Answer:
During Bluetongue virus (BTV) replication, the viral core assembly occurs in the cytoplasm of the infected host cell. The viral core is assembled from multiple copies of the VP3 protein, which self-assembles into an icosahedral lattice that encloses the single-stranded RNA genome of the virus. The assembly process requires the interaction of VP3 with other viral proteins and with host cell factors. Once the core is assembled, it is surrounded by a layer of the VP2 protein to form the mature virion, which is then released from the infected cell.
