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).

New Method Uses Light to Activate Protein Functions

Scientists can now use light to activate protein functions both inside and outside of living cells. The new method, called light-activated SpyLigation, can turn on proteins that are normally off to allow researchers to study and control them in more detail.

Entry of Aging-Associated Enzymes into Human Genetic Material

An enzyme that controls aging and other metabolic processes accesses human genetic material to modify gene expression within the cell, according to a new study. Images of a sirtuin enzyme bound to a nucleosome, a tightly packed complex of DNA and proteins called histones, have been created by a team led by Penn State researchers.
