2. During transcription, why is information from DNA copied onto RNA?
- RNA would be wasted if it wasn't used
- DNA cannot obtain enough energy to properly deliver information to the other organelles and so it passes info onto RNA, which can gain enough energy to transfer the info
- DNA is too large to leave the nucleus so its information is copied onto RNA which is small enough to leave through the nuclear pores
- DNA is too important to leave the nucleus so RNA acts as a messenger delivering information to other organelles within the cell
3. Where are proteins synthesised?
- On the ribosomes bound to the endoplasmic reticulum
- Within the endoplasmic reticulim
- In the ribosomes that are found free floating in the cytoplasm
- In the cisternae of the golgi apparatus
4. In prokaryotic cells, the cell wall is made from...?
5. How is the size of ribosomes in prokaryotic cells determined?
- Its determined by the rate in which they settle or form a sedimate in solution
- Its random
- Its determined by the size of the cell
- Its determined by how many ribosomes are present
