thank you very much i had been strugling with these and my project is involved with lncRNAs, i had no idea about its function and regulatory, i should say realy thank you becouse of your usefull vidoes and your great way to explain it to me❤
This is excellent 🤩
A very well explained lecture! Thank you so much!
Cool explanation. Thank you for updating us on methylation. According to your talk depending on the region hyper methylation can be repressive in some regions for gene expression. But not for some others?
I just want to keep listening to her, very comprehensive and clear!
thank you Professor Blewitt, for your great coverage of a very incompletely understood branch of science.
I am preparing for MCAT and finding tons of important knowledge here.
Thank you this was really really helpful and simplified, keep making more content it’s really helping especially for university students ❤
Boring
Is it known how Xist transcription is initiated on one x chromosome but not the other?
Wow, that was a great explanation. Thank you. I read somewhere that inversion is the main cause, do you think it is wrong cause you said translocation somewhere in the video
thank you for these informative videos
Thanks. Going to check out the rest of these
Excellently explained, thank you!
XCI or XIC? X-Chromosome Inactivation? or X Inactivation Center?
x inactivation center
Marvellous video, thank you for making it reachable 🙏🏼🙏🏼💕
So the relation between lncRNA and miRNA is inverse proportional in the same disease usually,right ??
very helpful
what's the diff between chromitin and nucleosomes in definition???
A nucleosome is the smallest subunit of chromatin,formed by dna wrapping around an octamer of histones, dna being the string and the histone being the bead. Nucleosomes folding over each other condense form a more condensed complex of dna and proteins called chromatin, and chromatin condenses further to form chromosomes.
Did not even give the full names of of her abbreviations!!! Not a good teacher!!!
DNA methyltransferases can catalyze C to U and 5mC to T deamination.
I love the brain of this woman.
just want to clarify that there is an exception regarding methylation of Cpg islands where methylated islands can cause transcription only in case of igf2 gene
Excellent videos
Thank you mam
So am I right in thinking that piRNA are to transposons what miRNAs are to normal mRNAs?
Thanks, Your lessons have made me love Epigenetics so much. I use them for personal reading and I find them easy to understand
read cathy ennis epigenetics!
I think it's awesome that contemporary biologists are able to draw conclusions about epigenetic regulation just by looking at the karyotype.
THIS IS THE MOST IMPORTANT VIDEO EVER, CAREFULLY PAY ATTENTION TO EVERY SMALL DETAIL IN THIS wow I watched this when this was on coursera and promptly forgot everything, until a thiel fellow refreshed my interest
does iPSC reprogramming decrease activity of repressive chromodomain proteins? Do repressive chromodomain proteins maintain differentiation? Also are chromodomain proteins more pro-longevity (keeping chromatin compact) or anti-longevity (potentially inhibiting translation of longevity-important genes like glycolytic ones)? [bromodomains rely on acetylated/open histones and are more pro-cancer/anti-longevity. with chromodomain proteins that rely on histone methylations, it seems way more complicated] (edited)
Nicely explained👍
Thank you very much. I get a lot of trouble understanding my own professor, so I find your lectures simplified and more understandable
Superb
:0
Thank you for this video!!
I am overwhelmed about how much stuff is going on in the cell,,,
SUPER HELPFUL!
Which regions of X chromosome are inactivated?
Very nice ma'am, can you provide reference review article for this!
Awesome explanation, thanks
is your relative from nepal
are you really a durga limbu ?
Thanks mam!!!
Thanks for explanation! !!!
Well explained mam...thanks!!!
Nice explained mam...thanks.
Thanks
nicely explained :)))
Very confused explanation, in last lecture she said, DNA methylation occurs at CpG island, in this lecture she said DNA methylation does not occur in CpG island, it occurs in intergenic region. And she often uses" probably," "it seems".......
The CpG islands are largely unmethylated, methylation occurs in other sites
I think she just mentioned that methylation in CpG island is less compared to intergenic regions and repeat sequences.
