2. What is the name of the dark region within the nucleus?

  • The nuclear sap
  • The nucleolus
  • The DNA
  • The premature nuclei

3. What are lysosomes?

  • External organelles that keep cells stationary
  • Specialised forms of vesicles containing hydrolytic enzymes (digestive enzymes)
  • Specialised digestive enzymes
  • Vesicles that play a key role in protein synthesis

4. During transcription, why is information from DNA copied onto RNA?

  • 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
  • RNA would be wasted if it wasn't used
  • DNA is too important to leave the nucleus so RNA acts as a messenger delivering information to other organelles within the cell

5. Where are proteins synthesised?

  • In the ribosomes that are found free floating in the cytoplasm
  • In the cisternae of the golgi apparatus
  • On the ribosomes bound to the endoplasmic reticulum
  • Within the endoplasmic reticulim
