Document Summary

Copy needs to already be made because it cannot be translated. Not for type 4, because mrna is the same. Type 3: dsrna, need to carry a copy of protein. Arrow: dna ligase (join strands) and dddp (missing nucleotides) Gapped: provides binding site for polymerase enzyme. gapped dsdna (intact) dsdna +ssrna -ssdna gapped dna. Budding: pushes up and out into a circle to leave. Exocytosis: vesicle from golgi and is released at membrane. Usually at least part of replication occurs in nucleus. Not everything done at once, classified as e, m, l genes. Puts cap on each viral mrna so it is. E: taking over the host, necessary for replication, transcription, one is a viral sigma factor. Viral anti-sigma factor is also created so viral rna polymerase is not bonded to. Attacks host dna while viral dna is not harmed/broken down. L: structural proteins, tail capsid, tail fibers and pins, needed for assembly.
