DNA Structure & Function

Nucleoside vs. Nucleotide
- Nucleoside is base + ribose
- Nucleotide is base + ribose + phosphates
Pyrimidines
Purines
Chargraff's rule
- Amount of A will always equal T
- Amount of C will always equan G
Histones
- Order DNA into nucleosomes like beads on a string
- Further organized into chromosomes`
DNA ligase functions
- Joining of Okazaki fragments
- DNA Repair
DNA repair mechanisms
- Recognition of damage (lesion)
- Removal (excision of damage)
- Replace (fill the gap) using sister strand as a template
- Ligation
Steps of DNA synthesis
Nucleotide bonding
