2. Researchers were interested in a human syndrome characterized by short stature, hearing loss, premature aging and photosensitivity. Panel A shows the effect of UV on fibroblast survival. Panel B shows the effect of UV on lymphoblast replication. Panel C shows the effect of UV dose on unscheduled DNA synthesis (UDS), which is DNA synthesis that occurs at times other than S-phase. Ignore panel D. Based on these results, generate a possible hypothesis the molecular cause of this syndrome. Name one protein that could be involved and design experiment to test its involvement. Be sure to include appropriate controls.
