When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...
Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...
DNA, which has a double-helix structure, can have many genetic mutations and variations. Credit: NIH When cells in the human body divide, they must first make accurate copies of their DNA. The DNA ...
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 ...
New research shows hydroxyurea reshapes DNA replication in cancer cells, revealing stress responses that may help design ...

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 ...
PHILADELPHIA – When cells in the human body divide, they must first make accurate copies of their DNA. The DNA replication exercise is one of the most important processes in all living organisms and ...
