A student was given two permanent slides, one of binary fission in amoeba and other of budding in yeast. He was asked to identify any one difference in the
nucleus of the two. One such difference, he identified correctly was (1) Presence of one nucleus in amoeba, two in yeast cell and one in bud. (2) Presence of two nuclei in centrally constricted amoeba, one in yeast cell and one in its bud. (3) Presence of two distant nuclei in amoeba, one in yeast cell and two in bud. (4) Presence of a single nucleus each in amoeba, yeast cell and its attached bud.
