BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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: -Bases pair up with each other in a consistent way, and this process is called complementary base pairing, or Watson-Crick base pairing. This consistent pairing of bases allows DNA to accurately replicate itself. It also allows DNA to be transcribed accurately into RNA and then translated from RNA to amino acids.

Detailed explanation-3: -In DNA, the nitrogen bases are named guanine, cytosine, adenine, and thymine, and they will connect with each other by forming bonds (specifically, hydrogen bonds) with their hydrogen atoms. Guanine always bonds with cytosine, which makes them a pair of complementary bases.

Detailed explanation-4: -Base Pair The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.
