Viruses are mainly classified by phenotypic characteristics, such as morphology, nucleic acid type, mode of replication, host organisms, and the type of disease they cause. Scribd will begin operating the SlideShare business on December 1, 2020 In 2019, the ICTV published a proposal to adopt a more formalized system of binomial nomenclature for virus species names, to be voted on in 2020. 14:25, 30 April 2018: 1,750 × 1,120 (140 KB) Michka B (talk | contribs) Création de liens vers Wikipédia.fr (s'ouvrant dans un nouvel onglet) pour : - les noms des éléments chimiques - les familles - les origines - les termes de la légende Affichage du n° d'élément vers la droite. Defective interfering particles are defective viruses that have lost their ability to replicate except in the presence of a helper virus, which is normally the parental virus. CHAPTER 2: CLASSIFICATION OF VIRUSES Prepared by Miss Putri Shareen Rosman Room No:01/24MIC208 - VIROLOGY 1. Satellite-like nucleic acids resemble satellite nucleic acids, in that they replicate with the aid of helper viruses. Clipping is a handy way to collect important slides you want to go back to later.
