Biology Question on Principles of Inheritance and Variation
Mendel obtained wrinkled seeds in pea due to deposition of sugars instead of starch. It was due to which enzyme
A
Amylase
B
Invertase
C
Diastase
D
Absence of starch branching enzyme
Answer
Absence of starch branching enzyme
Explanation
Solution
Mendel obtained wrinkled seeds in pea plants due to the absence of starch branching enzyme, not because of an enzyme itself. Starch branching enzyme plays a role in the formation of amylopectin, which is a component of starch. In the absence of this enzyme, sugars are not properly branched and stored as starch, resulting in the accumulation of sugars and the formation of wrinkled seeds. So, the correct choice is (D): Absence of starch branching enzyme
