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
