Detailed explanation-1: -The bases of one strand bond to the bases of the second strand with hydrogen bonds. Adenine always bonds with thymine, and cytosine always bonds with guanine. The bonding causes the two strands to spiral around each other in a shape called a double helix.
Detailed explanation-2: -DNA stores biological information in sequences of four bases of nucleic acid-adenine (A), thymine (T), cytosine (C) and guanine (G)-which are strung along ribbons of sugar-phosphate molecules in the shape of a double helix.
Detailed explanation-3: -Which of the following models most accurately represents the structure of DNA? Double stranded structure pairing G-C, T-A, C-G in the middle with phosphate bonds on the outside.
Detailed explanation-4: -Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.
