Question
levels of biological organization exhibited by bacteriophage capello Project Learning 1 Between the Living and the Dead The question of whether a virus is alive or dead has been subject of scientific debate for centuries. In this assignment, you will join the debate and offer your selection of whether viruses are alive, dead or somewhere in between using the properties of life as your guideline. For this as assignment, you will prepare a Microsoft PowerPoint for an investigation of the virus called a bacteriophage SLIDE 1. Title Slide (Full Name, Class, Date) SLIDE 2. rganization Slide. A description of bacteriophage structure. Identify all levels of biological organization exhibited by bacteriophage including an examplef each level. (e.g. atom - oxygen)Explanation / Answer
Structure of bactetiophase: The nucleic acid may be either DNA or RNA and may be double stranded or single stranded.
Three basic structural forms of phage : An icosahedral head (20 sides) with a tail,an icosahedral head without a tail.and a filamentous form.
Bacteriophage also called phage or bacterial virus any of group of viruses that infect bacteria. Bacteriophage were discovered independently by Frederick w.twort and Felix d herelle. Herelle coined the term bacteriophage.
Bacteriophages are single celled prokaryotic organisms.
Characteristic's of bacteriophage: phages classifieds in a number of virus family's some example of inoviridae,microbicide, rudiviridae, and tectiviridae. Like all viruses phages are similar organisms that consist of a core of genetic meterial nucleic acid surrounding by protein capsid.
Life cycles of bacteriophage: During infection phage attaches to bacterium and inserts it's genetic meterial into the cell.after that a phage usually follows one of two life cycles lytic (virulent) or lysogenic (temperate).Lytic phages take over machinery of cell to make phage components. They then destroy or lyse the cell releasing new incorporate their nucleic acid into the chromosomes of the host cell and replicate with it as a unit without distroying the cell.under certain conditions lysogenic phages can be induced to follow a lytic cycle.
