Explanation:
Detailed explanation-1: -Nuclear pore complexes allow the transport of molecules across the nuclear envelope. This transport includes RNA and ribosomal proteins moving from nucleus to the cytoplasm and proteins (such as DNA polymerase and lamins), carbohydrates, signaling molecules and lipids moving into the nucleus.
Detailed explanation-2: -The outer membrane is also continuous with the inner nuclear membrane since the two layers are fused together at numerous tiny holes called nuclear pores that perforate the nuclear envelope.
Detailed explanation-3: -DNA Biology The mRNA leaves the nucleus through nuclear pores and travels to a ribosome.
