The Fragility of Genetic Code

Your entire existence is literally just a biological computer code running on sugar and phosphate.

It is wild that your DNA holds every instruction to build you, but it stays locked

in the nucleus like a vault. That is why you need RNA, the single-stranded

messenger, to actually go out and build the proteins. But here is the scary part.

One single typo in that code ruins the whole program. Take sickle cell anemia.

Just swapping one tiny letter in your DNA turns your blood cells from flexible donuts into rigid

sickles. One microscopic glitch changes your whole life.
