disease causing, nonliving particles composed of an inner core of nucleic acids surrounded by a capsid
living cell in which a virus replicates.
also called phages, viruses that infect and destroy baceteria.
outer coat of proteins that surrounds a virus's inner core of nucleic acid.
viral replication in which a virus takes over a host cell's genetic material and uses the host cell's structure and energy to replicate until the host cells burst, killing it.
ciral replication cycle in which the virus's nucleic acid is integregated into a host cells chromosome.
viral DNA that is integregated into a host cells chromosome and replicated each time the host cell replicates.
type of viral replication where a virus uses reverse transcriptase to make DNA from viral RNA.
enzyme carried in the capsid of a retrovirus that helps produce viral DNA for viral RNA
a virus like infectious agent composed of only protein with no genetic material.
virus like infectious agent that is composed of only a single, circular strand of DNA.
autotrophic process wehre organisms obtain energy from the breakdown of inorganic compounds containing sulfur and nitrogen.
asexual reproductive process in which one cell divides into tow seperate genetically identical cells.
form of sexual reproduction in some baceteria where on baceteriam transfers all of part of its genetic material to another.
baceteria that require oxygen for cellular respiration.
baceteria that are killed by oxygen and can survive only in oxygen free enviornments.
structural formed by baceteria during inffavorable conditions that caontains DNA and a small amount of cytoplasm encased by a protective outer covering.
poison produced by a baceterium.
metabolic process in which baceteria use enzymes to convert atmospheric nitrogen into ammonia.
