Yes, it looks like that, but it isn't. All those distinct lineages are functionally equivalent. That's the point. A detectable difference isn't the same as a functional difference in transmissibility, virulence, etc.
- SomeoneFromCA 6y agoWell you cannot claim either way. There is still circumstantial evidence for a significant difference in virulence and mortality across the globe, so there might be indeed multiple strains, we just do know about it.
- Symmetry 6y agoYou can definitely claim it if, say, a CUA codon is replaced by a CUG codon because both of those code for Leucine and the resulting proteins will be absolutely identical.
- SomeoneFromCA 6y agoThat is not what I said. If there is observable difference between two populations, then indeed there might be two different strains at work. If you want to be super pedantic, not all RNAs are mRNAs, and there might be difference between CUA and CUG in tRNA's behavior.
- jansan 6y agoHow is it known that they are "functionally equivalent"? Is that common knowledge among virologists, has it been tested or simulated?
