Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The anticodon of a particular tRNA molecule is
A
complementary to the corresponding mRNA codon.
B
complementary to the corresponding triplet in rRNA.
C
the part of tRNA that bonds with a specific amino acid.
D
catalytic, making the tRNA a ribozyme.
Explanation: 

Detailed explanation-1: -The anticodon of the tRNA is complementary to the corresponding codon of the mRNA molecule. As a result, the tRNA binds to the mRNA codon through complementary base-pairing. Thus, the tRNA anticodon is complementary to the corresponding mRNA codon. Therefore, the given statement is true.

Detailed explanation-2: -The tRNA is located in the ribosome’s first docking site. This tRNA’s anticodon is complementary to the mRNA’s initiation codon, where translation starts. The tRNA carries the amino acid that corresponds to that codon.

Detailed explanation-3: -21 The anticodon of a particular tRNA molecule is complementary to the corresponding triplet in rRNA complementary to the corresponding mRNA codon: the part of tRNA that bonds to a specific amino acid.

Detailed explanation-4: -When mRNA is translated into a polypeptide chain during translation, the codons of mRNA base pair with complementary RNA sequences in tRNA molecules (which carry amino acids to the growing polypeptide) at the ribosome. mRNA codons and tRNA anticodons are complementary to each other.
