DNA replication is required to maintain the integrity of genomic information. This article describes the process of DNA replication, in a step-by-step manner.

DNA replication requires unwinding of the complementary two-stranded structure of DNA. This process is mediated by the severance of the hydrogen bonds that hold the bases together; the result is the formation of two single strands. The resultant Y-shaped appearance in this region of DNA is called the replication fork. The initiation of replication occurs … More DNA replication is required to maintain the integrity of genomic information.

DNA fragments from ancient hominins reveal new branches of the Denisovan lineage

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 hominins to modern people living in Island Southeast Asia and New Guinea now suggests that the ancestry of Papuans includes not just … More DNA fragments from ancient hominins reveal new branches of the Denisovan lineage

Biosynthesis of widespread pigments from bacteria revealed

Researchers from Goethe University and TU Munich decode biosynthesis of aryl polyene pigments Bacteria can protect themselves from the attack of free radicals using specific natural products in their membranes. The biosynthesis of one of the most common protective pigments that could also be of interest for the medical and cosmetic industries has now been … More Biosynthesis of widespread pigments from bacteria revealed
