It's like a blessing in disguise Sir.I'm a student of BS(Hons.) Zoology Department, actually i was searching BLAST for my presentation ..i did not found it in a precise way..finally a day before my presentation ,i found your lecture. i hope it would help me tomorrow ..Thank you very much..you did a fantastic job..keep it up Sir...
Great sir, This video is so helpful for me....can you make the video on " interpretation of the clustal omega results (alignments, result summary, phylogenetic tree [ real ]. I need of this video till Sunday 🥺...please can you make sir. I will be very thankful to you 🙏
Assalamualaikum, i have a query. Im using a BlastN for specie identification, but the confusion is when i run a sequence it shows different species from a same genus with a same percent identity, same query coverage and score, but its taxonomy shows inversely proportional scores and no of hits, so im trying to figure out what to prefer in this case? I hope you would get my point and guide me.
There is one question, that keep on pinching me; can't query coverage be defined as a factor which describes the homology or evolutionary relationship between two sequences. as you mentioned in the class that it always must be 100.... which according to my understanding actually tells weather or not they are homologous to each other.

Which one is more significant when comparing sequences for its function prediction....E value or identity % and why How much E value can be considered significant?
Hello Sir, I need more clarification on how to run blast and phylogenetic analysis. I have my sequence result from 4 18S rRNA isolate. I run blastn and all the 4 isolate have 95+ percent identity with previously published sequence/ species in the NCBI which is C.parvum. other published species showed lower than 95+ percent identity and when I run phylogenetic tree some of the isolate attached to Cryptosporidium tortoise instead of C. parvum that showed higher percentage identity. How do I interprete phylogenetic tree ? What do I do to identity species from my sequence result and do I deposit my sequence result to NCBI to obtain my sequence assertion number ? Thank you
in case of new strains similarity would be less than 85%? and can we claim based on these result that' it's new starins ..( I am referring fungal starin here ) or we need to go further gene analysis ,please guide about it if you can ?thanks
NICE LECTURE ,i, m a research student , few quereies like i hv result of my query seq from ncbi blast which shows 86.88% identity ,so is it ok. further i hv wgs results of a bacteria,in which i wanna go for pathogeny island prediction for which i was using PAIDB v2.0.cn u pls help me how to use tht particular software??
How to determine that first organism will be selected for further analysis if there were first 5 organism have identity at 100%....and max score,total score all are same....sir please elaborate this....
Aslamualikum Sir thanks for these fruitful lectures, but i m facing a problem in using the NCBI blast where in my system only description showed in detail, while all other option showed nothing like graphic and so on. If possible plz reply i m thankful to you sir forever. Regard Mohd Awas (research Scholar) University of Kashmir india
sir I have all the results are almost 100 % , the sequence i used was from GenBank. where I did mistake ? any idea? nucleotide was Saccharomyces cerevicae S288C (PPQ1). And your lecture is very informative,Thanks!!
Sir I see a option in BLAST where it shows it can compare two sequences and we get results. From there we can have the variant point but if i want to compare more than 10 sequences to find out the variation point then how it can be done. You know, from blast we can detect the variantion point of two sequences but if i just count and then place it in my paper it’s possible a mistake may happen. As i want to work with 50 sequences, it’s diffcult to run blast everytime and count them. please let me know if any Software or easy solution is available. Take love from Bangladesh. Thanks in advance.
sir, kindly ye btain k cancer genes r healthy person k genes kasy download kar skty ham ??? NCBI sy cancer k to mil jaty but healthy person k ni mil rahy mujy.
VERY INFORMATIVE VIDEO. Sir, i have the sequence result but when i use blast the similarity is different in term of organism name as well as the gene. is that possible? kindly advice. thank you.
The bit score, S', is derived from the raw alignment score, S, taking the statistical properties of the scoring system into account. Because bit scores are normalized with respect to the scoring system, they can be used to compare alignment scores from different searches.
Good evening Sir...I have made mistake in gene bank submission.I have to write in the data isolate instead of voucher specimen.Can I edit my gene bank records ...please help Sir..

The method is same as you submit your sequence on NCBI GenBank. You need to sign in first and then there is a submission option. You will submit your sequence there and and a specific accession number will be allotted to you.

waslam just follow identities and coverage not max score
Which one is more significant when comparing sequences for its function prediction....E value or identity % and why
How much E value can be considered significant?
both and E value should be 0 or less than 0
Great sir. Your lectures are very helpful.
Glad to hear that

yes but query coverage and percentage identity as well

Dear sir, I hope u will be fine.
Sir which test is further proceed for novel genus of organism. Plz explain
use of query and subject ?
how to select range or how it varies?
assalam o alikum- sir mujhy ye samjh nhi aya k" stain novel" hony sy kya murad h?
means every day new strain are discovered in word means new bacteria so NCBI is first method to confirm this novelty on the basis of similarity ok

And your lecture is very informative,Thanks!!
its impossible have 100% value means you are using same sequence in query
@@Prof.Dr.MuhammadNaveed ok sir thanks!
how to know the difference using two different scoring schemes while using blast
It depend upon %age identity based and which give better result use it
How we trimm sequence
I want to ask one question that how we know that the query sequence is novel?
if percentage identity and query coverage are less than 85% then do sequencing again for novelty
Thank you sir
Please guide that how to do sequencing again
If percentage identity is 84% and Query Cover is 94% then it is novel or not?

Your sequences are not good or have addition of other sequence or sequencing error
