Shows all of the major and minor grooves. Can also be used to demonstrate replication. Features 22 base pairs comprised of: 11 each of thymine (orange), adenine (blue), guanine (green), and cytosine (yellow). Side chain: 44 each of deoxyribose (red) and..

This model can be used in its ladder form and unzipped to demonstrate the process of replication. Features 12 base pairs comprised of: six thymine (orange) and six each of adenine (blue), guanine (green), and cytosine (yellow). Side chain: 24 each of de..
