The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic ...

Genome editing-based therapies typically aim to treat disease by correcting underlying genetic mutations in patient's cells.

Scientists have recently been learning more about the importance of small bits of circular genetic material known as extrachromosomal DNA (ecDNA). These little circles of DNA can hitch a ride with ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by researchers at Goethe University Frankfurt, part of the Rhine-Main University ...

Stanford Medicine pediatric hematologist Agnieszka Czechowicz, MD, Ph.D., has devoted her research career to improving ...

A protein found in our cells has emerged as a secret weapon against biological aging, acting like a glue to repair damaged DNA and ward off neurological degeneration including that seen in motor ...

The story of life’s beginnings gets stranger when you look closely at viruses. These tiny entities seem to sit at the edge of ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

The retina is a thin layer of neural tissue at the back of the eye that detects light and converts it into signals, sent to the brain. During development, all the specialized neurons in the ...
