WebMarieb/Brady/Mallatt. • Gene transcription can be positively or negatively regulated by proteins. • Functionally related genes of bacteria are organized in operons under coordinated control. • Transcription factors and other proteins bind to DNA and affect the rate of initiation of transcription at the promoter of eukaryotic genes. Webbecause of its larger size, the replication rate of eukaryotic genomes is significantly faster than the replication rate of bacterial and archaeal genomes false bacterial chromosomes, unlike eukaryotic chromosomes, often consist of a single replicon ture
WebAug 7, 2009 · Operons (clusters of co-regulated genes with related functions) are common features of bacterial genomes. More recently, functional gene clustering has been reported in eukaryotes, from yeasts to filamentous fungi, plants, and animals. Gene clusters can consist of paralogous genes that have most likely arisen by gene duplication. Webtwo different types of eukaryotic operon. Polycistronic transcription in eukaryotes was first found in 1988 in trypanosomes, although these polycistronically-transcribed genes do not …
