Do viruses have DNA?
The properties and behaviour of viruses differ according to their nucleic acid
content. Unlike cells (e.g. bacteria, plant and animal cells), viruses contain either
DNA or RNA, never both; the viral nucleic acid is either single or double stranded.
Is virus a cell?
Viruses are not made out of cells. A single virus particle is known as a
virion, and is made up of a set of genes bundled within a protective protein shell
called a capsid.
What is the lowest life form?
A nanobe is a tiny filamental structure first found in some rocks and
sediments. Some scientists hypothesize that nanobes are the smallest form of life,
1/10 the size of the smallest known bacteria.
What are the disadvantages of microbiology?
The disadvantages are the high costs of microbiological examinations,
and the need for long training times for microbial laboratory technicians
because of the highly technical nature of their duties.
What is the infection?
The invasion and growth of germs in the body. The germs may be
bacteria, viruses, yeast, fungi, or other microorganisms. Infections can begin
anywhere in the body and may spread all through it. An infection can cause fever
and other health problems, depending on where it occurs in the body.
What is the difference between virus and bacteria?
On a biological level, the main difference is that bacteria are free-living cells
that can live inside or outside a body, while viruses are a non-living collection
of molecules that need a host to survive.
Is bacteria living or non-living?
Viruses are not living organisms, bacteria are.
Their “life” therefore requires the hijacking of the biochemical activities of a living cell.
Bacteria, on the other hand, are living organisms that consist of single cell that can
generate energy, make its own food, move, and reproduce (typically by binary
fission)
What's the size of a virus?
To date, research has shown that the viruses that have been identified and isolated
can range in diameter size from 20 nm to as large as 500 nm.
