What does our DNA really look like?
You might imagine DNA as a double helix or a sequence of letters but what does this incredibly long molecule actually fit inside our cells?

So how does something so long fit inside a cell without being a tangled mess? Carl Zimmer from Science Happens! speaks to Job Dekker about our inner origami.
