oh my God. i am from non-biology background. cannot believe our human has this jaw opening cellular dna mechanism. amazing how this was even discovered. thank you
Ap Endonuclease cleaves the 5’ end .. and Lyase cleaves the 3’ end .. then DNA polymerase and DNA lygase play role. You forgot to mention the Lyase part! “Base-specific Glycosylase removes altered base and creates AP site (apurinic/apyrimidinic). One or more nucleotides are removed by AP-Endonuclease, which cleaves the 5′ end. Lyase cleaves the 3′ end. DNA Polymerase-β fills the gap and DNA Ligase seals it. Occurs throughout cell cycle.” GEL PLease! (The steps gylcosylase, endonuclease, lyase, polymerase, ligase) The quote is from FA USMLE step 1, biochemistry section (2 section), page 40.
Your videos helps me a lot during my exams and makes easy to understand the topics short and very clear.. I really appreciates your hard work... Keep it up... Try to make videos in regarding to every concept in biology because some hard portions we are finding your videos... Once again thank you for your great work ✨
Today I got to know that u r from Kashmir...I was thinking that u r Pakistani,,...I am from lolab valley kupwara and I am studying outside state and your vedios has helped me a lot from previous few years....Love u bro and now I am much proud on myself that whatever I achieved, some credit goes to u also ....Love u man 😊...proud of uhh
One question though. How the DNA glycosylase know which base (in this case uracil), are the wrong uracil. After all, there are uracil also in immature mRNA. Why don't the glycosylase also cut the uracil from the right nucleotide? how it recognize the wrong uracil?
Sir you've deleted video on nucleotide excision repair ??? It was in your channel and i couldn't find it ..will you let me know you deleted or its there???🥺
Sir wil u plz make a video on reversion mutation?...it is complicatd, evn im nt undrstng why reversions r used to tst mutagenicity.... plz sir make me clear?😊
Hussain Biology sir is it possible tomorrow because I have exam ur previous lectures helped me in understanding the topic so I need for this also if possible
Hi Navita.......Yes i try to make advanced level videos and I hope you will find them useful for CSIR net.... My Channel is totally based on CSIR NET.....
@@ComandaKronikk Actually apyrimidine site is very rare since it requires high acidity to cleave off the pyrimidine from the site where as Apurine site is easily formed in the cell at lower acidity or even under neutral pH. that is why your Professor has told u it is mostly Purines.
90 percent of his audience is Indian so I don't think pronunciation is a major concern for him. Yes it is slightly off but it doesn't need to be perfect. It's still understandable for most of his viewers :)

Thank you for this CLEAR explanation!
excellent explantion! Thanks so much
THANKS HUSSAINNN !!! YOU ARE THE BEST !
Thanks Emila for appreciation...Glad to know that it helps.....
Video excellent bro,but voice is not clarity,make sure for that
Thanks for precise and clear explanation 🙏
You are welcome ✌️
Always been a big fan of your work.... Can you please do a video on Nucleotide excision repair?
i just want you to know that all of your videos are awesome... keep it up... and help us by making more clear videos like that :)
Glad to know that my work helps you and i really appreciate your words ........It really boosts my confidence ..... Thanks Ayesha 😊

Great 👍 first of all thanks buddy for appreciation .... and where from u got to know i am from Kashmir ?
@@hussainbiology comment sections se pata chala bhai ...thanks to you I almost topped my batch after watching your vedios ..
thank you! super helpful and clear!
T hank you
Thank you for this through explanation!
Do we have a short-patch and long-patch repair in prokaryots ? Is it kinda BER ?
Yeah….it is kinda a BER
One question though. How the DNA glycosylase know which base (in this case uracil), are the wrong uracil. After all, there are uracil also in immature mRNA. Why don't the glycosylase also cut the uracil from the right nucleotide? how it recognize the wrong uracil?
fantastic video, thank you :0)
you are welcome ✌️
Plz recombination repair topic pr video bnado sir..🙏🙏🙏
Haan jaldi
Superb explanation
Good one .
Thanks
Sir you've deleted video on nucleotide excision repair ??? It was in your channel and i couldn't find it ..will you let me know you deleted or its there???🥺
No no.. i don't think i have made a video on that topic.....
Ya toa mai he bhool gaya hoon
U r doing great...keep it up
Thank you so much 😀
Amazingly explained
Thanks Pranali for appreciation...Glad to know that it helps...
very well done mate
Thank you so much!!
Because of methylated cytosine converts to thymine by removing amino group and adding one h2o molecule
You didn't clearly explain the work of Ap endonuclease. DNA glycosylase removed the base... And what did the Ap endonuclease do?
AP endonuclease cut phosphate sugar backbone and create a nick
@@FOODIESWITHAQSA now i get it... Tq
great explanation
Thanku sir🥰
my pleasure... Glad it helps ✌️
do you provide any notes in any ur website or in pdf format...it will be really helpful!!!
Apologies.. the website is not functional anymore and as of now I don't provide any notes
@@hussainbiology its fine sir...the video itself was informative 🙂
I learned that from your one previous video
This video is awesome!
Thanks Sarah for appreciation.....Keep supporting 😊
Great work ... Keep it up...
WONDERFUL!!
Thanks dear for appreciation
Nice nice very nice
Thanks Mansha for appreciation...

I will definitely help you out.......
Hussain Biology ...advance thnks sir😊😊😊
Hussain Biology ...thnku sir fo sharing😊😊😊😊
My pleasure 😊😊😊😊
Vedio was helpful
Thank u
Thanks buddy for appreciation....
replication, transcription and translation
Sir u don't have nucleotide excision repair lecture video i need this
Apologies....
I haven't made a video on that yet but i will definitely consider your suggestion .
Hussain Biology sir is it possible tomorrow because I have exam ur previous lectures helped me in understanding the topic so I need for this also if possible
Sorry Hem.......It is not possible to make a video and edit it within few hours...
Hussain Biology ok sir
Apologies,,,,,Couldn't help
good !
Thanks Buddy....appreciate ur support
sir kya apki videos NET k liye b usefull hoti hain...?
Hi Navita.......Yes i try to make advanced level videos and I hope you will find them useful for CSIR net....
My Channel is totally based on CSIR NET.....
Hussain Biology thanq sir
You are welcome.....
Where is nucleotide excision repair???
Sr nucleotide repair ki video kb banaoge 2 sal ho gai
sorry what is AP Site?
apurinic or apyrimidinic site. Where Purine or Pyrimidine is missing.
@@hussainbiology I've been told by my professor that AP sites are strictly for missing purines
@@ComandaKronikk Actually apyrimidine site is very rare since it requires high acidity to cleave off the pyrimidine from the site where as Apurine site is easily formed in the cell at lower acidity or even under neutral pH.
that is why your Professor has told u it is mostly Purines.
I think the hydrolytic deamination results in cytosine to thymine not uracil
base excision what 😳
Rapier
you are from kashmir? I can tell from your sound..lol😁
Indeed i am Kashmiri...
which district? srinagar?
@@basharatali927 Baramulla Pattan
ok sir BTW I am a sheena dard from Gurez valley bandipora ..
That is great......Means i have now subscriber from Gurez also...,😊😊
❤❤
👏🏻👏🏻👏🏻
It's not gounine it's guanine.... correct the pronunciation Mr. 🙂
Apologies....i accept i am bad at pronunciation but the point is... u understood still
Plz teaches in Hindi
your pronounciation is a bit of. You pronounce repair as rapier. Good pronounciation is like r eee p eehhhhh r.
