Vedclass · Answer

(B) The sequence of events during mitosis involves the structural changes of chromosomes:$1$. Initially,the $DNA$ replicates to form a Dyad $(3)$,which consists of two sister chromatids joined at the centromere.$2$. During metaphase/anaphase,the structure is referred to as a Chromatid $(1)$ when considering the individual strands.$3$. $A$ Monad $(2)$ represents a single chromosome structure before replication or after separation.$4$. Finally,after the separation of sister chromatids during anaphase,they are referred to as Daughter chromosomes $(4)$.However,in the context of the progression of chromosomal states during the cell cycle: $A$ chromosome exists as a Monad $(2)$ in $G_1$,becomes a Dyad $(3)$ after $S$ phase,the individual components are Chromatids $(1)$,and upon separation,they become Daughter chromosomes $(4)$.Therefore,the correct sequence is $2, 3, 1, 4$.

Column $I$	Column $II$
$(A)$ $G_1$-phase	$(i)$ Synthesis of proteins and microtubules
$(B)$ $S$-phase	$(ii)$ Growth phase
$(C)$ $G_2$-phase	$(iii)$ $DNA$ replication

Arrange the following events occurring during mitosis in the correct sequence: $(1)$ Chromatid,$(2)$ Monad,$(3)$ Dyad,$(4)$ Daughter chromosome.
