Bio Class 19

Today in class we took a quiz on "The Journey of Man" and then turned to the whiteboard for an activity. We discussed DNA and its properties such as: nucleotides: phosphate+sugar+base 

Adenine, thymine, guanine, cytosine: makes up DNA. Hydrogen bonds connect base pair.

Phosphate diester bond: through dehydration synthesis

Purines and Puyrimidines: 1 group vs 2 groups

3' base and 5' base: 

3 prime base has an OH group.

Special enzymes help to unzip DNA when mitosis in a cell occurs or there is a need for replication:
