Question

During transcription, the DNA site at which RNA polymerase binds is called:
A. Enhancer
B. Promoter
C. Regulator
D. Receptor

Answer 1

Hint: The primary goal of transcription is to create an RNA copy from the DNA sequence. The RNA transcript transmits the data often used to encode a protein. RNA polymerase is the key enzyme that participates in transcription.
Complete step by step solution:
Enhancers are gene expression regulatory DNA sequences that enhance the activity of a promoter in orientation, position, and distance-independent manner. In eukaryotic organisms, such sequences perform a significant role in the control of tissue-specific expression of genes.
A promoter is a DNA sequence that would be necessary to switch a gene on or off. The transcription program commences at the promoter. The promoter, which is usually found close to the beginning of a gene, contains a binding site for the enzyme that is employed to make a messenger RNA (mRNA) molecule. Thus, the site at which DNA polymerase binds throughout the transcription possess can be referred to as
A regulator gene is one that regulates the expression of one or several other genes. A receptor is a protein that binds to a particular molecule. The ligand is the molecule to which it binds. The ligand ties to the receptor protein's ligand-binding site. Whenever this binding occurs, the receptor changes conformation.

Hence, the correct option is B

Note:
A regulator gene is one that creates a biochemical that inhibits the activity of the operator gene. The promoter gene is the gene that offers the linkage point to RNA polymerase needed for structural gene transcription.
