what is made of dna and some protein
All proteins are made up of combinations of 20 different amino acids. The RNA code (like DNA) is written in just four different chemical 'letters' - bases. How can a code with four letters identify 20 different amino acids?
DNA is made of two chains of several nucleotides. And a nucleotide is made of one carbohydrate, one phosphate and one nitrogen-containing base. View the site below for a better understanding of the nucleic acid structure.
