The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...

“Our lab is generally interested in discovering and characterizing previously unknown or poorly understood factors that are essential for genome maintenance. This is particularly important in the ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

Researchers have discovered a tube-shaped structure that forms temporarily in a certain type of virus to deliver its DNA during the infection process and then dissolves after its job is completed. The ...

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University have ...

It's a common storytelling trope: the stubborn foe who is eventually revealed to be a much-needed friend. Biology has its own version. Cornell researchers have discovered that DNA packaging structures ...

In September 1970, Janet Mertz joined the biochemistry department at Stanford University. She was one of only six new graduate students in the department and the first female one admitted in nine ...

Unlike most cell types, which continuously divide, neurons have to last for the life of the organism. How do they do that? One way neurons stay healthy is by repairing their DNA as they transcribe it.
