairs with a mRNA specifying a certain amino acid. There is a specific tRNA for each amino acid, 20 in all.
an anticodon loop
Amino acids in the protein
tRNA is attached with amino acid which is called charged. Amino acid attached to the enzyme that is called 3'OH aminoacyl tRNA synthesis. There are different type of tRNA that is specific tRNA around 20.
There is only a 2 tRNA anticodon loop. These loops are very important for the decoding of the mRNA. There are many nucleotides in the anticodon but the third anticodon is very less stringent.
amino acids is the answer in apex
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.
B. Amino Acid
I believe it's C.
