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?

It is very essential then to look the genetic makeup to normal cells and compare them to see as it could help in choosing personalized therapy for Lee.

Cancer cell's genes are very unstable in nature and they replicate very fast speed. The use of non cancerous cells will better tell if the cancer is genetic or not when compared to the use of biopsy tissue.

Germline testing is often carried out to know if an individual has a gene mutation that can increase the risk of developing cancers.

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.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
