As we have already seen in the previous section the nitrogenous bases are bonded together through hydrogen bonds and these hydrogen bonds are responsible for holding the two strands of DNA together. Hydrogen bonding actually plays a very crucial role inside a DNA molecule. The foremost reason is … Zobacz więcej DNA is a double-stranded structure that serves as a carrier of biological information for most organisms. The two strands of DNA are composed of nucleotides and each nucleotide is a combination of … Zobacz więcej The structure of a DNA molecule is a double helix. This was discovered by two scientists James Watson and Francis Crick and … Zobacz więcej On an absolute scale the energy of a hydrogen bond ranges between 8 KJ/mol to 29 KJ/mol. Therefore, hydrogen bonds are much weaker as compared to covalent bonds in which the energy level ranges in hundreds. As … Zobacz więcej The number of hydrogen bonds in a DNA molecule depends upon the nitrogenous bases present in the molecule. As discussed earlier adenine and thymine are connected through two hydrogen bonds amongst which … Zobacz więcej Witryna2 mar 2024 · hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is …
