Question

A change in DNA resulting in an incorrect protein is the problem in sickle cell disease. Is this normally the problem in genetic diseases?

A. Yes, the DNA may be "correct" but can produce abnormal proteins which cause disease.
B. No. In other genetic diseases, the proteins are all correctly made, but then they damage the DNA.
C. No. Most genetic diseases result from errors in cell division.
D. Yes, abnormal proteins created by abnormal DNA is the problem in all genetic diseases.
E. It's not clear what the problem is in most genetic diseases.

Answer 1

D. Yes, abnormal proteins created by abnormal DNA is the problem in all genetic diseases.

Step-by-step explanation:

DNA carries the information for the correct development and function of the human body. A gene is defined as a DNA fragment that codifies for a protein, this means that genes carry the information to shape a protein in the ribosomes. If the information is "corrupted" proteins can still be formed but can't work correctly.
