Question 14 Friedreich's ataxia is a rare inherited disease that causes nervous system damage and movement problems. It usually begins in childhood and leads to impaired muscle coordination (ataxia) that worsens over time. Friedreich's ataxia is caused by an insertion of several copies of a three nucleotide sequence in a gene called FXN. Which genetic testing method would be most appropriate for testing for Freidreich's ataxia? O PCR with gel electrophoresis O PCR with conventional sequencing O PCR with SNP-chip O PCR with whole-genome sequencing
QUESTION 5 WHAMM is a nucleation promoting factor. Depicted above is a pyrene actin polymerization assay performed with the following reaction conditions 1: Actin + Arp2/3 + WHAMM (active isoform); 2-5: Actin + Arp2/3 + WHAMM (active isoform) and increasing concentrations of Rab1; or 6: actin alone. What effect does Rab1 have on branched actin polymerization? Actin + Arp2/3 + 1.0 500nM WHAMM + 0.2x Rab1(M) + 1.0x Rab1(M) + 2.0x Rab1(M) + 3.0x Rab1(M) Actin alone 0.5 0.0 1000 2000 Time (s) Enhances WHAMM activity inhibits WHAMM activity No effect induces actin bundle formation F-actin (RFU)
