Its a good try, but there are few things which has to be dealt for better understanding like: 1. what chemicals are used specifically to cleave a certain nucleotide (G-DMS, A-Formic acid, C-Hydrazine+NaCl, T-Hydrazine) together with piperdine to cleave the phosphodiester bond of modified nucleotide 2. How to make single stranded DNA fragments (heat denaturation or using helicase) 3. Dimer formation are in combinations of A+G and C+T If a band in the DNA sequence appears in both the G-reaction and the G+A-reaction lanes, then that the nucleotide is a G. If a band in the DNA sequence appears only in the G+A-reaction lane, then it is an A. The same decision process works for the C-reaction and the C+T-reaction lanes. 4. What quantity of sample DNA is required for sequencing (if not sufficient, have to run PCR or do cloning to amplify) 5. What about the left part of DNA strand after cleavage (they cant be visualized, due to lack of isotope) 6. What percentage of gel is preferred (6% polyacrylamide gels are used, bcz they are too sensitive in differentiating the DNA bands with 1bp size)
I'm doing an essay on genomic analysis, and these videos on sequencing are amazing for a proper, scientific understanding of how sequencing has developed over the years. Thank you so much for the clear and helpful video!
I am a veterinary student .....GADVASU....number one veterinary university in india......still we dont have any teacher like u sir......thank u very much❤️❣️
no need for short videos....you are doing great job... because it is helpul for begginers,,,if you start to make short videos ...then the beginners will not understand....thanks alot...very helpul.....
when you write down on board that method is good for understanding and due to only this difference between you and other you tubers i was watching your videos
Iam so happy that you replied to me I have used your site to undertand concepts for my molecular biology masters degree. At Makerere university Uganda… thank you we appreciate your efforts to teach the world science
Awesomely explained. This is my first video on Maxam-Gilbert, n you cleared the concept seamlessly. I won't go into technical details, I will just say that concept-wise this lecture is awesome. :-}
@@shomusbiologyofficial,your class is really helpful, sir you take an example of 12 nucleotide, and in autoradiography in the 11th portion the 12th nucleotide come..can you please explain it
thank's very much now I depend on you very much to understand any thing .I wish I Can reply the favour ❤❤ and please don't stop many students depend on you . Marwa from egypt
1. Not Chemical Synthesis. It is Chemical Cleavage (two completely opposite meanings) 2. First nucleotide determination without which DNA sequencing is incomplete. From my understanding, you are supposed to initially cut/cleave the DNA sample with a restriction enzyme. From this you get to know where the DNA is getting cleaved (as you know the restriction sequence of the enzyme). This is then followed by the steps explained in the video.
Thank you so much sir. Your teaching method is very easy and very helpful for understanding. Sir please make a video lecture on Evolutionary Game Theory.
plzzz sir explain this in black board . its a humble request from my side because i saw this explanation in black board on many other u tube channel's. but for me sir only u have abality to explaining in black board with ease. otherwise this presentation is also very good sir👍👍
At 1 guanine reaction ,u told that DMS will cleave the guanine ,so no stretch of DNA will form . But how it produce 3 types of strand at guanine reaction ,because DMS will break sequence ,so we will get same type stretch DNA only sir ,???
First of all, how do you get fixed length of dna strand, second, how many fragments will there be in the test tube. Thirdly, when the string is cleaved, what happens to the left part of the string. If that dissolves then why not the right hand part dissolves.?

Praveen Kumar you are stunning.help me a lot
hello friends
Praveen Kumar Thanks
Thanks
thanks
I just realised that I've been passing my entire uni thanks to you but never said a proper thank you so: Thank you! (=

I came across this video , and may i say you are the best youtuber teacher we have got
Hands down sir, you are brilliant

+Ejaz Khan thank you.
My best BIOLOGY teacher over whole youtube
Thank you so much for appreciating my efforts
@@shomusbiologyofficial Love From Pakistan
when you write down on board that method is good for understanding and due to only this difference between you and other you tubers i was watching your videos
This is so helpful but I almost got confused at the initial result interpretation but thank God, I later understood it.
Thank you Shomu Biology
You're welcome
Interesting and very clear explanation. don't bother about the time because it's very interesting and understandable. Thanks shomu!
Thanks for this video. It's really helpful for me.....This topic is in my syllabus....thanks a lot
You're welcome
Thankyou sir.....you re the best teacher...😍
you have a simple way in teaching and presenting the idea
Thank you. Glad you liked my lectures
indeed its helpful...........complicated topic bt after watching twice /thrice i can understand for sure..
+Alwina Anam thank you very much
Great sir very easy and understanding english best method of teaching 🇵🇰

but what about the first nucleotide ? how to know it?
Thank you soo much professor 🙂

Cysteine.....😅 repeated twice lol
But nice explanation as always your videos are helpful keep it up👍
Great...... Thank you

amazing video
Thank you
Awesome. It helped me a looooot. THANK YOU
Thank you very much Sir. It helped me a lot
You are the best💜💜💜
thank you...
great explanation...
Thnk u for helpful explain
You're welcome
waah sir...lovely...very easy
thank you bro i got help from this video..
keep it up
Thank you
great explanation. thanks :)
extremely helpful!!!
+samjhana stha thank you. Glad you liked my lectures
doing a great job man (Y)
Sir please do video on edible vaccines it is very useful for us.
Okay
I love this guy
thanks for your explain
Thank u so much.. really helpful
+Suprita Dash Glad it helped
diagram is from which book? a good informative video!!!
you are AMAZING
Thank you so much SIR
simply awesome!! got it :)
infact it is helpful.
Great.
Great work
The last step is quite complicated. ..
Awsome great work love you
Thanks♥
You're welcome
Sir it was very helpful but how A is the 1st nucleotide is not I think explained
Thanks a lot.
Thanks alot👌👍
Thank you
You're welcome
good lecture
Good job
And what about first base Adenine...gel doesn't have this info.. so whats the reason sir..plzz...tell us
Thank u very much
Thank you sir
Thank u
You're welcome
THANKS U SIR TO INFORMATIVE
How did you know that the very first base in the gel is Adenine?? Someone pls answer
May Allah please uuuu😍😍
Thank you
thanx a lot
How can you tell the first nucleotide is A(adenine) from electrophoresis? Please answer
yes plz
That sorry got everyone's attention 😂
thank u so much!!!!!!!
Like many others I also want to know whether 1st base can be detected correctly from this method or not.......if not why
How can you identify A at Terminal 5 prime end. As it shows the band in T+C.
I have understood all but why shoud we underline some particular sequences
Sir.. How can we know about the first nucleotide?
At 1 guanine reaction ,u told that DMS will cleave the guanine ,so no stretch of DNA will form . But how it produce 3 types of strand at guanine reaction ,because DMS will break sequence ,so we will get same type stretch DNA only sir ,???
Nice video man, what are u studying? :)
just good
Please what is the name of the referenced book, how do we get it
Sir why we Have To elute out the heavier band and work with only the lighter band after the denaturation of DNA double-strand??
Please reply sir
Sir can you recommend books related to life science
Campbell Biology
First of all, how do you get fixed length of dna strand, second, how many fragments will there be in the test tube. Thirdly, when the string is cleaved, what happens to the left part of the string. If that dissolves then why not the right hand part dissolves.?
It will be much better if you explained in urdu or hindi...
why the first base (A) is not identified..?
