Answer:
c. glycogen molecules with branches containing a single glucose residue
Explanation:
The mutation inhibits the activity of the glucosidase but does not affect the other functions of the enzyme. The researcher then introduces the mutated enzyme into mammalian cells that do not express wild type glycogen debranching enzyme because glycogen molecules with branches containing a single glucose residue (single glucose molecule linked by alpha 1,6 linkage due to mutation in glucosidase activity of debranching enzyme).
