Gene regulation in eukaryotes

The basis of the technology zfps represent the most common dna-binding motif in eukaryotes and are found in many transcription factors sangamo's engineered zfp transcription factors (zfp tfs) are built to mimic the natural mode of gene regulation. Gene regulation in prokaryotes in bacteria and archaea prokaryotic operons are excellent models for learning about gene regulation generally there are some gene clusters in eukaryotes that function similar to operons. Gene regulation differs between prokaryotes and eukaryotes in a few ways there are multiple ways gene regulation differs between prokaryotes and eukaryotes prokaryotics don't have a nucleus but eukaryotics do (see image below) so transcription and its regulation in prokaryotics is much simpler.

There are many differences between prokaryotic and eukaryotic cells some of these differences are structural whereas others are procedural two of the processes that are substantially different between prokaryotes and eukaryotes are gene expression and the regulation of it. Best answer: d is correct gene regulation in eukaryotes is significantly more complex than it is in prokaryotes, involving a large number of mechanisms that prokaryotic organisms simply don't have, so a is false b and c both speak about operons, which are clusters of several genes that all.
