A given combination of 7 bases has a probability of occurring of 1/16,384. Since the COVID genome is about 22k bases long I guess you have pretty good chance of it appearing in there somewhere. This assumes uniformity, which of course is not true. COVID’s genome is under crazy intense selection pressure!
- shellfishgene 6y agoThe sequence GATTCA appears 4 times in the reference version of the COVID genome :) (Go to https://www.ncbi.nlm.nih.gov/nuccore/NC_045512 https://www.ncbi.nlm.nih.gov/nuccore/NC_045512, pick "Find in this Sequence" on the right)
- jonplackett 6y agoAWESOME! I just did a text search for it on github. Maybe it didn't pick any up that had a line break in the middle. I'm much happier now.
- ImaCake 6y agoYep, the usual coding tools aren't ideal for bioinformatics. We have our own set of tools that work well with the various "standard" formats for sequence data.
