What were rickettsiae and chlamydia once thought to be?
Rickettsiae and Chlamydia were once thought to be viruses due to their small size and intracellular lifestyle, but they are actually classified as bacteria. They are both obligate intracellular pathogens that require host cells to multiply.
Viruses reproduce by what process?
Viruses reproduce by taking over a host cell's machinery to make copies of themselves. They cannot reproduce on their own and rely on infecting cells to replicate.
Are viruses a eukaryote?
No, viruses are nonliving.
Viruses that consist of only a nucleocapsid are considered what?
Viruses that consist of only a nucleocapsid are considered naked viruses. These viruses lack an outer lipid envelope and rely on the nucleocapsid structure for protection and infectivity. Naked viruses tend to be more stable in the environment compared to enveloped viruses.
Viruses that evolve in a geographically isolated area and are pathogenic to humans are called?
Emerging viruses
Why growing or cultivation of viruses is of medical importance?
-to isolate and identify viruses in clinical specimens -prepare viruses for vaccines -to research in detail the viral structures, multiplication cycles, genetics, and effects on the host cells

Why are viruses thought to be one of the greatest threats to human dominance of the planet?
Viruses are considered to be a serious threat to humans because they are very difficult to control. Very few things can control viruses except antivirals.
Does a virus actually get into the DNA of a cell?
Viruses combine their genetic material with that of the host cell they have invaded. See the related question below about how viruses reproduce for more information and many related questions.
What viruses reproduce by?
The Lytic Cycle or by Budding without lysis. See the related questions below for more information.
How do the cilia inside the nose prepare the air for going into the lungs?
Cilia inside the nose filter the air for most dust, allergens, viruses, and bacteria.
How did viruses come to be?
Viruses are thought to have evolved from ancient cellular organisms, possibly derived from genetic elements that "escaped" from cells. It is believed that viruses originated billions of years ago and have co-evolved with their hosts, adapting to exploit different cellular mechanisms for replication and survival.
What type of virus is influenza?

Can you get a cold if you step on the cold ground?
No, colds are caused by viruses and being cold does not cause or worsen a cold. See the related questions.
Can a DVD writer have a virus?
DVD writes are hardware devices and are not prone to viruses. The software that is used by computers to prepare and send data to the DVD writer can be infected by a virus.
