gollark: It's 30KB even in a wildly inefficient text format, so with a sensible 2 bit per nucleotide encoding it's 8ish.
gollark: It got sequenced a while ago. The RNA sequence isn't actually very big.
gollark: I copied the SARS-CoV-2 source code into potatOS, actually.
gollark: Oh, are you being quarantined for potatOS?
gollark: Wait, how come I can apparently still ping them if they left?
