A team has unlocked a decades old mystery about how a critical cellular process called DNA replication is regulated. A team of Florida State University researchers has unlocked a decades-old mystery ...

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 ...

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 ...

Multicellular organisms (animals, plants, humans) all have the ability to methylate the cytosine base in their DNA. This ...

BERKELEY, CA -The molecular machinery that starts the process by which a biological cell divides into two identical daughter cells apparently worked so well early on that evolution has conserved it ...

Researchers from Karolinska Institutet have discovered how mammalian cells prevent the gradual buildup of harmful mutations ...

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 ...

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 ...

The radiation in space is not great for biological health. Space radiation is known to damage DNA. Many types of human cells have to frequently divide to replace cells that are worn out, old, or ...
