The stages of interphase:
1. G1 stage before DNA synthesis
2. S DNA synthesis
3. G2 stage after DNA synthesis
The Mitotic Stage
Mitosis the division of the nucleus, follows interphase
-The sister chromatids separate into daughter chro
-Knowledge of DNA has lead ot an ability to manipulate the genes of organsims
-Cloned genes are used to alter the genome of viruses or cells
-Bacterial, plant, or animal cells.
