How to identify the mutations by BLASTx
Mutation testing is used to design new software tests and evaluate the quality of existing software tests. Mutation testing involves modifying a program in small ways. Each mutated version is called a mutant and tests detect and reject mutants by causing the behavior of the original version to differ from the mutant.

I wish I understood more of what you are saying. As it is, I only caught an English word here or there. Nevertheless, your video helped me a lot. Thank you so much! Indeed, I found it more helpful than the NCBI’s tutorials (which are great). I like how you got straight to the point and demonstrated the best way to get the comparison done. I feel more comfortable using Blast now. I am wondering whether there is way to take the analysis one step further. Let’s say you blast a sequence and find a similar sequence in the database. Then you select “Pairwise with dots for identities” and find a variant in red, like in your video. Is there a way to easily connect that variant directly to dbSNP or the ClinVar database? Anyway, thank you for making this video. It is superb.

welcome and yes, if this mutation is reported then you may retrieve it from dbSNP or from UCSF genome Browser

Sir,humne blast x hi q use kia hai yaha pr? Hum direct protein ki fasta seq ko lekar b blast kr sktey hai?
@Prof.Dr.MuhammadNaveed
@Prof.Dr.MuhammadNaveed 4 года назад
because BLASTX is translated blast take sequence from nucleotide and convert it to amino acid so we may check mutation at both level as well as know about codon degeneracy

@Prof.Dr.MuhammadNaveed
@Prof.Dr.MuhammadNaveed 4 года назад
Because at nucleotide level confirmation level not up to mark due to the codon degeneracy but at amino acid level no issue of that

Hy sir I just saw your video related to bioinformatics I got assignment related to it I need a help because my teacher say I have to introduce a mutation but I don’t know how to do it if the match is 100% in blast software I can’t do it please help me related to that point
@Prof.Dr.MuhammadNaveed
@Prof.Dr.MuhammadNaveed 2 года назад
you picked sequence form NCBI so might be it matched 100% with first alignment but for rest not which will be the candidates of your mutation

yes you can but not a good way so you just blast protein and then take account mismatches as mutation candidates

Sir ji mujhe ek chez samajh m nhi aa raha h ,ki hum Blastx m nucleotide se Protein m translate karte ..hai and Jo new page m results aata h usme hum ko alignments ko select karke mutation identification karna hai ..but instead of blastx ...if mere pass protein sequence h already then can I choose pBlast or Blastp ~? Qki usme vi ta same result aayega na ...then aur ek doubt ye hai ki ...hum mutation analysis kis sequence ko karte hai ? Jis sequence ko as a reference lete hai ? Or Jo alga alga organism's m us protein sequence ka homology milta hai ? Please reply me .. Thank You

@Prof.Dr.MuhammadNaveed
@Prof.Dr.MuhammadNaveed 4 года назад
because BlastX give results on the base of translated query means we give nucleotide and give results in form of amino acids which is most accurate way of finding mutations at both level. we find mutation in our query sequence on the base of homologues sequences

Nice lecture.Sir i have a query suppose i want to check mutational frequency of a protein ,such as SARS-2 spike protein.Mutational frequency means suppose i took 100 Spike protein sequence and convert them into gene,Now i want to check the mutation point among this 100 gene of that spike protein(that means how much positions become mutated).Moreover i want to see which positons become more mutated among this 100 gene.That means i want to know the frequency of particular positons.Kindly help on this
