Researchers uncovered millions of ancient plant DNA switches—some older than flowering plants themselves—revealing a hidden evolutionary blueprint stretching back 400 million years. Most people have ...

A new role for DNA loops in repairing genetic damage
When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its ...
In 1869, Swiss scientist Friedrich Miescher isolated a mysterious substance from cell nuclei—an overlooked finding that would later reshape biology and our understanding of life itself. A ...
Authorities confirm the DNA belongs to Nancy Guthrie, 84, who was last seen on Jan. 31 at her home in Arizona A sheriff in Arizona tells PEOPLE that investigators discovered "biological DNA" evidence ...
In a first, scientists have extracted DNA from a Renaissance-era drawing attributed to Leonardo da Vinci, but they can't be sure that the genetic material belongs to the Italian polymath. When you ...
When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...
The MCM helicase is broadly bound across the genome, and its phosphorylation is antagonistically regulated by the kinase DDK and the phosphatase RIF1–PP1. TRESLIN–MTBP recognises the phosphorylated ...
James Watson, a renowned molecular biologist and one of the Nobel Prize winners for discovering the structure of DNA, died Thursday after a brief illness, according to a statement from his former ...
His decoding of the blueprint for life with Francis H.C. Crick made him one of the most important scientists of the 20th century. He wrote a celebrated memoir and later ignited an uproar with racist ...
Is it the invasion of the genome snatchers? Just in case the idea of aliens walking around in human skin suits wasn’t frightening enough. An outlandish study asserts that aliens might have abducted us ...
Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...
The Age of AI will rely on massive volumes of data that can be easily stored and retrieved—and bioscience may have an ingenious solution. A scientist examines a DNA (deoxyribonucleic acid) profile on ...
