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 ...

A scientific team says it has pinpointed the crucial steps in the beginning of the DNA replication process, including surprising structural details about the enzyme that unzips and splits the double ...

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

An elusive step in the process of human DNA replication has been observed, for the first time, by scientists. The step, which is crucial for DNA replication in humans and other forms of life, had ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

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 ...

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 ...
