BIOMOLECULES AND ENZYMES

Detailed explanation-1: -More Information. DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .

Detailed explanation-2: -The Adenine-Thymine base pair is held together by 2 hydrogen bonds while the Guanine-Cytosine base pair is held together by 3 hydrogen bonds. That is also the reason why the two strands of a DNA molecule can be separated more easily at sections that are densely populated by A-T base pairs.

Detailed explanation-3: -Answer and Explanation: The number of specific bases is determined by the number of hydrogen bonds each base pair can make. Adenine pairs with thymine in DNA or uracil in RNA. Adenine creates two hydrogen bones with either thymine or uracil because it has two nitrogen atoms in its ring that can form hydrogen bonds.

Detailed explanation-4: -Base pairing between adenine and thymine can be found in DNA only. There are two hydrogen bonds holding the two nitrogenous bases together. One of the hydrogen bonds is formed between one of the Hydrogen atoms of the amino group at C-6 of adenine and the Oxygen atom of the keto group at C-4 of thymine.

Detailed explanation-5: -Final answer: In DNA the complementary bases are adenine and thymine, guanine, and cytosine.
