A) amylase
B) invertase
C) diastase
D) absence of starch-branching enzyme
Correct Answer: D
Solution :
In round seeds (RR/Rr) starch-branching enzyme (SBE-I) is found but is absent from wrinkled seeds. In rr seeds, a small DNA segment interferes with SBE-1 activity so that starch is not formed and free sugar gets accumulated. Resulting high osmotic pressure in rr seeds leads to shrinkage and wrinkling.You need to login to perform this action.
