Document Summary

Some viruses envelop themselves in host membrane as a form of camo. Tegument is a package of proteins and enzymes a virus may use for quicker infection time and less lag. Genomes are too large and cannot be packed into an icosahedral. Some of the material is packed outside and these viruses are fairly flexible (such as ebola) Land and eject genetic material into bacteria. No symmetrical capsid and it stabilized by covalent connection of two strands (in a circle) No capsid, dna is enclosed by a core envelope surrounded by a membrane that comes from the host. Contain a large number of accessory proteins (enzymes and regulatory proteins). Efficiently packed into an mrna like structure. Use different starts to produce different proteins. Long terminal repeats (ltr) signatures of viruses that represent scars on the host genome. Viruses are made of at least a capsid and nucleic acid. Make up 8% of the human genome (recognized by ltr)
