WebThe answer is that A-T and G-C pairs maximize the number of hydrogen bonds across the shared helical axis. A's hydrogen donors can pair up with T's hydrogen bond … WebThe constraint that specifically favors A-T and G-C base pairing is a chemical one. DNA has two strands that stay together due to hydrogen bonds between paired nitrogenous bases. Chemical side groups of each base allow hydrogen bond formation with only a specific nitrogenous base. Thus, A can form two hydrogen bonds only with T. coach store birch run mi

"WebHydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom. Hydrogen bond strengths range from 4 kJ to 50 kJ ... " - H bonds gc at
