DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

“The biology professors at Caltech and elsewhere told me that ... Ten copies of the scaffold strand produce 10 DNA origami structures if there are sufficient staple strands. Recently, Shih’s research ...

Researchers harness the power of the world’s most advanced supercomputers to simulate the inner workings of cellular ...

Scientists have provided the most detailed account yet of the earliest stages of DNA replication, an essential process for ...

Thus, in her experiments, McClintock observed several fundamental properties of chromosome biology ... replication, DNA polymerase and the DNA repair enzymes fill in the other strand.

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Scientists have captured the first detailed 'molecular movie' showing DNA being unzipped at the atomic level -- revealing how cells begin the crucial process of copying their genetic material.

“It’s especially hard when we’re dealing with DNA mixtures,” said Julie Sikorsky, a forensic scientist and manager of the Palm Beach County Sherrif’s Office Forensic Biology Unit ... “Our hypothesis ...
