Question

the phenomenon in which microbial antigens have determinants similar to normal human cells and cause a cross - reaction with self antigens is called

Explanation:

This question is about a biological/medical concept. The phenomenon where microbial antigens have determinants similar to normal human cells, leading to cross - reaction with self - antigens, is known as molecular mimicry. In the context of Natural Science, specifically in the subfield of Medicine and Health (or Biology), this concept is relevant as it pertains to the immune system's response and how pathogens can mimic self - antigens, potentially leading to autoimmune - like responses or other immune - related issues.

Answer:

molecular mimicry
