Identify the regions of the transcription unit. (a) Promoter (b) Sigma factor (c) Terminator (d) The structural gene Choose the correct answer from the options given below:

🔑Key Points:
This means the regions of the transcription unit include the Promoter, Terminator, and the Structural Gene.
-The Promoter is a region of DNA that initiates transcription of a particular gene. It is where the RNA polymerase binds to start transcription.
-The Terminator is a sequence of nucleotides in DNA that marks the end of a gene or operon in genomic DNA during transcription.
-The Structural Gene consists of the DNA sequence that is actually transcribed into RNA, which may then be translated into a protein.

🔴Additional Information:
-Sigma factor is not part of the DNA sequence of the transcription unit but rather a protein needed for the initiation of transcription in bacteria. It helps the RNA polymerase to bind to the promoter.
