  1. Is there any concern that the plasmid with that antibiotic-resistant gene on it will spread when you let the E. Coli come into contact with other bacteria?

  2. Most people don't realize how modified lab-strain E. coli are. Here's the genotype for DH5α, the strain I've used the most:
    F– Φ80lacZΔM15 Δ(lacZYA-argF) U169 recA1 endA1 hsdR17 (rK–, mK+) phoA supE44 λ– thi-1 gyrA96 relA1
    These are all the modifications we've made over the years to make this little critter useable for a wide variety of applications.

    For example, if Alex had used wild-type E. coli (from the toilet seat at the museum, for example), it would have digested the plasmid with the GFP before it ever got introduced.

  3. This is similar to a lab I did with my bio class. It's really interesting and also a reminder that I need to get to studying for the AP exam!

  4. Its not easy to thoroughly impress me when someone conveys material I'm hardly able to understand. Yet another reason why I knew it was a good idea to subscribe to your channel.

  5. So what about the super resistant super E.colis that even colistine can't destroy, are we all lost? Would a simple cold kill me in the futur like it killed american indians in the past? Nature will take it's revenge isn'it.. Oh and can you make a video about Crispr? 🙂 I could watch your vids all day^^
