1. Are non-dividing cells more vulnerable to damage than dividing cells? Why is this the case? 2. What is the average age for most proteins in the body? Does this surprise you? Why or why not? How does this situation benefit organisms by recycling elements?
3. Do you think the fact that some proteins last longer than others mean that some proteins are more important than others, or is how long a protein lasts just a reflection of its function in the body? Explain your thinking as thoroughly as possible.
4. How do researchers hope to understand healthy aging by the study of proteins?
5. What are ELLP's? Where have they been identified to occur in a rat's central nervous system? Why does this suggest they may have unique importance in organisms?
