Recall how T-cells are able to control transcription by NF-AT by trafficking NF-AT into and out of the nucleus. In an activated, T-cell NF-AT enters the nucleus. As the T-cell becomes deactivated, most of the conditions below must be met for NF-AT to exit the nucleus. Which choice below is NOT a condition for its exit? A. NF-AT must be bound to the export receptor B. Calcineurin must be bound to NF-AT C. NF-AT must display a nuclear export sequence D. Ran-GTP must be bound to the export receptor

Question

		Donor blood contains stem cells that regenerate cells in the immune system
		Bone marrow contains induced pluripotent stem cells that turn into red blood cells
		Bone marrow contains tumor supressor genes that slow down leukemia growth
		Bone marrow contains pluripotent human embryonic stem cells

		Increased genomic instability would result from adding foreign nucleic acids
		New mutations would arise in the oncogene
		The oncogene would be converted back into a proto-oncogene
		The siRNAs would compete with the oncogene's active site
		Production of the oncogene protein would decrease

		The enzymes control the rate of translation of an mRNA transcript
		The enzymes add phosphate or methyl groups to histone tails
		The enzymes slide nucleosomes farther apart or closer to each other
		The enzymes send damaged proteins to the proteasome for degradation
		The enzymes cause DNA looping to occur
