NEET BIOLOGY

Detailed explanation-1: -The nuclear envelope separates the contents of the nucleus from the cytoplasm and provides the structural framework of the nucleus. The nuclear membranes, acting as barriers that prevent the free passage of molecules between the nucleus and the cytoplasm, maintain the nucleus as a distinct biochemical compartment.

Detailed explanation-2: -Answer and Explanation: The nuclear membrane is not a component of all cells. Nuclear membranes are only found on the cells of organs called eukaryotes.

Detailed explanation-3: -The nucleus controls all of the cell organelles, whether it be the mitochondria, endoplasmic reticulum, ribosomes, cytoplasms, or even the nucleolus. So if the nucleus was removed, since it controls all of the organelles, the cell would die and so would the organism it is controlling.

Detailed explanation-4: -Cells which have nuclear components without any nuclear membrane are known as prokaryotic cells.

Detailed explanation-5: -The nuclear envelope (NE) is a highly regulated membrane barrier that separates the nucleus from the cytoplasm in eukaryotic cells. It contains a large number of different proteins that have been implicated in chromatin organization and gene regulation.
