Unit 5: Classification and Kingdoms

In what kingdom do we classify a virus? None! Viruses are not considered living, so we do not classify them with living organisms.

Structure of Viruses All viruses are composed of: – Nucleic acids: Virus’s genetic material DNA or RNA Code solely for reproduction – Capsid: Protein coat.

Latin for “toxic” or “poison” A virus is a non-living microscopic particle, much smaller than a bacteria, which cannot grow or reproduce apart from.

Viruses A submicroscopic pathogen From the Latin: Poison: A slimy liquid.

Viruses Living or Not Virus Virus – small particle made of 1.Nucleic acids either DNA or RNA 2.Surrounded by a protein coat.

CHAPTER 19 NOTES VIRUSES CHARACTERISTICS OF VIRUSES Prokaryotic or Eukaryotic: Neither (no organelles or membranes) Unicellular or Multicellular: Neither.

Viruses Living or Not Virus Virus – small particle made of 1.Nucleic acids either DNA or RNA 2.Surrounded by a protein coat.

The Virus. What is a Virus? Virus Latin for Poison Non-cellular particle with DNA or RNA 1 or 2 Protein Coats (Capsids) May have Viral Envelope - Phospholipids.

Viruses. Biology of Viruses Structure of Viruses: Size -Less then 0.2 microns Parts of the Virus 1)Capsid: -Made of protein subunits 2) Inner core: made.

1. Non-living 2. Not cellular 3. Unable to reproduce except in a host cell 4. Smaller than bacterial cells 5. CANNOT BE TREATED WITH ANTIBIOTICS; only.

Virus. biological particle/ pathogen virus comes from Latin “poison” living? or non-living? rabies virus Virus.

 Viruses are small infectious agents  They are so small that they can only be seen with a very powerful electron microscope Ebola Virus under electron.

VIRUSES. What is a Virus? Made up of DNA or RNA surrounded by a protein coat Made up of DNA or RNA surrounded by a protein coat Cause disease and infection.

Viruses Virus: A noncellular particle composed of genetic material that can invade living cells. –Viruses are considered by most to be nonliving since.

Viral Cycles: Lytic Lysogenic

Chapter What is a virus? A virus is nucleic acid wrapped in a protein coat Can be DNA or RNA Viruses are considering nonliving because they can’t.

Viruses. 1.What is a virus? 2. nonliving 2. they have an outer layer called a capsid 2. they contain DNA or RNA 3. never both.

This is the image of a bacterium being attacked by viral particles. You can see the contrast in size easily. In ancient Rome, ‘virus’ meant “poison” or.

Chapter 19.  Non-living ◦ Non-cellular ◦ Cannot grow or reproduce on its own ◦ No metabolism  Cause disease ◦ AIDS, colds, flu, measles, mono  Cause.

Use the picture and this information to help you make your decision: 1.Viruses contain RNA or DNA 2.Viruses cannot replicate on their own, they must use.

Chapter 18.1: Viruses. 1. Viruses are composed of nucleic acids enclosed in a protein coat and are smaller than the smallest bacterium.

Viruses. Virus: Segments of nucleic acid (DNA OR RNA) within a protein coat (noncellular); NONLIVING; much smaller then prokaryotes Must reproduce within.

Viruses 1.Identify the structures of viruses 2.Explain the differences between the lytic and lysogenic cycles of viral reproduction 3.Recognize the medical.

VIRUSES. SIZE of VIRUSES  Viruses are so small they must be measured in “nanometers”  1,000 nanometers = 1 micrometer  1,000 micrometers = 1 millimeter.

Viruses. Tiny 1/2 to 1/100 the size of smallest bacterium Nonliving Do not fulfill the criteria for life Do not carry out respiration, grow or move Can.

Quick Facts Viruses are not living things Viruses don’t have their own kingdom Viruses kill their host cells There are over 800 viruses known to man Virus’ are named by the disease they cause Many famous viruses are HIV, Influenza, and E. coli T4 Virus

Replication The Virus needs a host cell to replicate and exist There are two different cycles, the Lytic Cell and Lysogenic Cell The five steps are absorption, entry, replication, assembly, and release Steps of Replication

Structure Has an inner core of nucleic acid containing an DNA or RNA (their genetic material) Has an outer coat of protein called a capsid Some viruses have an additional layer surrounding the capsids called an envelope The arrangement of the proteins in the capsids determines the virus’ shape

Feeding and Obtaining Energy Viruses do not feed Viruses do not convert energy Viruses operate by reacting to elements T Bacteriophage virus Norwalk-like Virus
