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

The heart of the cellular activities are translation.

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

You kill translation, you kill the cell.

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

Not only the translation itself, you kill the component that initiates it, you kill the cell.

You remove the component that elongates it, you kill the cell.

So there are many different ways to disrupt this machinery.

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

All the parts are important.

Now, it can vary across different organisms.

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

We see variation between bacteria versus eukaryotes versus archaea, right?

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

So it is not the same exact steps, but...

and get more crowded as we get closer to eukaryotes, for instance.

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

But you are still computing about 20 amino acids per second, right?

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

This is what you're generating every second.

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

21 for bacteria, I believe 8 for eukaryotes or 9.

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

I think it's great.

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

I think, if you can show me a computer that does this, we are done here.

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

Yes, you can show me that, but you cannot show me the one that has all.

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

For now.

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

For now.

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

I think the more we learn about, and this is why early life and origin is also very fascinating and applicable to many different disciplines, right?

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

There's no way you see this the way we just described it unless you think about early life and early geochemistry and earliest emergent systems.
