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 ...

Recombinant DNA (rDNA) refers to artificial DNA molecules that are created by combining genetic material from different sources. This technology involves the insertion of DNA fragments from one ...

A molecular oddity found in bacteria could hold the key to redesigning genomes at will, allowing researchers to insert, delete or flip large segments of DNA. Guided by an RNA molecule called a ‘bridge ...

Genome editing has advanced at a rapid pace with promising results for treating genetic conditions—but there is always room for improvement. A new paper by investigators from Mass General Brigham ...

Both proteins and DNA can carry marks, called epigenetic markers, that instruct when and which genes are expressed. Although many such markers have been described in proteins, epigenetic marks in DNA ...

Researchers from the Perelman School of Medicine at the University of Pennsylvania have invented a new way to map specific DNA markings called 5-methylcytosine (5mC) which regulate gene expression and ...
