Multiple Choice
In transcription, __________.
A
the promoter region acts as an initial binding site for RNA polymerase

only one of the DNA strands is used as the template
C

D
All of the answer choices are correct.
Verified step by step guidance1
Understand the process of transcription: Transcription is the first step in gene expression where a segment of DNA is copied into RNA by the enzyme RNA polymerase.
Identify the role of the promoter region: The promoter region is a sequence of DNA that initiates transcription. It acts as the binding site for RNA polymerase, allowing the enzyme to attach to the DNA and begin synthesizing RNA.
Recognize the use of DNA strands: During transcription, only one of the two DNA strands is used as a template. This strand is called the template strand, and it provides the sequence of nucleotides that will be transcribed into RNA.
Consider the source of RNA nucleotides: RNA nucleotides are the building blocks of RNA. These nucleotides are synthesized by the cell and are used during transcription to form the RNA strand complementary to the DNA template strand.
Conclude that all statements are correct: Each of the statements provided describes a key aspect of transcription, confirming that all the answer choices are correct.
