Report Abuse. 1  DNA is interior the type of a double helix. the backside pairing rule describes the complementarity of the bases. Adenine is going with Thymine; Cytosine with Guanine. the cost of this would not lie in guy or woman bases, yet fairly interior the final base sequence. 2  Hydrogen bonds join them up.
See Fig. 1. The nucleotides within each strand are held together by the phosphodiester bonds between the 5' carbon of one nucleotide and the 3 ' carbon of the adjacent nucleotdie. These strong covalent bonds form the the glue that holds the sugar/phosphate backbone together and thus act to keep each strand together.The two strands of DNA are held together by weak hydrogen bonds (remember, something must hold them together!) between the nitrogenous bases.The interesting (and very important) aspect of the Watson-Crick model is that these hydrogen bonds are base specific.he two strands of DNA are held together by weak hydrogen bonds (remember, something must hold them together!) between the nitrogenous bases.
