DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A sequence of 3 nitrogen bases on mRNA that codes for an amino acid.
A
Anticodon
B
Codon
C
Amino Acid
D
DNA Polymerase
Explanation: 

Detailed explanation-1: -The triplets of nitrogenous bases in DNA that code for amino acids are called codons. There are 64 codons, 61 of which code for different amino acids. The remaining three codons are stop/termination codons, which act as stop signals for protein synthesis.

Detailed explanation-2: -Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code).

Detailed explanation-3: -codon, in genetics, any of 64 different sequences of three adjacent nucleotides in DNA that either encodes information for the production of a specific amino acid or serves as a stop signal to terminate translation (protein synthesis).

Detailed explanation-4: -codon: a group of three nitrogen bases found in mRNA that is the code for one amino acid.
