Product Description
This 41-slide powerpoint presentation covers 'Topic 7.1 - DNA Structure & Replication' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note.

The topic has been divided into three sections:

     • A - DNA Structure
     • B - DNA Replication
     • C - Function & Application

The presentation itself contains minimal information as it is intended to be used with teacher guidance. There are sometimes 'Video' throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.

Suggested Use:

I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the IB Bio Understandings. The remaining class time is spent reinforcing the knowledge or working on activities, written test practice, or nature of science.

**These presentations are based on the IB Biology Course Guide and do not follow any textbook

As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

==============================

Understandings:

     - U1: Nucleosomes help to supercoil the DNA.
     - U2: DNA structure suggested a mechanism for DNA replication.
     - U3: DNA polymerases can only add nucleotides to the 3’ end of a primer.
     - U4: DNA replication is continuous on the leading strand and discontinuous on the lagging strand.
     - U5: DNA replication is carried out by a complex system of enzymes.
     - U6: Some regions of DNA do not code for proteins but have other important functions.

Applications:

     - A1: Rosalind Franklin’s and Maurice Wilkins’ investigation of DNA structure by X-ray diffraction.
     - A2: Use of nucleotides containing dideoxyribonucleic acid to stop DNA replication in preparation
             of samples for base sequencing.
     - A3: Tandem repeats are used in DNA profiling.

Skills:

     - S1: Analysis of results of the Hershey and Chase experiment providing evidence that DNA is the genetic
             material.
     - S2: Utilization of molecular visualization software to analyse the association between protein and DNA
             within a nucleosome.
