Question
A student after viewing a prepared slide illustrates the budding in yeast in the following order which is not correct:
(A) b, c, d, e, a
(B) b, e, d, c, a
(C) b, d, e, c, a
(D) b, d, c, e, a
Solution
During budding in yeast, a single cell develops a protrusion wherein the nucleus divides to give rise to two daughter nuclei. One of the daughter nucleus migrates into the protrusion to form a bud. This bud then enlarges in size and may undergo budding while attached to the parent cell. Hence, budding results in a chain of cells.
The correct answer is D.
