Chapter 16, Problem 13TYK

Summary Introduction

To review:

Developing a hypothesis to explain that the muscle samples from women, who carry a mutation for muscular dystrophy disease, reveal some regions of degenerating muscle tissue adjacent to the other regions that are normal.

Introduction:

Duchenne muscular dystrophy is an example of the X-linked recessive disorder. Cells have DMD (Duchenne muscular dystrophy) gene, which produces a protein-dystrophin in muscle cells. Dystrophin provides the strength to the muscle tissues. Mutation in the DMD gene causes the muscle tissues to break down and thus, weak muscles are formed.
