Question

Quizplus · Accepted Answer

The nuclear lamina is a dense fibrillar network inside the nucleus of most cells, composed of intermediate filaments and membrane-associated proteins. It provides mechanical support, helps organize chromatin, and regulates important cellular events such as DNA replication and cell division. It is indeed located on the inner surface of the nuclear envelope, supporting the nuclear membrane and playing roles in nuclear structure and dynamics.
