Detailed explanation-1: -Each type of tRNA molecule can be attached to only one type of amino acid, so each organism has many types of tRNA. Because the genetic code contains multiple codons that specify the same amino acid, there are several tRNA molecules bearing different anticodons which carry the same amino acid.
Detailed explanation-2: -Answer and Explanation: tRNAs have one amino acid attached per molecule.
Detailed explanation-3: -Motivation: The standard genetic code translates 61 codons into 20 amino acids using fewer than 61 transfer RNAs (tRNAs). This is possible because of the tRNA’s ability to ‘wobble’ at the third base to decode more than one codon.
Detailed explanation-4: -At one end, the tRNA has an anticodon of 3’-UAC-5’, and it binds to a codon in an mRNA that has a sequence of 5’-AUG-3’ through complementary base pairing. The other end of the tRNA carries the amino acid methionine (Met), which is the the amino acid specified by the mRNA codon AUG.
Detailed explanation-5: -Each tRNA is designed to carry a specific amino acid that it can add to a polypeptide chain. tRNAs bring their amino acids to the mRNA in a specific order.
