What are the major functions of DNA?Controls our cellular activitiesDetermines our traits Protein Synthesis
DNA Structure ReviewDouble HelixBase Pairs
DNA ReplicationDefine Replication:A copy or reproduction
How does the structure of DNA allow for replication to occur?
Each strand of DNA has all the information needed to reconstruct the other halfStrands are called Complementary
The Process1. Special enzymes move along the DNA strands unwinding and unzipping the DNA
2. Other enzymes add new nucleotides to create the two new strands from each original strand of DNA3. The two DNA molecules wind up
How do these new nucleotides line up?
Where do the free floating nucleotides come from?Our digestive and circulatory systems!Nucleic Acids are digested into individual nucleotides and transported to body cells(Vegetables and Dairy)
The Final ProductTwo identical DNA strands each has one old strand and one new strandSemi-Conservative
Why do we need two sets of genetic information?CELL DIVISION!!!
