structure information is available, and progress has been made in the functional characterization of the Na, K-pump, making the answer to this question possible, within reach of currently used techniques Prokaryotic Gene Expression Simon Baumberg 1999-05-27 Prokaryotic gene expression is not only of theoretical interest but also of highlyThe answer: different gene regulation! Gene regulation is how a cell controls which genes, out of the many genes in its genome, are “turned on” (expressed). Thanks to gene regulation, each cell type in your body has a different set of active genes – despite the fact that almost all the cells of your body contain the exact same DNA.For bacteria, the initiation of transcription is the most important point of control. Transcription regulator proteins bind short stretches of DNA called regulatory DNA sequences. Transcription regulators bind to regulatory DNA sequences close to where RNApol binds. Binding can activate or repress gene (s) transcription.

First, gene expression requires transcription , the process of making a messenger ribonucleic acid (mRNA) copy of the deoxyribonucleic acid (DNA) gene. Transcription can only occur if RNA polymerase first attaches, or binds, to the DNA.In prokaryotes, a combination of activators and repressors determines whether a gene is transcribed. As you know, prokaryotic organisms are fairly simple organisms with much less DNA . Prokaryotic genes are arranged in operons , a region of DNA with a promoter, an operator , and one or more genes that encode proteins needed to perform a certain ... The DNA of prokaryotes is organized into a circular chromosome supercoiled in the nucleoid region of the cell cytoplasm. Proteins that are needed for a specific function are encoded together in blocks called operons.

1982;4 (1-2):9-29. Gene expression in eukaryotes is influenced by a wide variety of mechanisms, including the loss, amplification, and rearrangement of genes. Genes are differentially transcribed, and the RNA transcripts are variably utilized. Multigene families regulate the amount, the diversity, and the timing of gene expression.
