The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

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 ...
Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists ...
DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells use ...
Scientists show DNA polymerases can build long, patterned DNA without a template, opening new paths for synthetic biology and ...
Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

DNA-copying enzymes caught making errors that could reshape DNA writing
Researchers at the University of Bristol have caught DNA-copying enzymes generating long stretches of genetic code without ...
Drs Ursula A. Matulonis and Joyce F. Liu discuss targeting DNA damage and repair and replication stress in endometrial cancer. Drs Ursula A. Matulonis and Panagiotis A. Konstantinopoulos discuss ...
A cancer drug target already being investigated in clinical trials turns out to be doing something even more consequential ...
