Study Notes
DNA Structure and Function
- The molecule being discussed is DNA (Deoxyribonucleic acid).
DNA Double Helix
- The most common form of the DNA double helix is B-DNA, a right-handed double helix.
Nucleotide Components
- A nucleotide consists of three components:
- a five-carbon sugar called deoxyribose
- a phosphate group
- a nitrogenous base (adenine, guanine, cytosine, or thymine)
DNA Structure Inside the Cell
- Inside the cell, double-stranded DNA is coiled into a structure called chromatin, which is further condensed into visible chromosomes during cell division.
DNA Function
- The primary function of DNA is to store and transmit genetic information from one generation to the next.
