- Biomolecule: nucleic acid
codes for genetic information
Nucleotide: phosphate group, sugar, nitrogenous base
2 types: DNA and RNA

Chromosomes
one long continuous thread of DNA that consists of numerous genes along with regulatory information
human body cells have 46

DNA wraps at regular
intervals around pro-
teins called histones,
forming chromatin - similar to beads on a string

Base Pairing Rule: the bases of the two DNA strands always pair up
in the same way.
thymine (T) always pairs with adenine (A)
(A=T)
cytosine (C) always pairs with guanine (G)
(C≡G)
