- Base Pairing
-
Base pairing in DNA was determined by Chargoff. It is also known as Chargoff's rule. Guanine base pairs with Adenine and Cytosine base pairs with Guanine.
A=T
G=C

These are subunits of nucleic acids. They consist of:
1. 5-Carbon sugar
2. Phosphate group
3. Nirogenous base
A DNA nucleotide consists of
