how is a genetic diesease different from those caused by bacteria, virus, or other organisms?

Answer 1

A genetic disease is caused by a mutation or mutations passed on to an individual from his or her parents, whereas infection by an external agent causes infectious disease.
Disease caused by an infectious agent is contagious whereas a disease with a genetic cause is not. Treatment for infectious diseases is to try to kill or suppress the agent present in the body. Treatment for a disease with a genetic cause is to currently to try to lessen the effects without correcting the root cause of the disease (mutation). Future cures are hoping to correct the causitive mutation using gene therapy to supply a normal gene.

Answer 2

Genetic diseases can be one of two things:
1. There is a problem with the person's chromosomes, which causes one or more symptoms that make someone ill or make the person different from others (in a way that negatively impacts health). Example: Down Syndrome. This differs from some other genetic diseases because the "bad" genes are caused by a random mutation, and not a direct result of the parents carrying the bad genes.

2. The disease is caused by genes inherited from a person's parents; in other words, the disease is hereditary. Example: diabetes in several members of the same family.

Diseases caused by microbes (bacteria, viruses, fungi, and prions, parasites including worms, protazoa, etc.) are different because they are infectious. They have nothing to do with the person's genes, and will attack anybody who is not immune to them. Example: flu, HIV, sinus infections.

Answer 3

Genetic diseases are caused by mutation in the DNA code which in turn affects the protiens (gene products ) that are made. If the gene products are altered enough they can no longer perform their intended function.

A common example is Sickle cell anemia the Normal hemoglobin binds to oxygen properly. In sickle cell anemia there is a mutation (Only one nucleotide difference) that changes the gene product and it can no longer bind to oxygen as well causing the disease.

Because the heterozygote has some properties of both normal and sickle it offers protection against malaria.

Answer 4

Genetic diseases are caused by defects in the organism's DNA and usually present at birth; they are also usually inheritable. So far, we do not have a way to cure genetic disease.

Infectious disease is caused by an outside agent; it is usually acquired after birth and not heritable. Many infectious diseases are curable.

Answer 5

its is passed through genes. not bateria or outside organisms
