Does the genetic sequence of SARS-CoV-2 end with 33 A's?
This is a poly(A) tail, which is a feature found in the majority of eukaryotic RNAs (especially mRNA) and is also not uncommon in RNA viruses (which essentially mimic endogenous mRNA for their own replication). As with mRNA, this poly(A) tail in coronaviruses is bound by poly(A) binding protein in the cytoplasm [1], which is involved in translation initiation. In coronaviruses, this poly(A) tail is also necessary for replication independent of its role in translation [2].
