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 ...

Exactly how does the DNA replication process start? USC scientists provide the first snapshot of how double-helix DNA begins to unwind and replicate after certain proteins put on the “squeeze.” A ring ...

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...

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 ...

Researchers have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than ...

Researchers have identified the mechanism used by the helicase ring to thread around and separate entwined DNA strands in the replication process. DNA replication is a complex process in which a ...

DNA, or deoxyribonucleic acid, is the biological molecule which contains the information needed to create a living organism. As the cell divides to become two, the DNA has to be copied so that both ...
