The correct answer is c) DNA.
The instructions for making proteins come originally from DNA. DNA is a macromolecule made of polynucleotide. Each nucleotide made of a phosphate, deoxyribose sugar and one of the four nitrogenous bases. The nitrogenous bases are adenine (A), guanine (G), cytosine (C) and thymine (T). The sequence of three bases in the DNA called codon. Each codon of the DNA codes for a particular amino acid for the synthesis of protein. Protein synthesis begins with the copying of the genetic information from DNA into a messenger RNA (mRNA) then mRNA is arrange amino acid sequence into a protein molecule.
