Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...
A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...
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 ...
For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already ...
In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...

Human DNA just stopped mutating. Here’s how it ends us
Your DNA is constantly changing. And if it weren’t for genetic mutations, evolution wouldn’t exist. So, what would life be ...
Seventy years ago, two male scientists, Francis Crick and James Watson, proclaimed they had discovered the secret of life: the structure of DNA. Since then, history has acknowledged how Rosalind ...
In May 1952, Rosalind Franklin and Raymond Gosling captured Photo 51, a crucial X-ray diffraction image revealing DNA's ...
