|
|
Haloenzyme
|
|
|
Sigma factor and core enzyme
|
|
|
RNA polymerase
|
Explanation:
Detailed explanation-1: -Specifically, in bacteria, sigma factors are necessary for recognition of RNA polymerase to the gene promoter site. The sigma factor allows the RNA polymerase to properly bind to the promoter site and initiate transcription which will result in the production of an mRNA molecule.
Detailed explanation-2: -RNA polymerase initiates transcription at specific DNA sequences called promoters.
