A codon has a sequence A and specifies a particular B that is to be incorporated into C. What are A, B and C?
(a) A= 3 bases, B= amino acids, C= carbohydrates
(b) A= 3 bases, B= carbohydrates, C= amino acids
(c) A= 3 bases, B= protein, C= amino acids
(d) A= 3 bases, B= amino acids, C= protein
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.
Carbohydrates don't contain bases, thus we can rule out A and B.
The 3 bases specify an amino acid which link together to form a chain of protiens.
Hence the answer is D.
