Nucleotide
Monomer of DNA
DNA building block
Purine
Class of nitrogenous bases consisting of two fused rings
Pyrimidine
Class of nitrogenous bases consisting of one ring
Examples of Purines
Adenine and Guanine
Examples of Pyrimidines
Cytosine and thymine
Complementary base pair rule
States that adenine will always pair with thymine and cytosine will
always pair with guanine
Chargaff's rule
States that due to complementary base pairing the amounts or percent
of adenine/thymine and cytosine/guanine will be equal.
Double helix
Model discovered by Watson and Crick that depicts DNA as a twisted,
two sided ladder
Sides of double helix held toge
Alternating deoxyribose and phosphate groups
Rungs of ladder
complementary bases
