Here's a breakdown:
* DNA Structure: DNA is a double helix, meaning two strands of nucleotides are twisted around each other.
* Base Pairing: Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. The bases are adenine (A), guanine (G), cytosine (C), and thymine (T).
* Hydrogen Bonds: Adenine always pairs with thymine (A-T), and guanine always pairs with cytosine (G-C). These base pairs are held together by hydrogen bonds, which are weak but numerous.
* Importance: Hydrogen bonds are essential for DNA function:
* They allow the two strands to separate during DNA replication and transcription.
* They provide stability to the DNA molecule, ensuring its integrity.
