Method which is utilized by eukaryotes to control their gene expression that is different from the type of control found in bacteria is control of both RNA splicing and chromatin remodeling.

Explanation:

There is a difference in the gene expression of the prokaryotes and eukaryotes. In prokaryotes, transcription and translation occur simultaneously in the cytoplasm, and gene regulation occurs at the transcriptional level. In eukaryotes gene expression is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm.

Prokaryotic cells can only regulate gene expression by controlling the amount of transcription. As eukaryotic cells evolved, the complexity of the control of gene expression increased. For example, with the evolution of eukaryotic cells came compartmentalization of important cellular components and cellular processes. A nuclear region that contains the DNA was formed. Transcription and translation were physically separated into two different cellular compartments. It therefore became possible to control gene expression by regulating transcription in the nucleus, and also by controlling the RNA levels and protein translation present outside the nucleus.
