Solution

Correct Answer: E : Actually, all of these are involved in the transcriptional control of RNA polymerase II.

Explanation:

Transcription control is also known as \"sequence specific DNA binding control\". It is a factor that controls the rate of transcription of genetic information from DNA to mRNA by cohering to a definite DNA sequence. In simple terms, transcription is a process that creates RNA molecule from a DNA sequence.

** RNA polymerase II includes all of the below regulatory sequences:

1. TATA Box: It\'s a promoter sequence or a DNA sequence that shows where a genetic code can be read or can be decoded, during transcription.

2.The core promoter: Basically, promoter of protein-coding genes in living cells.

3. Regulatory Promoter: It controls the abundance changes in the regulatory proteins of the cells. Basically, promoter, operator and enhancer helps to control the transcription of genes into an mRNA

4. Enhancer : It\'s a short region of DNA/ non-coding DNA sequence that can be bound by proteins. Enhancer contact the promoter dependently of the core DNA binding and can regulate more than one genes without restriction. Helps to interact with general transcription factor and RNS polymerase II.
