When comparing Tay-Sachs disease and Duchenne's muscular dystrophy which of the following do both have in common?
A.they both involve malfunction of the nervous system
B.they both involve mutations in which fat replaces normal tissue
C.they both are disorders that are equally distributed in the general population
I think it is B not sure
Since this is not my area of expertise, I searched Google under the key words "Tay-Sachs" and "Duchenne" to get these possible sources:
http://en.wikipedia.org/wiki/Tay-Sachs_disease
http://en.wikipedia.org/wiki/Duchenne_muscular_dystrophy
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
Which alternative do these sources support?
I hope this helps. Thanks for asking.
To determine which of the options is correct, we need to compare Tay-Sachs disease and Duchenne's muscular dystrophy.
Tay-Sachs disease is a genetic disorder that primarily affects the nervous system. It is characterized by the accumulation of a fatty substance called GM2 ganglioside in the cells of the brain and spinal cord. This accumulation leads to the progressive destruction of nerve cells, resulting in the deterioration of motor skills and cognitive abilities.
Duchenne's muscular dystrophy, on the other hand, is a genetic disorder that primarily affects the muscles. It is caused by a mutation in the dystrophin gene, which leads to the absence or deficiency of the dystrophin protein. This deficiency results in the progressive degeneration and weakness of the skeletal and cardiac muscles.
Now, let's examine the options:
A. They both involve malfunction of the nervous system: This statement is true for Tay-Sachs disease as it primarily affects the nervous system. However, Duchenne's muscular dystrophy primarily affects the muscles, so this option is not applicable to both diseases.
B. They both involve mutations in which fat replaces normal tissue: This statement is not accurate for either Tay-Sachs disease or Duchenne's muscular dystrophy. In Tay-Sachs disease, fat accumulates in the nerve cells, but it does not replace normal tissue. In Duchenne's muscular dystrophy, there is no involvement of fat replacing normal tissue. Therefore, this option is not correct.
C. They both are disorders that are equally distributed in the general population: This statement is not accurate for either disease. Tay-Sachs disease is more prevalent in individuals of Ashkenazi Jewish descent, while Duchenne's muscular dystrophy affects males predominantly. Therefore, this option is not correct.
Based on the explanation above, we can conclude that none of the options (A, B, or C) are correct for both Tay-Sachs disease and Duchenne's muscular dystrophy.
