1
Q

Structure of the nuclear envelope

A
  • Separates nucleus from cytoplasm
  • Home to transcription and RNA progressing in Eukaryotes
  • Consists of inner, outer membranes and lamina
2
Q

Nuclear Pore Complex

A
  • Only routes into the nucleolus
  • Small molecules diffuse freely
  • macromolecules are selectively transported to nucleolus or cytoplasm
3
Q

Selective Transport of proteins to and from nucleus

A
  • Contain localization signals recognized by pore receptors

- Protein named Ran determines direction and movement through the pores

4
Q

Transport of RNA

A

mRNA, ribosomal RNA and transfer RNA are exported from nueclous for protein synthesis

5
Q

Chromosome organization and gene expression

A
  • Interphase nucleolus with transcriptionally inactive hetero chromatin
  • chromosomes occupy distinct territories
6
Q

Endoplasmic reticulum and protein secretion

A

Proteins for secretion, lysosomes or plasma membrane are transferred to rough ER

7
Q

Organization of the Golgi

A
  • Protein processing and sorting

- From Ed to cis Golgi to Golgi network
