DNAreplication


 * DNA replication**

DNA replication occurs before the process of mitosis producing two copies of identicle DNA that are ready to separate into two new cells. Enzymes attach to the strand of DNA (in larger cells replication occurs in hundreds of places) and begin to "unzip" the DNA in both directions until the entire strand in separated. After separation has occured another set of enzymes come in and begin to rebuild the two strands of DNA. They pull in other bases and begin to attach them to the right pairs, resulting in two new strands of DNA. This can be found in the Textbook on pages 287-298.


 * __Important Facts__**
 * DNA replication called **DNA polymerase**
 * Replication possible because of **Hydrogen bonds** between bases
 * Occurs in the **Nucleus**
