Question

Duchenne muscular dystrophy is an X-linked recessive disorder caused by the lack of dystrophin which causes ____ to leak into muscles cells which then dissolve to be replaced by fibrous connective tissue.

Answer 1

Answer: The answer is Calcium.

Step-by-step explanation:

Duchenne muscular dystrophy is an X-linked recessive inheritance disorder that is passed from the mother (the carrier) to the child, mostly the male. It is a disorder of progressive muscular weakness. Those who inherit it have a defective gene related to dystrophin which is a muscular protein. The gene that makes Dystrophin is broken and the muscles become weak. Calcium molecules also build up in the muscles.

This causes muscle weakness, frequent falls, trouble running or climbing the stairs and dependency on wheel chairs.
