DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Researchers Use Retron Systems to License DNA for Cellular Tasks

Stepping away from its billions-of-years-old role as a genetic "blueprint," DNA is now embarking on a new journey as an active "field agent" within cells. This research by a team led by Professor Jongmin Kim and Ph.D. candidate Geonhu Lee from the Department of Life Sciences at POSTECH (Pohang University of Science and Technology) was published in the online edition of the international chemistry journal, Nature Chemistry.

Study Highlights the Vast Untapped Potential Within the Global Protein Universe

The number of known proteins is infinitely small in comparison to the universe of possible proteins which could in theory be realized. Yet these known proteins are the only major training ground for future protein design. Understanding how representative these proteins are of the overall potential diversity can therefore help inform strategies for a wide range of applications, including therapeutic, biocatalysis, or biomaterials development.
