Researchers at the University of Bristol have caught DNA-copying enzymes generating long stretches of genetic code without any template to guide them, a behavior the team calls “doodling.” Published ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and collaborators have uncovered one of the earliest steps in DNA replication: the moment a cell first opens its DNA to begin making a copy ...

Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a discovery that could ...

Scientists have captured the first detailed 'molecular movie' showing DNA being unzipped at the atomic level -- revealing how cells begin the crucial process of copying their genetic material.

Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying "mistakes" account for nearly two-thirds of the mutations that ...

In turn, this slowed new DNA synthesis at replication forks, structures in which double strands of DNA separate to begin the copying process. The cells' attempt to restart the stalled replication fork ...

GALVESTON, Texas — Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a ...
