Question

find the length of DNA fragment having 30%cytosine ans 130 hydrogen bonds​

Answer 1

Answer:

Hydrogen bonding is the result of the dipole-dipole force between an electronegative atom and a hydrogen atom attached to nitrogen, oxygen, or fluorine. The energy of the hydrogen bond (about 5 to 30 kJ / mol) is comparable to a (Week) covalent bond (155 kg / mol). A particular connective bond is about 20 times stronger than an intermittent hydrogen bond. These bonds can be formed between molecules (intermittent), or even between different parts of the same molecule. [2] Hydrogen bonding is a strong stable dipole-dipole van der Wael force, but with connective bonds, ionic bonds and metallic bonds. It is weak. Hydrogen bonding is between the valence bond and electrostatic intermolecular attraction. Such bonds are found in both organic molecules (DNA) and inorganic molecules (water).

The intermittent hydrogen bond is responsible for the high boiling point of water (from 100 ° C). This force creates structures of secondary, tertiary and class IV proteins and nucleic acids.
