שאלה | You performed hierarchical clustering on a gene expression matrix and found that Cluster X consists of genes that are highly expressed in immune-related conditions but show low expression in cancer samples. Question: Which of the following hypotheses best explains this observation?

You performed hierarchical clustering on a gene expression matrix and found that Cluster X consists of genes that are highly expressed in immune-related conditions but show low expression in cancer samples. Question: Which of the following hypotheses best explains this observation?

		Cluster X contains genes involved in cell cycle regulation.
		These genes are unrelated to disease processes and likely represent noise.
		The clustering algorithm failed to correctly separate the cancer samples.
		Cluster X is likely composed of genes involved in immune surveillance, which may be suppressed in cancer.
