Vedclass · Answer

(A) The nuclear envelope consists of two parallel membranes with a space between them called the perinuclear space.These membranes are interrupted by minute pores,known as nuclear pores,which are formed by the fusion of the two membranes.These nuclear pores act as passages for the movement of $RNA$ and protein molecules in both directions between the nucleoplasm and the cytoplasm.Therefore,both the statement $(S)$ and the reason $(R)$ are correct,and $R$ is the correct explanation of $S$.

$S$ - Statement: $RNA$ and protein molecules move between the nucleoplasm and the cytoplasm.
$R$ - Reason: Nuclear pores are present at several locations in the nuclear envelope of the nucleus.
