1. Is this a spotted cDNA array or an oligonucleotide array?
2. Is this a one-colour or two-colour array?
3. How is this exon array different to a 3’UTR array?
4. Considering the function of Tardbp, why do you think it was advantageous to use exon arrays to analyse transgenic mice that have a mutation in Tardbp?
5. Besides frontotemporal dementia, what other human disease is this mouse a model for?
6. This analysis could have been performed using RNA-seq. List two advantages and two limitations of RNA-seq compared to microarray analysis.
7. Bonferonni correction has been selected, why is this important?
8. This is a GO-Slim analysis of the Biological Process category. What does this mean?
