DNA REPLICATION

DNA Replication  Process of DNA making a copy to prepare for mitosis and meiosis.  Semiconservative model-  Occurs during Interphase Of the cell cycle Of the cell cycle

 Enzymes- proteins with a “special job”  DNA polymerase adds nitrogen bases to open strand  Helicase separates the strand

DNA Replication Animation  library/06/3/l_063_02.html library/06/3/l_063_02.html library/06/3/l_063_02.html DNA Replication Simulation  Base pair sequence- A-C-T-A-G-C
