F215 OCR A2 Biology - Genetic Engineering + Insulin

I cover Genetic Engineering, all the enzymes used, how DNA is extracted, and how cells are modified to produce insulin protein.

Your videos are so good! 5 star quality. I love them because I can listen I don't have to watch. I just wish there was more for unit 5

A2 Biology in less than 48 hours, and here you are Jack, saving me .. thanks alot bro ..

[@benii7994]

Thanks Jack, Your videos are so clear! Just wondering if you'll be doing more videos on the other topics in F215? It would be so helpful if you'll be able to do a video on Gene interactions( Epistasis,codominance, genetic Diagrams and the Hardy-weinberg Principle Please :)

This video is sooooo useful, didn't understand replica plating but you made it soooo easy Thank you !!!

[@zannatul23]

Thank you bro, great video with succinct explanation

[@BenH1506]

Really helping these mate, do you think that you will have most topics up before the exams?

[@letdein]

Your videos are all really helpful thanks, and i presented well but as some constructive criticism a little bit more editing wouldnt hurt. Just in parts such as 1:20 where you repeat things so you can get back into the flow just editing out those bits ive noticed in 1 or 2 other videos - but it doesn't detract from the quality of information which is great

How is the insulin extracted afterwards?

[@SamiraOfficialx]

this was really helpful! thanks for posting.

[@gracenatalie1245]

These are amazing, are you making any more 215 please????

[@bughsoftheworld]

bloody brilliant, thanks !

[@KrishnaSharma-nr8fo]

Hi Jack! Thank you so much for this video, it cleared a lot up for me! I was wondering though, if they die in tetracycline, how do you use them to produce insulin, because they can't reproduce and/or produce insulin if they are dead? Thanks again :)

[@zannatul23]

you trace back to the colonies that died, and u basically find out the original colonies used if that makes sense

[@jessgarrett2996]

Thanks for the video! Do you think you could explain how you would then go about collecting the bacteria cells with the recombinant plasmid?

[@abhaysoni9588]

Thanks Jack, soooo clear!

[@AM-xz2py]

Thanks for the video, could u pls do a video on the sliding filament model?

[@tejiricoker8445]

Really helpful Thank you

[@EpicEditsBySaz]

Thanks for the vid. But could you please get rid of that reflection? Maybe place a really thin piece of paper over that light?

[@JackALevelTTC]

Yea man it was a rainy day lol, I'm sorry :( if I don't have the light on the board is too dark to see

[@studyunderstandteach6892]

Hey guys.. Check out my page for A Level Revision slides on Physics Chemistry Biology and Mathematics.. more videos upcoming!

[@ellieismad4music]

calcium salts make the membrane more permeable

Mitigates against the existing electrostatic repulsion between cell membrane and dna

[@milknosugar8773]

anyone else cramming for bio tomorrow lmao

[@JFD99BAD94]

yeppp

[@ARa-gq2sd]

Yeah. And dying.

[@EpicEditsBySaz]

I'm so scared for Wednesday and its not even a pm exam :( I've got so much content to cover...

[@LifeWithChiktaaay]

EpicEditsBySaz you and I both! But morning exams are better I feel - less time to freak yourself out. Good luck anyway!

[@EpicEditsBySaz]

LifeWithChiktaaay You too bro, hopefully we do decent, iA.
