Defensive or drug resistant viruses grow by mutation. Viruses are exposed to many cellular factors during the replication of viruses, some of the factors can do actually mutate the viral genomes. Viruses take advantage of these factors to form as a genetically modified (new) virus that may not be cured by a particular drug since the virus has evolved to escape from the effect caused by the drug!
What else can I help you with?
Why would viruses not grow on milk?
Viruses require living cells to replicate and grow. Milk does not contain living cells, so viruses cannot infect or reproduce in milk. Additionally, milk has natural defense mechanisms, such as enzymes and antibodies, that can inhibit the growth of viruses.
What is the chemical that interferes with how viruses grow?
Interferon
What is a biodefence?
A biodefence is any defensive measure taken against an attack using bacteria, viruses or toxins.
Can parasites and virus grow in food?
no. . . Because parasites and viruses can only grow on living matters... There may be saprophytes and bacteria growing in your food. . . Even parasites and viruses can be there but can not grow. .
What non living things grow?
viruses are non-living yet they can grow and spread through bodies
Defensive proteins are manufactured by what system?
Defensive proteins are manufactured by the immune system. These proteins help protect the body from pathogens such as bacteria and viruses. Examples include antibodies and cytokines.
Do viruses grow or develop in a host organism?
Viruses do not grow or develop in a host organism like bacteria do. Instead, they replicate by hijacking the host cell's machinery to make more virus particles.
How do viruses grow and develop over time?
Viruses grow and develop by infecting host cells and using their machinery to replicate. They can mutate and evolve over time, leading to new strains and variations.
What is need for viruses to grow?
They need a living cell. It is essential for replication.
Relationship between sanitation and disease?
A lack of sanitation is a breeding ground for bacteria and viruses to grow. These bacteria and viruses then affect the individuals visiting/living in these environments, and as a result, they are infected. [diseased]
What substance do you use to viruses grow in a laboratory?
the world may never know
Do all viruses grow using sunlight and carbon dioxide?
Viruses do not "grow", much less use sunlight and carbon dioxide to develop. That is what plants do. Viruses enter a host cell, intergrate their DNA with its, and the host cell "builds" more parts of the virus, which assemble in masses, explode out of the cell, and go on to infect new host cells.
