#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

So the start is always the same.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

To me, that is fascinating that all life starts with the same start.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

There's no other start code.

#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

So you sent the AUG to the cell that when that information arrives, the translation knows, all right, I got to start.

#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Function is coming.

Following this is a chain of information until the stop starts.

letter, you have multiple options.

So you say you have a code A, the second code can be another A. And even if you mess that up, you still can't rescue yourself.

So you can get, for instance, I'm looking at the lysine K, you get an A and you get an A and then you get an A that gives you the lysine.
