Here's a breakdown:
* DNA Structure: DNA consists of two strands that twist around each other to form a double helix. These strands are held together by the pairing of nitrogenous bases.
* Base Pairing: The bases in DNA are adenine (A), guanine (G), cytosine (C), and thymine (T). Specific pairing rules exist:
* Adenine (A) always pairs with thymine (T).
* Guanine (G) always pairs with cytosine (C).
* Hydrogen Bonds: These base pairs are held together by hydrogen bonds, which are weak bonds formed between a hydrogen atom and a highly electronegative atom (like oxygen or nitrogen) on another molecule. These bonds are crucial for maintaining the stability of the DNA molecule.
