CBT QUESTIONS AND ACCURATE PASSED ANSWERS 2023/2024 Which one of the following statements correctly describes what happens after Wnt ligand binds to Frizzled and LRP? a. RAR-RXR heterodimers are formed and associate with HDAC co-repressor complexes, silencing target genes. b. Axin and APC form a complex with CKI and GSK3β which then modifies β-catenin for degradation. c. Axin is recruited to the phosphorylated co-receptor LRP and this disrupts the APC, CKI, GSK3β complex. d. Patched ...
