The genetic expression shows the process of the genetic makeup of an organism as its physical traits. Prokaryotic gene expression (both transcription and translation) occurs within the cytoplasm of a cell due to the lack of a defined nucleus; thus, the DNA is freely located within the cytoplasm. In prokaryotes, there are examples of operons whose gene products are required rather consistently and whose expression, therefore, is unregulated. In some cases, the cells interact with each other or their environment to regulate gene expression. Biology 210 GENETICS 6 April, 1998. Because prokaryotic organisms lack a cell nucleus, the processes of transcription and translation occur almost simultaneously. Transcriptional Regulation of Gene Expression in Eukaryotes: The variation in the rate of transcription often regulates gene expression. Scribd is the … prokaryotes and eukaryotes is considered their genome. Gene Expression in Prokaryotes. prokaryotes and eukaryotes is considered their genome. Hence, the rest of this article deals exclusively with prokaryotes. Lodish et al. Coexpression of genes or, more generally, similarity in the expression profiles poses an unsurmountable obstacle to inferring the gene regulatory network (GRN) based solely on data from DNA microarray time series. 19 EUKARYOTIC GENOME.ppt.
