If we can create organic compounds from inorganic substances, why can't we just create DNA, cells, life from scratch?

They can make DNA from scratch. But even if it wouldn't take too long to make all the components of a cell, how would they assemble it all together?

If we can create sheets of metal from their ores, why can't we just build a Dyson sphere around the sun?

Well if you make a bunch of lipids, won't they automatically arrange in a bilayer, then you can just stick everything inside? I dunno, lol. So the answer is that it's too complicated?

>> No.2361670

>>2361642
Because the complexity requires tools and knowledge we don't have yet. Genomes can be created from scratch, geneticists can take a computer and bases and enzymes and make a genome. J. Craig Venter's research team recently put a genome constructed from scratch in place of the existing genome in a bacterium. But, cells are not simple things. They're packed full of organelles, there are over 4000 different reactions being catalyzed at once with over 40000 different compounds at once, and cells tend to die one they stop.

Make dna. Make proteins using dna. Make life. http://en.wikipedia.org/wiki/Protein_biosynthesis

It's allot of work but seems like we could do it.
Real question is why bother.

You identify and make the most simple cell, like a bacteria or fungi. Use that cell to be host to auxiliary orgenells which will be transplanted to your final cell.

The second things you should make is mitochondria and midichlorian. Then fill in the bare minimum to get a viable ovum and vwala you created life from scratch.

There already is bacteria who can hibernate in space. We must only modify them so that they can actually reproduce in space.

Well we can, and it has been done.
However, it's a shit ton of work and you can't really do anything but copy nature's work, because coding a lifeform from scratch is near impossible at the moment.
Imagine trying to create a CD full of information by just typing a big line of 1's and 0's.

we can. Provided the right elements combined with electromagnetic waves. You get yourself organic elements. Provided millions of years you get DNA. Sweet. This has no practical application except the slow development of life /thread

>why can't we just create DNA, cells, life from scratch?

We've created DNA from scratch, but the code is largely nonfunctional because we don't understand all the interdependencies yet.

We could probably make cells since their constituent lipids and proteins are largely self-assembling, but there's no point until we can make some functional DNA to keep the biomachinery running properly.

>> No.2363887

>>2363845
Well, suppose you have, and you construct a perfect strand of mammoth DNA. Then what? Obviously, your petrie dish is not going to sprout a prehensile trunk. I don't think we have a functional method (or even theory) for going from a DNA strand to a blastocyst.
