But multipartite viruses may infect and spread in multiple ways. For example, viruses cause AIDS (Acquired immune deficiency syndrome), influenza (flu), chicken pox, and the common cold. 2)They are ultra-microscopic and can only be visualized under electron microscope. The capsid is made of proteins and glycoproteins. Figure %: General virus structure All viruses have a capsid or head region that contains its genetic material. Words. They are non-cellular and very simple in structure, consisting mainly of a nucleic acid surrounded by a protein envelope called capsid. A.Viruses are composed of DNA or RNA molecules surrounded by a protein coat. At the bottom of the Y shape below, write the characteristics that both bacteria and viruses share. Their exact nature was a mystery for long. When viruses infect the cells of their host, they may cause disease. Because of this, the debate of whether viruses are living or non-living continues. That is, they depend on the host cell for the raw materials and energy necessary for nucleic acid synthesis, protein synthesis, processing and transport, and all other biochemical activities that allow the virus to multiply and spread. The Baltimore classification is the most commonly used for studying the system of virus classification. ADVERTISEMENTS: Read this article to learn about the characteristics, importance and control of microorganisms such as bacteria, fungi and viruses. Because most viruses are extremely well adapted to their host organism, virus structure varies greatly. There are 7 characteristics that we need to go through. Give the general characteristics of Viruses 28. Give the significance of fungi.

Viruses infect and live inside the cells of living organisms. Viruses can reproduce only using a host cell. Microbiology (Greek, mikros—small; bios-life) is the science of small or microscopic organisms. D. Lytic viral infection often results in destruction of the host cell. Characteristics of living organisms . Section 1: Studying Viruses and Prokaryotes Study Guide A KEY CONCEPT Infections can be caused in several ways. Compare and contrast the metabolic diversity of bacteria in one of the two groups below. 5. It does not have well-defined body apparatus like other microbes or living beings have. These types of viruses are very infectious that they can perform different actions on an infected computer. That's why viruses are not included in the category of micro-organisms. Different viruses have different viabilities (‘life’ spans, or times during which they can infect a host). 2. *Response times vary by subject and question complexity. 27. d. have a protein coat. They are ultra microscopic and visible only under electron microscope. to. Bacteria are not immune to viral hijackers which are known as bacteriophages—viruses that infect bacteria. Multipartite viruses may infect both the executable program files and the boot sector. 1. characteristics of viruses Essay Examples. 2. 2. Not all animal viruses undergo replication by the lytic cycle. b. can be killed using antibiotics. If even a single one of these characteristics are not present in an organism, then it not alive. a. contain genetic material. [NCERT] Answer: ... Microorganisms exhibiting the characteristics of living and non-living organisms are known as (a) bacteria (b) virus (c) algae (d) fungi Most of the viruses are spread via one method or deliver a single payload. RNA replication is more prone to errors than DNA replication. Characteristics of Viruses: Viruses are microscopic infectious agents that use the host cells' machinery to replicate. 2. How Viruses Interact with Bacteria. The vast majority of these infect … They are non-cellular and very simple in structure, consisting mainly of a nucleic acid surrounded by a protein envelope called capsid. 69. Which statement is true about viruses? When scientists apply this list of criteria to determine if a virus is alive, the answer remains unclear. Introduction to the Viruses. All living things need to reproduce and grow. It seems strange that a human being shares a trait with a flower or a worm, but we do in fact, we are all living on the same planet and require much of the same things to survive. The various characteristics of viruses are: They are smaller and simpler than bacteria. Give the significance of Protoz Q.3 Briefly explain following (6 Marks each) 1.
