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 ...
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 ...
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 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 ...

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 ...
MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...
