In this video, I look at the nuclear envelope, an essential structure that encases the nucleus of a cell. The nuclear envelope, comprising inner and outer membranes, and plays a critical role in safeguarding fragile DNA and regulating the internal environment of the nucleus.

Key Points Covered:

1. Structure of the Nuclear Envelope:
Composed of inner and outer membranes collectively referred to as the nuclear envelope.
Provides a protective barrier for DNA against mechanical stresses during cell movement and division.

2. Functions of the Nuclear Envelope:
Regulates the internal environment of the nucleus.
Controls what enters and exits the nucleus.
Enables the processing of mRNA within the nucleus before translation, ensuring proper protein synthesis.

3. Role of the Nuclear Lamina:
Acts as the nucleoskeleton, protecting DNA from mechanical stresses exerted by the cytoplasm.

4. Challenges Posed by the Nuclear Envelope:
Must be disassembled during cell division.
Presents a barrier for the transport of molecules, addressed by nuclear pores.
