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 ...

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 ...

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 ...

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 ...

At each cell division in humans, DNA replication starts from 50,000 DNA replication origins, which are at specific locations along the chromosomes and from which DNA synthesis proceeds bidirectionally ...
