What else can I help you with?
What virus infect bacteria?
Bacteriophages are viruses that infect and replicate within bacteria. These viruses inject their genetic material into a bacterium, which then uses the bacterium's machinery to produce more phages. This eventually leads to the lysis of the bacterium and release of new phages to infect other bacteria.
Which ones the smallest a bacterium or a virus?
Bacteria cells. They are the smallest living thing on Earth (known to man).
What is the tail of a bacteriophage specialized for?
The tail of a bacteriophage is specialized for attaching to the host bacterial cell and injecting its genetic material into the cell. It helps the bacteriophage in recognizing and binding to specific receptors on the bacterial cell surface.
How long do viruses to reproduce?
The time it takes for a virus to reproduce varies depending on the type of virus and conditions present. Some viruses, like the flu, can reproduce and spread quickly within a host, causing rapid onset of symptoms. Other viruses may have a slower replication rate.
What type of micro-organism causes tonsillitis?
Tonsillitis is commonly caused by viruses, such as the rhinovirus or adenovirus, but can also be caused by the bacterium Streptococcus pyogenes (Group A Streptococcus).
What diseases are not caused by bacterium?
viruses, genetic conditions etc
What is the smallest ribosome mitochondrion virus bacterium or protein?
Ribosomes are the smallest between mitochondria, viruses, bacterium, and protein. Ribosomes are the building blocks of mitochondria, viruses, bacterium, and proteins.
Do bacteria and virous have a nucleus?
Both bacteria and viruses are prokaryotic, which means they do not contain a nucleus. Both viruses and bacterium are not cells.
What are the similarities between viruses and ribosomes?
Ribosomes are made up of cellular skeletal components viruses are essentially prokaryotic bacterium which had mutated during evolution
What are the four types of pathogens?
The four type of pathogens are bacterium, protists, viruses, and fungi. Parasitic worms are NOT pathogens.
What virus infect bacteria?
Bacteriophages are viruses that infect and replicate within bacteria. These viruses inject their genetic material into a bacterium, which then uses the bacterium's machinery to produce more phages. This eventually leads to the lysis of the bacterium and release of new phages to infect other bacteria.
What are microscopic free floating animals?
Bacterium, perhaps dust mites, and, arguably, viruses.
What are three shapes of viruses?
For computer viruses, they have no physical shape, they are a string or program of codes that are made to effect files Regular viruses have a shape, but they are not needed as they dont effect what they do. Viruses just look like any bacterium, or in a spiderlike form.
Is measles an example of a disease caused by a bacterium?
Measles and mumps are caused by viruses, not bacteria.
What organism produces disease?
bacterium Not all bacteria produce disease, viruses do too. It would be called a pathogen.
Four uncontrollable risk factors for disease?
gender, age, race, environment
Why can't antibiotics be used against viruses?
Because viruses are not bacteria. Antibiotics only work on bacteria. (Viruses are not actually alive . . . they enter a bacterium and take control of its function.)
