Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...
When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...
When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...

A protein thought to play a supporting role in DNA replication actually facilitates the whole process
Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
Patients with this genetic disorder have a form of dwarfism — they are short in stature and have underdeveloped ears and ...

A new study has discovered in mouse models that genes associated with repairing mismatched DNA are critical in eliciting damages to neurons that are most vulnerable in Huntington's disease and ...
