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)

[@aakaankshavangala1826]

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.

In the results interpretation part, you appear to be removing even terminal nucleotides (like you removed the C from the T+C tube). Didn't you say that the terminal nucleotides cannot be removed ? Also in what manner are the nucleotides being fragmented ? There should be atleast 4 different types of fragments in the G tube for example if we remove the G from the middle.

[@aimalkhan385]

infact it is helpful. Great.

Please what is the name of the referenced book, how do we get it

yes plz

How can you identify A at Terminal 5 prime end. As it shows the band in T+C.

[@mariyummariyum48]

[@prempratyushmangraj1050]

Sir.. How can we know about the first nucleotide?

[@kavitachoudhary6168]

Sir I have a question As we can see that while chemical degradation sequence is cleaved at the site just before to that perticular residue so what about A which is radiolabled as a first residue. How we will know that A is present at first becs when it get cleaved we will get only phosphate without sequence?
