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 ...

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 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 ...

It has long been accepted that a gene's protein-coding information is contained in only one of its two DNA strands. But in 22 February Nature, Victor Corces and co-workers at the Department of Biology ...

New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought. Half a century ago, scientists Jim Watson and Alexey Olovnikov ...

Half a century ago, scientists Jim Watson and Alexey Olovnikov independently realized that there was a problem with how our DNA gets copied. A quirk of linear DNA replication dictated that telomeres ...

Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division - a discovery that could lead to new cancer therapies, according ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies published in the journals Science ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...
