what is monomers in dna
The monomers of DNA are called nucleotides, and the polymer is a polynucleotide. There are four different nucleotides in DNA called A, T, G, and C for the nitrogenous base sidegroup (adenine, thymine, guanine, and cytosine respectively) attached to the sugar-phosphate backbone (deoxyribose-phosphate) of a nucleotide.he monomer units of DNA are nucleotides. Each of these consist of  a 5-carbon sugar which is deoxyribose, a nitrogen containing base  attached to the sugar and a phosphate â¦ group. Judy Olmsted. 78,524 Contributions.
