PPT-Baraminic analysis of Nucleocytoplasmic Large DNA viruses

Creation Research Society Conference Dr Matthew Cserhati Ann Arbor MI July 2830 2016 Introductory thought The disturbing fact that most girus genes might not have originated from one of todays three cellular domains only helps revive the spectrum of intelligent design. Chapters 12 and 13. Viral Characteristics and Structure. Why Viruses aren’t Alive. General Characteristics of Viruses. Name derives from the Latin for “poison”. Obligatory intracellular parasites. DNA Enveloped . Viruses. I. Objectives. In this lecture you will learn about properties, pathogenesis, clinical picture and diagnosis of: . Herpesviruses. . (HHVs 1 to 8). Poxviruses. Smallpox Virus. What is a Virus?. Very small . Non-living particle. Made up of nucleic acid. . and proteins. Can only reproduce by infecting living cells. Do not carry out respiration, grow or develop. Structure. Viruses have an inner core which contains either RNA or DNA. Viruses Are Not Cells!. There are several structural and functional differences between cells and viruses. The structural differences include:. No nucleus. No cell membrane. No organelles. The functional differences include:. What do viruses need to reproduce?. Other viruses. Host organisms. A nutrient medium. An enzyme solution. Which characteristic do viruses possess in common with living cells?. They contain a nucleus and organelles.. Viruses . A nonliving (?) particle made of proteins, nucleic acids, and sometimes lipids (fats). Viruses only reproduce by infecting living cells. Most viruses can only be seen with an electron microscope. EQ: Why are viruses considered to be non-
living?. Characteristics:. *Nonliving particles made of . nucleic acid. and a . protein coat . enlosed in a . capsid. shell... *In order to reproduce, all viruses must have a . -It’s not a plant or an animal.. -It’s not a fungi, protist, or bacteria.. WHAT IS A VIRUS?. A virus is an . infectious. agent made up of . nucleic. acid (. DNA. or . RNA. ) wrapped in a . protein. -It’s not a plant or an animal.. -It’s not a fungi, protist, or bacteria.. WHAT IS A VIRUS?. A virus is an . infectious. agent made up of . nucleic. acid (. DNA. or . RNA. ) wrapped in a . protein. Draw the basic structure of a virus. Label and define capsid, viral envelope and nucleic acid.. Ch. 17 Warm-up. Draw the lytic/lysogenic cycle.. What stage of the lytic-lysogenic cycle is a virus virulent? Temperate?. DNA . is a molecule in your cells’ nuclei that can be . used as instructions by your cells . to make new cells, and pigments for your hair and skin.. What is DNA again?. The DNA instructions are really a pattern of 4 different chemicals read as a code by the cell’s nucleus.. (Assistant Professor). College of Fisheries, . Kishjanganj. BASU, Patna. Characteristics of viruses. Viruses may be regarded as . exceptionally complex aggregations . of . nonliving chemicals . or . exceptionally simple living microbes. Lec. : 4. Non-enveloped DNA Viruses. Non-enveloped . viruses are surrounded by a protein coating, commonly referred to as a capsid. The capsid does the job of attaching to host cells. .. Non-enveloped . ANSWERS CAN BE FOUND IN CHAPTER 19 SECTION 2 on VIRUSES (you need to look at the WHOLE SECTION).. HELPFUL START PAGE= 474. Bacteria & Viruses . What’s the difference??. A little review….
