Modelling
Modelling is a key part of synthetic biology. Some experiments take too long, are far too expensive, or the information required just can’t be found via lab work. This is where modelling comes in. We take information from the biologist, construct a theoretical framework, and then feed back to people in the lab about what they should do.
In our project we have come up with a number of models, ranging from cell division to equilibrium reactions.

A big problem biologists encounter is the uncertainty of bonding especially in our design where zinc fingers bind to cells. Therefore it is important to come up with a model which can calculate the number of cell and zinc finger binding sites required for a given output. This page discusses this and shows a program designed to dictate concentrations for the biologists to use.
DNA Beading Model
Once we had a method of calculating the concentration of cells needed we had to model the number of cells required to make a certain shape. We also needed to invent a novel approach to creating 2D shapes using cells, this page discusses bonding them to a longer string of DNA to form a pattern.
DNA Origami Glue Modelling
This page contains the model which discusses the use of DNA as an oligonucleotide adhesive using to create 2D and 3D structures and shapes.
Cell Growth Interactions
This section deals with the problem of what would happen to the previous shapes as time passes and cells grow.
Tetrahedron Construction
This shows how a 3D structure could be created from the minimum amount of DNA using tetrahedrons as a base to build from. Cells would then be bound to the outside.
Cube Construction
Similar to the previous, this uses cubes to create 3D shapes and discusses the minimum size need for DNA origami shapes.
