Title: Why does the SARS-Cov2 genome has letter t
ThreadText: # Why does the SARS-Cov2 genome has letter t
  
  (Asked by: username_0 on 2021-09-20)
  
  `ATTAAAGGTT TATACCTTCC CAGGTAACAA ACCAACCAAC TTTCGAT...` is part of the 5'UTR of genome of an RNA virus SARS-Cov-2.
  
  RNA contains letters `C`+`G`+`A`+`U`.  
  DNA contains letters `C`+`G`+`A`+`T`.
  
  Why are there letters `T`, in the SARS-Cov-2 genome, instead of `U`?

  We sequence and therefore typically report assemblies as DNA sequences, even if they're actually RNA.
