Why Do Max/Max Homodimers Convert to Myc/Max Heterodimers in the Presence

Multiple Choice

Why do Max/Max homodimers convert to Myc/Max heterodimers in the presence of Myc protein?

A) Myc has a higher affinity for Max than Max has for Max.
B) Myc more tightly associates with DNA,thus recruiting Max monomers to the enhancer.
C) The enhancer element being regulated only associates with Myc/Max heterodimers.
D) Max is rapidly degraded in the presence of Myc.
E) Myc/Myc homodimers are rapidly degraded in the presence of Max.
