Self chosen article:

- Why is this organism chosen for this research question

- Why is this organism chosen instead of another model organism

- Do you agree with the choice of the author

- Knowing the results, what technique or method would you add to this research

- Give 2 arguments why this organism is a model organisms.

Theoretical question:

- Explain terminator seeds

- After doing a forward screening in C. elegans, they found mutants with altered body length. Explain the strategy how you can know the causal mutations. Can you perform this stragety in other organisms and which step is important for causality?

- Explain morpholinos and compare with other similar technique.

What is a polytene chromosome and how is it used for genetics? (Extra questions: Why was it easier to have this to study genetics, answer because it is much bigger thanks to endoduplication which means that you can see it under a microscope. If you would have found a piece of the chromosome and you can sequence it, how can you find where it is located on the polytene chromosome, answer was in situ hybridisation [You can't answer CRISPR or something like that because it didn't exist back then].)

ES technology, any alternatives?
