Document Summary
Advantages: leads to the molecular level and use of molecular tools, every time there is a study conducted there is a lot of genomic discoveries developed. Virions virus particle, consists of an infective nucleic acid contained within a protective shell made of protein. Viroids smaller than viruses, infectious agents, nucleic acid genome is the entire infectious particle, no protective capsid. Usually viruses have small genome containing dna or rna contained in a capsid composed of capsomeres, some viruses have evolved further and have specific genes that make proteins of an envelop. Enveloped viruses consist of a protein capsid and tegument proteins enclosed within phospholipid membrane derived from the host cell, includes virus-specific proteins. Baltimore classification: 7 categories, based on the composition of their dna. Retrovirus specific feature genome contains reverse transcriptase to transcribe. Different order of gene sequence causes diversity within viruses resulting in lysogeny in bacteria.
