If you find an example of a sequenced string of coronavirus it is about 30.000 long. Looking for example here https://nextstrain.org/ncov/europe you'll see that by far the largest part of this is actually coding. But is that because that is the entire strain or is it because they are only showing the ORF-part? If the latter is the case how large is the non-coding part then compared to the coding part?

  • $\begingroup$ 30Kb is the total length of the genome, including non-coding regions. $\endgroup$ – Fizz May 3 '20 at 15:39
  • $\begingroup$ And I think the reason why it's not easy to find a % of non-coding region(s) stated for almost any virus is that it's not very certain how much is actually non-coding given all the "tricks" (non-canonical translation) viruses use microbiologyresearch.org/content/journal/jgv/10.1099/… $\endgroup$ – Fizz May 4 '20 at 6:02
