Mendel obtained wrinkled seeds in pea due to deposition of sugars instead of starch. It was due to which enzyme :-A. amylaseB. invertaseC. diastaseD. absence of starch-branching enzyme |
Answer» Correct Answer - D In round seeds `(R R//Rr)` Starch-Branching Enzyme-1 (SBE-1) 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. |
