WebSep 4, 2024 · In DNA, hydrogen bonds form between bases on the two nucleotide chains and hold the chains together. Each type of base binds with just one other type of base: cytosine always bonds with guanine, and adenine always bonds with thymine. These pairs of bases are called complementary base pairs. Figure \(\PageIndex{3}\): Nucleic Acid WebThe thermal stability of a double-helical DNA segment thus depends on the base pair composition of the DNA fragment. In this exercise you will use a theoretical chemistry method to estimate the interaction strength …
Web1 day 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 regions are more ...
