How dna strands are held together

WebThe two strands of DNA in a double helix are held together by pairing between the nitrogenous bases in the nucleotides of each strand. The nitrogenous base of a DNA … WebThe nitrogenous bases of the two separate polynucleotide strands are bound together, according to base pairing rules (A with T and C with G), with hydrogen bonds to make double-stranded DNA. The complementary nitrogenous bases are divided into two groups, pyrimidines and purines.
