Concept explainers
(a)
To determine: The advantage of the arrangement of bacterial genes with related functions in operons that are under the control of a single promoter.
Introduction: The bacterial genome is small with 500-5000 genes that are organized in clusters known as operons. These contain functional coregulated genes and regulatory sequences.
(b)
To determine: How eukaryotic cells that do not contain operons ensure the simultaneous transcription of different genes.
Introduction: Transcription process marks the beginning of gene expression. In eukaryotes, transcription factors are the proteins that function in transcribing DNA to mRNA. Specific transcription factors bind to the control elements of enhancers and promote transcription.
