This is the most accurate model yet of what DNA looks like
This is a stunning 3D map that shows how six feet of of DNA can be crammed inside a single chromosome — a space that’s only a hundredth of a millimeter across. Not surprisingly, it looks like something that would go well with meatballs.
Chromosomes, those packages of genetic material found in our cells, were discovered way back in the late 1800s, but scientists have struggled to understand the exact way DNA molecules fold into them across three-dimensions. But a new study conducted by researchers at MIT and the University of Massachusetts Medical school has resulted in the world’s first comprehensive model of the 3D organization of condensed human chromosomes.
