Our body's cells repair DNA
If you could look inside one of your body’s cells, you would see hundreds of tiny machines, called enzymes, constantly running up and down the long DNA fibers that make up your chromosomes. What are all these enzymes doing?
Some are busy reading the genetic information and sending out instructions (via messenger RNA) to ribosomes telling them how to build proteins. Others are constantly monitoring the state of DNA looking for any damage. When damage to DNA is found, enzymes quickly team up to fix it. In our laboratory, we study a type of enzymes which can rejoin together the ends of broken DNA fibres.
