NOTES: CH 19 - The Genetics of Viruses. Overview: Microbial Model Systems ● Viruses called bacteriophages can infect and set in motion a genetic takeover.
Viral Structure, Lifecycles and Aids. I. Virus- segment of DNA or RNA wrapped in a protein coat.
CHAPTER 19 VIRUSES 1. OVERVIEW 2 Viruses called bacteriophages can infect and set in motion a genetic takeover of bacteria, such as Escherichia coli.
Viruses I can reproduce inside a living cell, yet I am dormant (inactive) outside a cell Q: Am I living or non- living? Q: Am I a eukaryotic or prokaryotic.
Chapter 19~Viruses. Viral structure Virus: “poison” (Latin); infectious particles consisting of a nucleic acid in a protein coat Viruses are not cells.
VIRUSES Chapter 19. What is a virus? A virus is a submicroscopic infectious particle composed of a protein coat (capsid) and a nucleic acid core (either.
Viruses Gene Regulation results in differential Gene Expression, leading to cell Specialization.
