A system once tied to DNA organization in cyanobacteria has evolved into a structure that shapes the cell itself. This shift ...

DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes.

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of ...

Researchers are gaining a new appreciation for the genes on the X and Y chromosomes and how they shape sex differences in ...

Scientists have captured the most detailed structural images to date of a specific type of protein's DNA repair process, a ...

Arthur Kornberg compared DNA to a tape recording of instructions that can be copied over and over. How do cells make these near-perfect copies, and does the process ever vary? In reality, the process ...

A single DNA letter, inserted into a stretch of the genome that doesn’t code for any protein, was enough to turn genetically female mouse embryos into anatomically male mice. The experiment, published ...

DSB, DNA double-strand break; TALEN, transcription activator-like effector nuclease; ZFN, zinc finger nuclease; CRISPR, clustered regularly interspaced short palindromic repeats; Cas, ...

This video explains how DNA shapes the characteristics of living things. DNA is a long polymer that carries genetic information, arranged into pairs in structures called chromosomes. These pairs ...
