Which statement regarding lysosomal storage diseases is true?

a). a gene defect makes lysosomes unable to store degraded compounds.
b). accumulation of stored iron results in cell, tissue, and organ dysfunction.
c). defective enzymes result in the accumulation of potentially toxic substances.
d). mutations in the genes coding for different types of collagen produce substances that are toxic to brain cells.

The correct answer is option c). "Defective enzymes result in the accumulation of potentially toxic substances".

Explanation:

Lysosomal storage diseases (LSDs) are a group of rare metabolic disorders that have a genetic influence and are, most of time, autosomal recessively inherited. The molecular basis of the diseases are an accumulation of potentially toxic substances due to the presence of defective enzymes. In fact, LSDs are often triggered by a single defective enzyme that is required for lipids metabolism.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
