can parasites hide on your body by imitating or assuming your DNA?

Answer 1

Parasites wouldn't imitate or assume your DNA. More then likely they would have proteins on their surface that is recognized by your immune system. If your immune system recognizes it as a self-molecule, then the parasite could continue living because the immune system would not fight it. This is the best way to "hide in your body."

Answer 2

If a parasite could become your DNA, it would have all the characteristics of your DNA. Thus, it would not have the ability to turn into a parasite.

Viruses, however, invade your cells and hijack the manufacturing equipment contained inside, causing the cell to produce more viruses, instead of healthy cells. That's the closest thing to "imitating or assuming" that I can think of.

Answer 3

Parasites which are successful tend to do it by avoiding the body's immune system. They cannot change their DNA to be the same as a host. Most likely they are successful because they coat themselves with proteins that are not recognised as foreign by the antigen/antibody system, or they hide within other cell. The malarial parasite, plasmodium, hides within red cells to escape being destroyed by monocytes (phagocytic white cells).
So, it is more likely that they mask or hide themselves.

Answer 4

sure,yeast,fungii have 92% of people dna,,,,,i think a small number of folks have a dna strands or a few ligands of difference vs the norm this increases similarity to human dna ,impairing the selectivity of the immune system, leaving them prone to getting psoriasis,candida albicans,dandruff,nail fungus,histoplasmosis.etc.

Answer 5

Retroviruses do exactly this.
