Question

Viral genetics mechanism → sharing of proteins but no exchange of genetic material → [?]

Accepted Answer

Complementation → virus lacks a functional protein to replicate so it "borrows" it from another virus (HDV borrows viral coat from HBV) → required for HDV pathogenesis as it lacks a genomic code for envelope protein → HDV utilizes HBV envelope protein (HBsAg) to release its progeny → HBsAg functions in both HDV | HBV

Front	Viral genetics mechanism → sharing of proteins but no exchange of genetic material → [?]
Back	Complementation → virus lacks a functional protein to replicate so it "borrows" it from another virus (*HDV* borrows viral coat from *HBV*) → required for HDV pathogenesis as it lacks a genomic code for envelope protein → HDV utilizes HBV envelope protein (HBsAg) to release its progeny → HBsAg functions in both HDV \| HBV
