Biology According to the creatures that infest, we consider four groups of viruses: Bacteriophages: parasitize bacteria; mycophagous: parasitize fungi; animal viruses: parasitize animals; plant viruses: parasitize plants. It is important to remember that the fact that a virus belonging to a certain group does not mean that it can parasitize any individual in that group. For example, a virus parasite or a given animal can not parasitize animals of other species. SEARCH So here we go ... Do a search on sheets DNA: the long chain of life, this book and answer the following questions: What is a nucleic acid? Where are they found? Where are these acids in living prokaryotes? And in living eukaryotes? And the viruses, which are nucleic acids? But now we must try to locate the virus in the history of the evolution of life on Earth. One explanation for the science is that they originated from fragments of nucleic acids released by the oceans in primitive cells, which are surrounded by proteins and acquired the ability of replicating itself within a cell and are transmitted to others. You may have noticed we have not talked virus male and female. And then, how do they reproduce? To reproduce the virus must invade cells and "hijack" the cellular mechanism of its host. The reason viruses are also called "obligate intracellular parasites." To invade the host cell it interferes with the reproductive mechanism to "force" it to produce new viruses. This process is called replication, because viruses are identical copies of itself. For you to understand the process of reproduction, we will use the bacteriophage virus 'or phage' (Figure 3), which is one of the most studied viruses as attacks bacteria reproducing inside. These viruses are harmless to humans and other animals. Virus: "poisonous fluid"

Biologija Prema stvorenja koja nasrtati, smatramo četiri skupine virusa: Bakteriofagima: živjeti kao parazit bakterije; mycophagous: živjeti kao parazit gljive; životinjski virusi: živjeti kao parazit životinje; biljni virusi: živjeti kao parazit biljaka. Važno je zapamtiti da je činjenica da je virus pripadnosti određenoj skupini ne znači da se može živjeti kao parazit svaki pojedinac u toj skupini. Na primjer, virus parazit ili dati životinje ne mogu živjeti kao parazit životinje drugih vrsta. TRAŽI Dakle, ovdje mi ići ... Da li pretraživanje na listove DNK: dugom lancu života, ova knjiga i odgovoriti na sljedeća pitanja: Ono što je nukleinska kiselina? Gdje se nalaze? Gdje su ti kiselina u životnim prokaryotes? A u dnevnom eukariota? I virusi, koji su nukleinske kiseline? Ali sada moramo pokušati pronaći virus u povijesti evolucije života na Zemlji. Jedno od objašnjenja za znanost je da potječu od fragmenata nukleinskih kiselina koje je objavio oceana u primitivnih stanica, koje su okružene proteina i stekla sposobnost se replicira unutar stanice, a prenose drugima. Možda ste primijetili nismo razgovarali virus muško i žensko. A onda, kako se razmnožavaju? Za reproducirati virus mora upasti stanice i "oteti" stanični mehanizam svog domaćina. Razlog virusi također nazivaju "obvezuje unutarstanični paraziti." Za upasti u stanice domaćina ometa reproduktivnog mehanizma za "prisiliti" je za proizvodnju novih virusa. Ovaj proces se naziva replikaciju, jer virusi su identične kopije sebe. Za vas razumjeti proces razmnožavanja, koristit ćemo bakteriofag virus 'ili fag' (Slika 3), koji je jedan od najvažnijih studirao virusa su napadi bakterija reproduciranje unutra. Ovi virusi su bezopasni za ljude i druge životinje. Virus: "otrovne tekućine"
