History of the Molecule
** Consists of two chains of nucleotide units in a twisted ladder-like structure. (resembles a spiral staircase)
-- Only 2 combinations of base pairs can form the rungs of the DNA molecule.
Adenine - Thymine (A-T) AND Guanine – Cytosine (G-C)
--This specific matching up of the nitrogenous bases is called complementary base pairing.
DNA is able to _________________ itself.
How does DNA form duplicates of itself during mitosis and meiosis?
