Your Amazing Molecular Machines
These are the molecular machines inside your body that make cell division possible. Animation by Drew Berry at the Walter and Eliza Hall Institute of Medical Research. http://wehi.tv Special...
==========
These are tiny molecular machines, and they are doing this inside your body - right now.To understand why, we have to zoom out.Every day, in an adult human body, 50 to 70 billion of your cells die.Either they're stressed, or damaged, or just old. But this is normal - in fact, it's called "programmed cell death".But, to make up for all these lost cells, right now, billions of your cells are dividing,essentially creating new cells. And that process of cell division, also called mitosis --well, it requires an army of tiny molecular machines. So, let's take a closer look.DNA is a good place to start - the double helix molecule we always talk about.This is a scientifically accurate depiction of DNA, created by Drew Berryat the Walte...
