Only $(2)$

Vedclass · Answer

(C) $(1)$ Meiosis involves a single cycle of $DNA$ replication,which is correct.$(2)$ At the end of Meiosis-$I$,two haploid cells are formed,not four. Four haploid cells are formed only after the completion of Meiosis-$II$. Thus,statement $(2)$ is incorrect.$(3)$ Mitosis can occur in both haploid and diploid cells (e.g.,in some lower plants and social insects). Thus,statement $(3)$ is incorrect.$(4)$ In yeast,the cell cycle takes approximately $90$ minutes to complete,which is correct.Therefore,statements $(2)$ and $(3)$ are incorrect. Since the options provided do not explicitly list $(2)$ and $(3)$,and the question asks to identify incorrect statements,we evaluate the provided options. Given the standard interpretation,$(2)$ is definitely incorrect. If the question implies selecting the set of incorrect statements,and $(2)$ and $(3)$ are both incorrect,the most appropriate choice based on the provided options is $(C)$ if we consider only $(2)$ as the primary error,or we identify that the question structure requires selecting the incorrect ones.

Column $X$	Column $Y$
$(1)$ Tetrad	$(P)$ Zygotene stage
$(2)$ Chiasmata	$(Q)$ Diplotene stage
$(3)$ Splitting of centromere	$(R)$ Meiosis
$(4)$ Bivalent	$(S)$ Pachytene stage
	$(T)$ Anaphase
	$(U)$ Mitosis

Identify the incorrect statements:
$(1)$ Meiosis involves only a single cycle of $DNA$ replication.
$(2)$ At the end of Meiosis-$I$,four haploid cells are formed.
$(3)$ Mitosis is generally restricted to diploid cells.
$(4)$ In yeast,the cell cycle takes approximately $90$ minutes to complete.
