Double nuclear envelope |
To enclose and protect DNA |
|
|
Nuclear pores |
Allow entry of substances like nucleotides for DNA replication and exist of mRNA molecules in protein synthesis |
|
|
Nuclear pores plugged by an RNA/protein complex |
Small molecules pass through pores by diffusion, whereas large molecules like partly completed ribosomes pass through actively |
|
|
Nucleoplasm contains chromatin granules made of DNA and associated proteins |
During cell division condense and form chromosomes |
|
|
Nucleoplasm contains nucleoli |
Produces partly completed ribosomes, co-enzymes, nucleotides, proteins and RNA molecules |
|
|
The outer membranes of the nuclear envelope has rough ER membrane |
Makes the peri nuclear space continuous with the lumen of the ER thus allowing easy transport of substances |
