How are eukaryotic genes organised

WebNational Center for Biotechnology Information WebIn prokaryotes, structural genes of related function are often organized together on the genome and transcribed together under the control of a single promoter. The operon’s regulatory region includes both the promoter and the operator. If a repressor binds to the operator, then the structural genes will not be transcribed.

Web3 de jan. de 2024 · B. Complexities of Eukaryotic Gene Regulation. Gene regulation in eukaryotes is more complex than in prokaryotes. This is in part because their genomes are larger and because they encode more genes. For example, the E. coli genome houses about 5,000 genes, compared to around 25,000 genes in humans. Furthermore, … WebAlthough eukaryotic genes lack operons, ... Genes in prokaryotes are organised in operons, DNA sections containing a promoter, an operator, and one or more genes that encode proteins required for a specific purpose. Lac operon regulation is a good example of bacterial gene regulation.
