Don"t replicate by splitting, but by making component parts and assembling them into new viruses. Genome type: can be dna or rna. Capsid: protein or glycoproteins that covers and protects genome, types: Regular or shell (hollow structure made of regular geometric shapes)- hollow bunny easter candy [sphere or geometric shape] Nucleacapsid (build capsid around nucleus)- dried orange peel with chocolate drizzled on [cylindrical] Envelope: a membrane surrounding the capsid, usually has integral protein for attaching to host cells, stolen from host cells by exocytosis. Trick host cell into making vesicles so it can leave cell. Parts: head (holds genome, tail (coiled and energetic enough to pierce cell, tail fibers (hold it to host bacteria)
