hydrogen bonding in dna

>Among purines adenine (A) pairs only with the pyrimidine thymine (T) and vice versa. Similarly guanine (G) pairs only with cytosine (C) and vice versa. There are two weak hydrogen bonds between A and T or T and A. There are three weak hydrogen bonds between ..

Hydrogen bond is an intermolecular force of attraction that exists in the molecules that have hydrogen atom bonded to nitrogen, oxygen, or fluorine. Hydrogen bond is a strong dipole-dipole attraction. When a H-atom is bonded..

The electrostatic force of attraction between the hydrogen atom of one molecule and more electronegative atom of the same or another molecule, is called hydrogen bond. When hydrogen atom gets bonded to atoms of highly electronegative elements ..

Hydrogen Bonding - The electrostatic force of attraction between the hydrogen atom of one molecule and more electronegative atom of the same or another molecule, is called hydrogen bond. When hydrogen atom gets bonded to atoms of..

It is the most widely used technique in genetic engineering. It involves the formation of recombinant DNA and its introduction into an appropriate host. Recombinant DNA is the DNA formed by combining DNAs from different organisms. The technique requires skilful h..

Formation of Polynucleotide Each DNA molecule has two such polynucleotide chains joined to each other by hydrogen bonds. The hydrogen bonds are between the nitrogenous bases of the opposite nucleotides. If the polynucleotide chains are the sides of ..

.9 - Base Pairing in DNA The nitrogen bases of the two opposite chains exhibit highly specific base pairing. A purine in one chain always pairs with a pyrimidine in the opposite chain. Among purines adenine(A) pairs only with the pyrimidine thymine (T)and vice versa. Similarly guanine (G)..

As the RNA chain grows, the transcribed region of the DNA molecule gets hydrogen bonded to the opposite strand and the two become spirally coiled to assume the original double helical form. When the last ribonucleotide is added, the RNA polymerase and RNA chain are co..

Electronic configuration: 1 - Hydrogen atom needs one more electron to attain the duplet. As four electrons are needed by the carbon atom, we can infer that there would be four hydrogen atoms involved in bonding wherein, each would share one electron with one electro..
