WebProkaryotic DNA associates with histones. C. Eukaryotic DNA forms. 1. Eukaryotic gene expression is different from prokaryotic expression in which of the following ways? A. Eukaryotes have operons. B. Prokaryotic DNA associates with histones. C. Eukaryotic DNA forms chromatin. WebSome of these gene clusters were observed in eukaryotes, as affecting Drosophila morphology 1, 2, or biosynthetic pathways in Aspergillus [3] or Neurospora [4]. Clusters of functionally-related genes, however, are unusual in eukaryotes and many clusters were actually alleles of the same locus (eukaryotic operons are discussed further below).
