Question

Speculate about why enhancers are not part of transcription of bacterial genes.

Select the three correct answers.

-Enhancers often provide a mechanism for cell-specific transcription of genes, and most bacteria lack differentiated cell types. -The high level of mutation in bacterial genomes would likely alter these conservative sequences rendering them -nonfunctional. -Bacterial operons make coordinate regulation of protein synthesis by enhancers unnecessary. -Bacteria mostly regulate gene expression at the level of translation, making transcription enhancers unnecessary. -There is little to no intergenic space on bacterial chromosomes, which makes long-range-acting enhancer sequences unnecessary.

Explanation / Answer

Answer

Enhancers are DNA sequences that increase the rate of transcription. Enhancers act as binding sites for transcription factors that stimulate the transcription of one or more genes and enhancers stimulate transcription for specific cell type or tissue in a specific manner. The possible reasons for the lack of enhancers in bacteria include.

Therefore, the correct options are (a), (c), and (e).
