BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION
342182
In his experiments, Mendel obtained wrinkled pea. The wrinkling was due to deposition of sugar instead of starch. This happened due to the?
1 Amylase enzyme
2 Absence of starch branching enzyme
3 Invertase enzyme
4 Diastase enzyme
Explanation:
The wrinkling of pea was due to deposition of sugar instead of starch because sugar synthesized gets accumulated in peas as there is no starch branching enzyme. This is due to disruption of biochemical process for making starch in the peas. Starch branching enzyme (SBE-1) is absent in wrinkled seeds. As wrinkled seeds can convert only less amount of sugar into starch and this causes accumulation of sugar in them. Hence, they are sweeter than the round peas.
