Nucleotide structure

Nucleotide structure

1. 3 chemistry groups

   • phosphate
   • pentose sugar
   • nitrogenous base

2. sugar phosphate backbone with nitrogenous base sticking out

3. bases

   • DNA
     • Adenine
     • thymine
     • cytosine
     • guanine
   • RNA
     • adenine
     • uracil
     • cytosine
     • guanine
   • A binds with T/U
   • C binds with G

4. at 2' DNA has H and RNA has OH

   • lack of OH prevents hydrolysis
     • DNA more stable
