Name 4 parts of Bacteria Phage virus from top to bottom
Capsid, Nucleic Acid (in capsid), Tail, Tail fibers
What is the capsid made from in virus
Protein
What is in the capsid of virus
Nucleic Acid (DNA or RNA)
What part of virus attaches to the host to allow injection
Tail fibers or spikes
what two things are viruses made up of
capsid (protein coating) and Nucleic Acid
What do virus’s need to reproduce
a host cell
what do we use to see virus’s
electron microscope
what is a virus that invades a bacteria
bacteriophage
are virus’s made up of cells
no
can virus’s reproduce
yes; only with host
can virus’s grow and develope
no
can virus’s obtain and use energy
no
Do virus’s respond to the environment
no
Do virus’s have universal genetic code
yes
can virus’s maintain homeostasis
no
do virus’s evolve
yes
are virus’s living
no
what are two main cycles of viral infections
Lytic and Lysogenic
List Lytic cycle in order
Attach to host cells, Bind to receptors, Injects nucleic material, Virus directs host to use its resources to reproduce cell parts, when directed/activated they assemble, lyse and escape the host
List Lysogenic cycle in order
Attach to host cells, Bind to receptors, Injects nucleic material, material binds and hides in host’s genetic material, as cell reproduces virus material is too, when directed/activated they assemble, lyse and escape the many hosts.
Name at least two virus’s that effect humans
Cold, flu, hepatitis, HIV, pneumonia, rabis
Name at least two virus’s that effect plants
Tobacco mosaic virus, Cucumber mosaic virus, Apple mosaic virus
Name at least two virus’s that effect animals
rabis, pneumonia, brain wasting diseases, mad cow disease
