Answer:
The correct answer is - combinations of nucleotides
Explanation:
The codes for amino acids are encoded in the DNA and RNA in the form of the trinucleotide codons that contain three base sequences which copied in the complementary bases sequence mRNA and then decoded by the ribosome with help of tRNA to produce the original sequence in amino acid sequence or peptide chain.
This nucleotide is also code in the set of 3 base sequences similarly one amino acid is made up of the triplet code.
