This Experiment First Cracked the Genetic Code—But Most People Have Never Heard of It

One of the most important experiments in the world manages to fly under most people’s radar. After years of patient experimental work, two scientists managed to figure out how one code in DNA translated into an actual, physical protein.

It’s nice to see a headline on the net not confusing the genetic code with the genetic sequence. Only the latter is something akin to the source code of computer science, whereas the former governs how genetic information is translated into proteins.

What Made the Y Chromosome So Tiny?

The Y chromosome, a chunk of genetic code that is unique to male animals, isn’t just physically smaller than the X. It also contains far fewer genes. The X has more than 1000 genes, while the Y has fewer than 200 —and most of them don’t even work. Why do men have this odd, stunted chromosome in their genomes?

Some animals already have lost the Y for good. And yet, they keep having male offspring. How? Nob0dy knows yet.
