Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies ...

A team has published pictures at very high atomic resolution of the multi-part protein complex that performs the very first step in the incredibly complex genome-replication dance that occurs when one ...

Unlike nuclear DNA, mitochondrial DNA (mtDNA) is circular in nature and organized as mitochondrial nucleoids comprised of DNA-protein complexes that are distributed in the matrix. It is also inherited ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...

Genome duplication must occur before cell division, so that both progeny cells inherit a complete copy of the genetic material. DNA replication is initiated at particular chromosomal sites called ...

DNA: It's what makes you unique. Unless you have an identical twin, your DNA is different from that of every other person in the world. And that's what makes DNA fingerprinting possible. Experts can ...

In experiments with transgenic mice, University of Pennsylvania School of Medicine researchers discovered the remaining steps in the complicated process of how the largest class of jumping genes ...

Cold Spring Harbor, NY - It's a good thing we don't have to think about putting all the necessary pieces in place when one of our trillions of cells needs to duplicate its DNA and then divide to ...
