Since you specifically mentioned DNA similarity and not strings in general, I assume you want to align the sequences rather than just the Levenshtein distance between them... If that is the case, I recommend using Biopython (https://biopython.org/) for alignments. There are modules for pairwise sequence alignments both global and local alignments.

Not really or at least I haven't had that problem. It would be a problem if they used both \r and \n at the same time. in that case you can always do \r\n to \n or something like that.

My favorite command when dealing with csv/txt files generated by Microsoft products:

   perl -p -e 's/\r/\n/g' Bad_Microsoft.csv Good_unix.csv

DNA is normally and naturally right-handed which means your logo is wrong!
