Bioinformatics Counting Point Mutations in DNA with Python [Rosalind Problem]

[@lisamarschhauser8957]

Hey Lana, I just used your code for counting the point mutations - resulted always in 1 independently on the amount of point mutations. But I found a way to fix it :) - Maybe also interesting for others trying to solve the problem :) def hamming_distances(s,t): if len(s) != len(t): print("Strings are not equal size!") else: hamming_dist = 0 for position in range(0, len(s)): if s[position] == t[position]: continue else: hamming_dist = hamming_dist + 1 return hamming_dist print(f"Hamming distance for this example is: {hamming_distances(s, t)}")

Thank you Lisa for checking. I pinned your comment just in case anyone else get’s the same problem. Thank you so much for sharing!:)

[@AliRaza-lo5tg]

actually, you are not using the same function. recheck please

Hey Lana, Your channel is awesome. Thanks for sharing such mind catching videos. I've learned Biopython using your tutorials.

[@LanaDominkovic]

Glad you like them!

Nice video, hope you will resolve others Rosalind problems ( I'm stuck with some of them 😄 )

[@LanaDominkovic]

Let me know which one you are stick with so maybe I can help! Thanks for nice feedback. I am happy that you liked it! ❤️❤️

Which code editor for python do you use? Great video BTW, I loved it.

[@LanaDominkovic]

Hi, I use PyCharm. Thank you for your comment :D I am really glad you loved it

[@jessehines4044]

@LanaDominkovic Of course, you're welcome your videos are great. Wow pycharm, that's expensive because for the scientific version, they charge 99$/month.

[@LanaDominkovic]

@@jessehines4044 you dont need professional, download community edition should be enough :) and that one is free

[@sanaomar2182]

to understand what you are saying I need to understand the symbols TTT and so on, and other stuffs. considering this, what so you recommend me to study first? thanks

[@LanaDominkovic]

Genetic code and nucleotides :)

Hi Lana, really appriciate your efforts. You really explains it very well. I am a bigginer in this feild. I was curious, if we can count number of mutations in each individual sequence of a fasta file (fasta file having multiple sequences) and print out the result " sequence header and corresponding number of mutation detected". In one of my project i have to sort and remove sequences from my fatsa file having mutations more than a set threshold.

[@LanaDominkovic]

Hi, thank you for the nice comment. yes it would be possible to count number of mutation in each individual sequence, you would just need to know delimiter in file which recognises the start of new sequence and when reading file, count sequence by sequence
