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 ...
At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, particularly in tissues such as the bone marrow, intestine and skin; neurons and heart ...
Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this happens, your entire genetic library—your genome, which totals more than 3 ...
Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...
The Okazaki Fragments That Solved the Mystery of DNA Replication1. The Mystery That Could Not Be Solved by the Discovery of ...
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 ...
Not all DNA looks like the familiar double helix. Sometimes, parts of our genetic code fold into unusual shapes under certain conditions. One such structure known as a G-quadruplex (G4) looks like a ...
As DNA strands ravel and unravel in an intricate dance, one notable event takes center stage: replication. This process is essential to life, but the finer details of its orchestrated steps are still ...
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 ...
