I came across this gif (hopefully it’ll show up) of how RecA works! RecA is an Ecoli protein which among other things catalyzes the formation of chiasma during replication and repairs damage that occurs during recombination. Defects in the protein can cause DNA damage, and weird recombination (which I discovered the hard way when I was cloning). Anyway, I thought the gif was cool!
Edit: The gif works if you click on it!
Hahaha, technology at its best!
