5 Multiple Choice Questions
- The addition of a sugar (carbohydrate) onto both protein and membrane
- Ribosomes are attached to it
- Because RNA contains instructions to do so (before synthesizing the protein it is assigned to make, ribosome has to bind to the ER.
- Yes, unless RNA of protein has "signal sequence"
- Simultaneous polymerization and depolymerization of different microtubules within same population at steady state
5 True/False Questions
What are the other two tubular structures besides "actin filaments"? → Intermediate filaments and microtubules
What happens if protein doenst have "signal sequence"? → Translation of protein stops until ribosome docks on ER. Once docked, the protein is "extruded" into ER cotranslationally (inserted). Protein then folds in ER and moves to Golgi Apparatus, which addresses it to its final destination.
What's special about intermediate filaments? → none
What motors operate on intermediate filaments? → Skin, muscle, hair/nails
What are microtubules' motors? → Kinesin and dynein
