Towards the end of the week you will be required to begin a group presentation.  You can choose your topic (as long as it pertains to DNA) and can also choose your own method of presentation.  Just make sure you check it in with me by wednesday so I can approve it!

 

DNA is in the shape of a double helix with many repeating parts called nucleotides.  Each nucleotide consists of three parts:

     1. Base (A, G, C, and T)

     2. Sugar (Deoxyribose)

     3. Phosphate

Bases pair up with one another to create the "rungs of the ladder" while the sugar and the phosphate create the backbone of the DNA.

Replication of DNA occurs at a site called the replication fork.  There are several proteins that assist in the replication of DNA, these are:

     1. DNA polymerase I

     2. DNA polymerase III

     3. Primase

     4. Ligase

     5. Gyrase

     6. Helicase

Each protein has a specific function in DNA replication.  Can you explain the function of each protein listed?
