RBC’s don’t have nuclei
What type of image is this?
Identify nm, c, n, and f


Compartmentalization of Nucleus
Compartmentalization of Nucleus allows us to control reactions in comparison to those in the cytoplasm.
Are there any organelles in the Nucleus?
No Organelles in the nucleus
Nucleolous is where…
Nucleolus = Where ribosomes are synthesized.


How Can we determine the location of proteins and whether or not they are inside or outside the nucleus?

What is the function and Structure of the Nuclear Lamina?

Describe the structure of what’s in the image.


What are lamin associated diseases?
Mutations in different lamins lead to different disease.

Central Granual

Central Granual is a filler in the middle of the pore. Some pores have channels some have central granule.
