Paul Bieniasz joins TWiV to discuss his lab’s discovery that the coronavirus nuclease NSP15 cuts viral RNA into oligonucleotides that are reinserted elsewhere in the viral RNA, generating insertion mutations at a frequency above 10⁻³ per genome, including new furin cleavage sites at the spike S1/S2 junction.
