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).

Rewriting rRNA Alters the Architecture of the Nucleolus

Ribosomes carry out the cell's most essential function-translating genetic information into proteins.

Uncovering the Molecular Roots of Neural Stem Cell Decline

Age often brings a gradual decline in the ability to learn new things and retain memories. This phenomenon, often associated with the elderly, is linked to the brain's deteriorating capacity to generate new neurons-a process that primarily occurs in the hippocampus -as neural stem cells (NSCs) divide and mature.

How DNA Packaging Shapes p53 Activity

Each cell in our bodies carries about two meters of DNA in its nucleus, packed into a tiny volume of just a few hundred cubic micrometers-about a millionth of a milliliter.

Precision Control of Gene Switches Offers Hope for Tackling Inflammatory Diseases

Genes, fragments of DNA located on our chromosomes, control much of what happens in cells. Each cell activates only the genes it needs, silencing the rest through molecular "switches" present on each gene.
