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 ...

The mitochondrial genome of Trypanosoma brucei is uniquely organised as a kinetoplast, a highly complex network composed of thousands of minicircles and a smaller number of maxicircles. This structure ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

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 ...

Researchers have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than ...

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a ...

There are a variety of machines, consumables, and safety equipment needed to operate a molecular biology lab. And yes, for the vast majority of labs, purified salmon sperm DNA is one of those ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes.
