Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is a description of an anticodon?
A
a set of 3 nitrogen bases
B
opposite of a codon
C
code on mRNA
D
Found on DNA
Explanation: 

Detailed explanation-1: -An anticodon is a trinucleotide sequence located at one end of a transfer RNA (tRNA) molecule, which is complementary to a corresponding codon in a messenger RNA (mRNA) sequence.

Detailed explanation-2: -An anticodon is a sequence of three nucleotides in transfer RNA that binds to a corresponding codon and designates a specific amino acid. The anti-in anticodon means “opposite to”-in reference to how it corresponds to the codon.

Detailed explanation-3: -Explanation: An anticodon is the three-base sequence, paired with a specific amino acid, that a tRNA molecule brings to the corresponding codon of the mRNA during translation. The anticodon sequence is complementary to the mRNA, using base pairs in the anti-parallel direction.

Detailed explanation-4: -The codon and anticodon are always antiparallel to each other when base-paired.

Detailed explanation-5: -A codon is a three-nucleotide or triplet sequence found on mRNA that codes for a certain amino acid during translation. The anticodon is a three-nucleotide sequence found on tRNA that binds to the corresponding mRNA sequence. The amino acid transported by the tRNA molecule is determined by the anticodon sequence.
