WebSep 12, 2024 · Base pairs keep the double strand of DNA together. If we think of DNA as a twisted ladder, each rung is a pair of nitrogenous bases, such as adenine and thymine or guanine and cytosine. Remember ... Web13 hours ago · No. of H- bond = 2 * No. of AT base pairs + 3 * No. of GC base pairs. Hence, if 100 base pairs are present in a DNA structure with 30 AT base pairs and 70 GC base pairs the number of hydrogen bonds can be calculated as follows: No. of H-bond = ( 2 X 30 ) + (3 X 70 ) = 270 H-bonds. The DNA molecules that consist of more GC-rich …
