Presentation describing how the Double Helical model of DNA was determined and how it has helped us understand various biological processes and also design new molecules.

A collections of Video tutorials for using UCSF Chimera for:

1: Loading PDB coordinates into the software, manipulating the structure in 3D, and saving session.

2: Menus

3: Selecting parts of a protein structure

4: Analyzing and exploring a protein structure

5: Comparing the structures of two related proteins/domains and visualizing the superposed structures of these proteins/domains.

This file guides you to use UCSF Chimera to explore the structures of substrate-DNA and product-DNA bound complexes with a restriction enzyme.

Instructions for preparing your computer for visualizing and exploring structures from the Protein Data Bank
