How can two different transcriptomes be studied with a single microarray? Select one: a. One transcriptome is hybridized and studied first and then its sequences are removed and the second transcriptome is studied on the same microarray b. Only one of the transcriptomes is labeled and it competes with the second, unlabeled transcriptome for binding to the probe sequences c. The transcriptomes are hybridized to each other prior to the microarray analysis to remove cDNA present from both c types X d. The two transcriptomes are labeled with different fluorescent probes and hybridized simultaneously How can transcriptome studies aid in the diagnosis of human cancer? Select one: a. All cancers exhibit the increased expression of a specific set of genes b. Each cancer possesses its own unique transcriptome c The genes that cause tumors are not expressed in healthy cells d.
