Some DNA-Binding Enzymes Prefer Fake DNA

Not only can synthetic molecules mimic the structures of their biological models, they can also take on their functions and may even successfully compete with them, as an artificial DNA sequence now shows.

Gut Cells Turn Up in Lung Tumours

Tumours are notoriously mixed up; cells from one part often express different genes and adopt different sizes and shapes than cells from another part of that same tumour. This discovery was still a surprise, however.

Weekend Reads, week 12

Stuff to read this week gives you everything from how genetics is changing our understanding of ‘race’, to beer being brewed with CRISPR technology. 

Clinical Genomics 101: Biological Samples

There are a number of different ways in which genetic material can be collected and the choice of which technique is used is typically decided by a variety of factors. We discuss the different techniques available.

Caught on Film: Mutating DNA

Until now, biologists have only had crude methods for estimating the average rates and effects of mutations. But in a new study, biophysicists have documented individual mutations as they happen in bacterial cells.
