26

3 DNA Components

1. 2'-deoxy-D-ribose-phosphate backbone
2. 3'-5' phosphodiester linkage
3. 1'-Beta-glycolidic linkage to bases

27

Chargaff's Rule

Amount of A equals amount of T and amount of G equals amount of C in DNA samples

28

5 Structural Properties of DNA

1. Antiparallel double strands
2. Right-handed helical twist
3. Phosphate sugar backbone outside w/ (anti)-bases inside, resulting in major and minor grooves
4. Complementary H-bonded AT and CG base pair planes perpindicular to helical axis
5. Sequential base pairs stack along helical axis, 10bp per helical turn

29

Topoisomers

DNA molecules w/ same number of base pairs that differ in coiling amount

30

Prokaryotic vs. Eukaryotic DNA

Proks have circular plasmids whereas euks have linear chromatin
