Question

In order to test Lee for a genetic disorder, Dr. Aikenhed will probably take a sample of cells containing his genomic DNA by swabbing his cheek or taking a blood sample. Why is it important to use non-cancerous cells to test Lee for a genetic disorder instead of the biopsy tissue?

Answer 1

Answer:

Cancer is a chronic disease in which cells reproduce abnormally, exceeding the capacity of the body tissues to assimilate such reproduction, which causes alterations in these cells and in the organs they affect.

Therefore, if a sample is required to determine some type of genetic disorder in the patient, non-cancerous cells should be used, since these will contain genetic material free of any alteration caused by said disease and, therefore, will be a test of greater accuracy to determine said disorder.
