1. Identify and describe the functions of the nuclear envelope

2. Describe the structure of the nuclear envelope.

3. Analyze how Lamin proteins play a role in nuclear structure.

Solutions

Expert Solution

1)-function of nuclear envelope -The nuclear envelope surrounds the nucleuswith a double membrane with multiple pores. The pores regulate the passage of macromolecules like proteins and RNA, but permit free passage of water, ions, ATP and other small molecules.

2)-structure of nuclear envelope- the nuclear envelope is composed of two concentric lipid bilayer membranes separated by intermembrae space. It is double membrane structure.

3)-the lamin protein provides support for maintaining the shape of the nucleus.
