Great question. In almost all cases, you have an actionable lead after doing a screen experiment. The problem is typically that you have learned too many, not too few things. And those things need to be backed with more experimental evidence.<p>But more generally, the iteration latency is about a week to order &amp; receive reagents for another targeted screen. Or if you want to do a single gene CRISPR experiment, you can get the single oligo reagents the next day.<p>Then the cloning, virus production, cell infection, etc. will be about another week if you are rushing.  We in genomics are still a far cry from the iteration latency in software dev, but given that many of our scientific forefathers&#x2F;mothers in the previous generation counted on making a whole genetically engineered mouse (which could take a year+) for an experiment, we&#x27;re making solid progress.<p>More questions about the real world lab experience are always welcome!
