Question 1

'RNAi' stands for which of the following?

Question 2

Andrew Fire and Craig Mello won a Nobel Prize in 2006 for their work, begun in the late 1990s, on RNA interference. Which of the following organisms did they work on?

Question 3

Suppose a certain gene contains the double-stranded sequence:
5'- ATGTTTAGCGCC -3'
3'- TACAAATCGCGG -5'
If the the top strand is the sense strand and codes for a mRNA whose sequence begins 'ATG'. Which of the following would be the sequence of the corresponding segment of antisense RNA?

Question 4

The effectors of gene silencing are short double-stranded RNA molecules produced by the action of the enzyme dicer. Approximately what size are these molecules?

Question 5

There are hopes that RNA interference will have a wide range of therapeutic applications. It may be possible to use microRNAs to silence oncogenes. Which of the following is caused by oncogenes?
