1. Please grab a white board, eraser and marker from the front DNA and Cell Reproduction Unit Review

2. Draw for me on your whiteboard a: Nucelotide (label all 3 parts)

3. Draw for me on your whiteboard a: Pyrimidine (draw how many rings)

4. Write out for me on your whiteboard what this stands for: DNA Deoxyribonucleic Acid

5. Write out for me on your whiteboard the steps of: DNA Replication 1)Helicase unwinds and unzips the DNA, by breaking hydrogen bonds between bases. 2)DNA Polymerase adds new nucleotides on to the template strand. 3)New bonds are made between sugars and phosphates on the new strand. 4)The new DNA molecule twists back into a double helix.

6. Draw for me on your whiteboard: Semi-conservative Replication

7. Draw for me on your whiteboard: Steps of Binary Fission (explain what is happening)
