There are actually only 20 different amino acids. Most of the codon sequences for DNA do not produce amino acids or are start/stop codons for the process of DNA replication and protein synthesis as such.

there are 20 different amino acids. That's all that's needed to create life!

Although it is true, that proteins are built of amino acids in certain order, directed dy DNA, they are not the only "key" to life. if you meant to ask how many amino acids do we need to function properly=survive, then the correct answer is 20. we can produce only ten of them ourselves. other ten are called essential because we get them with food. Some consider only 8 (or even 4) to be essential, because some of them are crucial for kids and people with different metabolism only. But most cases the number is 10.
Life(Dna more accurately) is built of nucleic acids. for more in formation check en.wikipedia.org/wiki/DNA

Just to correct BT's notion, there is no such thing as a 'unit of sound' and the atom has not been reduced to such a thing. I'm not sure where you might have read this, but it's not only not science, it's kind of a daft notion. Sound is a perception we have of the vibration of the atmosphere around us, it is not a thing like a photon of light or drop of water. As for the original question, we've most certainly done so. We've even done it in space.

amino acids? I would think you need a sperm and egg?
