Labelled amino acids alanine and tryptophane were injected to a mouse in order to study localization of protein synthesis in its cells. The labelled amino acids will be accumulated near the following organellas:
- A. Ribosomes
- B. Cell centre
- C. Lysosomes
- D. Golgi apparatus
- E. Smooth endoplasmic reticulum
Hint
Radioactive amino acids are building blocks, so ask which structure uses them directly and which structures only handle proteins after they have been made.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
