Scientists reveal a hidden second layer of human DNA, showing how genome folding controls genes and influences disease development.

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...

The human genome has to be carefully organized so it will fit inside of the nuclei of cells, while also remaining accessible to the cellular machinery that works to express the right genes at the ...

Plasmids, small circular DNA molecules found in bacteria, may contain antibiotic-resistance genes and have the ability to replicate independently. Bacteria can transfer these plasmids to one another, ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Maize serves as a vital model species for advancing our understanding of plant biology, yet many mysteries remain about the ...

DNA is often likened to a blueprint. The particular sequence of As, Cs, Gs, and Ts in DNA provides information for building an organism. What’s not captured by this analogy is the fact that our DNA ...

Diagrams: Short section of DNA, 1951 -- Chemical structures of the DNA bases, 1951 -- Covalent bonds of the sugar-phosphate backbone -- Schematic view of a nucleotide -- Mg** ions binding phosphate ...

DNA, or deoxyribonucleic acid, is the hereditary material found in nearly all living organisms. It carries the genetic instructions for the development, functioning, growth, and reproduction of all ...

One of the most important milestones in modern science, does April 25 also mark the date of an intellectual heist? As has been well-documented, a third person contributed to the discovery — the ...
