Class Cells to Systems
Edwin Chargaff Rules
Amounts of A-T and G-C are equal but amounts differ between species
Nucleic acid are polymers
Monomers= Nucleotides
Base +sugar + phosphate= Nucleotides
Base can be made of Purine or Pyrimidine
Examples of Purines= Adenine/ guanine
Examples of Pyrimidine= Thymine, uracil, cytosine
Sugar can be Deoxyribose or ribose
DNA Synthesis
New DNA is synthesized from dNTPs
During replication, 3’ OH group of last nucleotide attacks 5’ phosphate
group of incoming dNTP
Phosphates are cut off
Two nucleotides form a phosphodiester
This causes phosphate ions to be released
