The Common Genetic Code Released from Hydrothermal Environments[Previous Episode Summary]Inside the membrane, the gears of ...

Every time a cell divides, it must accurately copy its entire genetic instruction manual. Before this process can begin, cells load their DNA-copying motor—a complex of six subunits known as the ...

During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a connector ...

At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, ...

More than two decades after scientists first sequenced the entire human genome — all 3 billion “letters,” or base pairs, of DNA code — the meaning of much of this code remains a mystery. While an ...

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 ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

Did you know that many of us have up to 4% neanderthal DNA? Did you know that many of us have up to 4% neanderthal DNA? And that 100% of your DNA may come from outer space? No joke. The biochemistry ...
