GoT-ChA! - Assessing How Mutations Affect DNA Structure in Single Cells

Scientists have created a new technique that can assess how mutations in the genome influence the packaging of DNA in cells. The genome is massive, and has to be carefully wrapped around proteins so ...

Revealing the Links Between RPA Mutations & Disease

Our DNA is compacted and arranged into chromosomes, most of which are shaped like X’s. The ends of the chromosomes' arms are protected with caps known as telomeres. Telomeres are made up of highly ...

DNA Mutations Replica

This module is a replica of a strand of DNA for eye color using light patterns controlled by an Arduino. The four light colors, red, green, blue, and yellow, represent the four nucleotide base pairs, ...
