Unformatted text preview: MULTIPLICATION OF ANIMAL VIRUSES This process follows the same basic pattern as bacteriophage multiplication, but there are several differences. Here is a brief comparison: STAGE BACTERIOPHAGE ANIMAL VIRUSES ATTACHMENT TAIL FIBERS ATTACH TO CELL WALL PROTEINS ATTACHMENT SITES ARE PLASMA MEMBRANE PROTEINS AND GLYCO-PROTEINS PENETRATION VIRAL DNA INJECTED INTO HOST CELL CAPSID ENTERS BY ENDOCYTOSIS OR FUSION UNCOATING NOT REQUIRED ENZYMATIC REMOVAL OF CAPSID PROTEINS BIOSYNTHESIS IN CYTOPLASM IN NUCLEUS (DNA VIRUSES) OR CYTOPLASM (RNA VIRUSES) CHRONIC INFECTION LYSOGENY LATENCY; SLOW VIRAL INFECTIONS; CANCER RELEASE HOST CELL LYSED ENVELOPED VIRUSES BUD OUT; NONENVELOPED VIRUSES RUPTURE PLASMA MEMBRANE The following section discusses the action of animal viruses in more detail. Both RNA and DNA viruses share most of these processes, but the process of biosynthesis differs, as does the process...
