Ancient DNA reveals new branches of the Denisovan family tree

It's widely accepted that anatomically modern humans interbred with their close relatives, the Neanderthals and Denisovans, as they dispersed out of Africa. But a study examining DNA fragments passed down from these ancient ...

Biologists develop new method of cloning

DNA, which contains the genetic information of an organism, consists of long chains of nucleotides. In order to study the functions based on the sequence of these building blocks, DNA molecules must be inserted in carrier ...

A record-long polymer DNA negative

A fragment of a single strand of DNA, built of the nucleobases cytosine and guanine, can be imprinted in a polymer—this has been shown by chemists from Warsaw, Denton and Milan. The resulting artificial negative, with a ...

CasPER—a new method for diversification of enzymes

A new study published in the Metabolic Engineering Journal describes a method based on CRISPR/Cas9, which enables flexible engineering of essential and nonessential enzymes without additional engineering. This has multiple ...

The long and the short of DNA replication

The process of copying DNA is complex choreography that requires rapid speeds and pin-point precision. Discovering the intricate details of this process could identify new ways to target diseases, such as cancer, and KAUST ...
