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 ...

CRISPR—Clustered Regularly Interspaced Short Palindromic Repeats—is the microbial world’s answer to adaptive immunity. Bacteria don’t generate antibodies when they are invaded by a pathogen and then ...

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 ...
