Rebecca Roberts is a science writer and communicator. She earned her PhD in molecular biology from the University of the Sunshine Coast in Australia and completed a two-year postdoctoral fellowship at ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we ...

The founder of a lab that used new DNA technology to link hairs found on Gilgo Beach victims to accused serial killer Rex ...

DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information ...

So how does protein synthesis make hair? If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell how to make a protein.

so histones bind with DNA very tightly. The basic repeating structural (and functional) unit of chromatin is the nucleosome, which contains eight histone proteins and about 146 base pairs of DNA ...

DNA can be cut up and separated, which can form a 'bar code' that is different from one person to the next. The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a ...

We are interested in homologous recombination not only because of the intellectual challenges it presents, but also on the insights it may bring to the mechanism of the repair of double strand breaks ...
