Document Summary
Can only replicate inside of a host cell. No metabolism: purpose it to make more viruses aka function is replication. Virion enters cell and its dna is uncoated: 3. Part 2: biosynthesis viral dna replicated, some viral proteins are made. Virions released - **may or may not kill host cell** o. What are viruses made of: all viruses have protein coats and one nucleic acid, 1. Nucleic acid ds dna (eg herpes) ss dna (eg b19 fifths disease) ds rna (eg rotavirus) ss rna (eg rhinovirus, flu virus, rabies: some also have an envelope. The entry of viruses into host cells o o. The lytic cycle of a t-even bacteriophage complex virus: injects dna into host cell, then goes through process of replication and release, does not use energy when virus attaches, chemical reactions occur that cause contraction o. This is the lytic cycle lyses cells upon completion of cycle.
