Detailed explanation-1: -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.
Detailed explanation-2: -The nuclear membrane is a double layer that encloses the cell’s nucleus, where the chromosomes reside. The nuclear membrane serves to separate the chromosomes from the cell’s cytoplasm and other contents.
Detailed explanation-3: -In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope. This envelope safeguards the DNA contained in the nucleus.
Detailed explanation-4: -The nuclear envelope is also called nuclear membrane, is a double membrane layer that separates the contents of the nucleus from the rest of the cell. It is a barrier that physically protects the cells DNA from the chemical reactions that are occurring elsewhere in the cell.
