Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The anticodon AGA is complementary to the mRNA codon TCT.
A
true
B
false
Explanation: 

Detailed explanation-1: -Answer and Explanation: The given statement is true. Anticodon is defined as a complementary sequence to a specific set of a codon found in tRNA molecule.

Detailed explanation-2: -An anticodon is a sequence of 3 bases, and is complementary to the codon for an amino acid. For example, the amino acid lysine has the codon AAG, so the anticodon is UUC.

Detailed explanation-3: -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. The next mRNA codon is now exposed in the ribosome’s other docking site.

Detailed explanation-4: -Anticodons are sequences of nucleotides that are complementary to codons. They are found in tRNAs, and allow the tRNAs to bring the correct amino acid in line with an mRNA during protein production. During protein production, amino acids are bound together into a string, much like beads on a necklace.

Detailed explanation-5: -Bacillus subtilis tRNA(Pro) with the anticodon mo5UGG can recognize the codon CCC.
