- The DNA molecule has a double helix structure, resembling a twisted ladder.
- The sides of the ladder are made of alternating sugar and phosphate groups, forming the backbone.
- The rungs of the ladder are composed of nitrogenous base pairs: adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C).
- These base pairs are held together by hydrogen bonds, ensuring specific and stable pairing.
- The two strands of DNA run in opposite directions (antiparallel), which is essential for replication and protein synthesis.
- This structure allows DNA to store genetic information efficiently and to be accurately copied during cell division.
- The sequence of base pairs along the strands encodes the instructions for building proteins and controlling cellular functions.
