The information in the passage suggests that in mice CRY1 most likely affects XPA by: A.activating XPA protein activity. B.activating translation of XPA-encoding transcripts. C.repressing replication of the XPA-encoding gene. D.repressing transcription of the XPA-encoding gene. passage: the nucleotide excision repair system (NER) recognizes, removes, and replaces segments of DNA strands that contain CPDs and (6-4) PPs. Figure 1 shows how mouse skin levels of XPA (a damage-recognition an...

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.
