Answer:
The membranes of the endoplasmic reticulum are continuous with the membranes of the nuclear envelope.
Step-by-step explanation:
The nuclear envelope of a eukaryotic cell, also called nuclear membrane, divides or separates the nucleus from the cytoplasm. It consists of an inner membrane and an outer membrane that helps the nucleus to maintain the all its contents inside, such as the DNA, while also providing protection by preventing other substances from entering.
The membranes of the nuclear envelope are continuous with the membranes of the rough endoplasmic reticulum. According to researchers, the nuclear envelope and the endoplasmic reticulum are in a state of equilibrium. For instance, when damage to the membrane of the nuclear envelope occurs, the endoplasmic reticulum can develop additional membrane continuities to support it.
