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

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

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, ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for 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 ...

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 ...

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 ...

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

Most cancer cells have genomes that are much less methylated than those of normal cells, but whether this loss of methylation, an epigenetic process, has any functional meaning for the cells has long ...

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 ...
