dCas9: CRISPRi CRISPRa CRISPR-ON CRISPR-OFF (Beyond Cas9 Genome Editing)

What is CRISPRi (CRISPR interference)? What is CRISPRa (CRISPR activation)? What is a dCas9 and how to use dCas9 for CRISPRi and CRISPRa experiments? dCas9 can be fused with effector domains to regulate gene expression for functional studies. In addition, you can extend the CRISPRi/CRISPRa based tools to build permanent epigenetic modifications using CRISPR-ON and CRISPR-OFF. In this video, I discuss the details of dCas9 based genetic manipulations (and multiple iterations/generations of these tools) used to repress and activate genes and go beyond genome editing using CRISPR/Cas systems.

Is there any lab in your knowledge which offers PhD position in core genetic engineering ?
Very educative description! Thank you!
Amazingly clear video, thank you! Just a small remark for you: it's 'foreign', not 'foriegn' :)
I love how you discuss these lessons, I am a bit of a visual learner and your videos help me a lot <3

thank you so much this is a lifesaver. i've been reading the papers on golden gate and your explanation is so helpful. seeing everything drawn out makes it much easier to understand!
I read a textbook for this topic and got massive headache. Then afterwards watched your video understood everything thank you. It was really helpful.
Is this explanation masters level?
Thankyou for the explanation

Very nice explanation!
Where is there an explanation for how this gene has a unique identification?

Is it beacuse the glucose from lactose is far from the membrane where adenyla cyclase is so it can enter glicolisis before reaching the membrane therefore the inhibicion is low, in the other hand when glucose enters thru membrane proteins it is very close to adenilate cyclase
Very well made and extremely detailed video! It helped me understand the topic better so I could explain it in a test. Thank you very much, greetings from Brazil!
Absolutely love your lectures, i have been reading genes by lewins along with the videos and i have to sometimes yours are even more detail oriented than them.
