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.
