ANATOMY

Detailed explanation-1: -As per the codons on mRNA, tRNA provides the amino acids to the ribosome (site of protein synthesis). The nucleotides of tRNA are complimentary to the three nitrogenous bases of the codon on the mRNA, hence they are called anticodons.

Detailed explanation-2: -The correct option is D codons. The triplets of nitrogenous bases in DNA that code for amino acids are called codons.

Detailed explanation-3: -(KOH-don) A sequence of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid. Certain codons signal the start or end of translation. These are called start or stop (or termination) codons.

Detailed explanation-4: -Codons are made up of any triplet combination of the four nitrogenous bases adenine (A), guanine (G), cytosine (C), or uracil (U). Of the 64 possible codon sequences, 61 specify the 20 amino acids that make up proteins and three are stop signals.

Detailed explanation-5: -It is the messenger RNA codon that carries the message specifying a certain amino acid; it is the transfer RNA that transfers that amino acid to the growing protein chain. The tRNA anticodon is a sequence of three nucleotides that are the complement of the three nucleotides in the mRNA codon.
