 In the practical section of this day, we will be using marker gene methods and building a gene sharing network to classify the viruses identified in our metaviromes. Examples of widely used marker genes are for phages include the terminase large subunit (terL), major capsid protein (mcp) and DNA polymerase B (DnaB).

-> 3. How many taxonomic ranks are available to classify the virosphere?
-> 4. What is a realm?
-> 5. How many viral genera are there?
-> 6. Pick one marker gene and describe how it functions in the virus-host interaction, which taxonomic rank it can/cannot identify.
