I find some of this very amusing. A genetic word doesn’t exist, all genes are expressed with 4 bases, but they don’t form words, as they only allow up to 24 possible combinations.
Putting them together isn’t that complex, some bacteria require just 180-ish protein coding genes with 160,000 base pairs and that’s a very complex life form already. In the lab as low as 60 protein coding genes can be useful for synthetic life forms and then we haven’t talked yet about the things such as viruses that aren’t life forms but still replicate.
