In this episode of Tiny Show and Tell Us, we cover exciting new 'living robots' called xenobots — made from frog cells with the help of a supercomputer — and what they might be used for down the road. Then we challenge how much "junk" really makes up "junk DNA" and discuss the regulatory sequences and other things our DNA codes for that aren't functional proteins.
