Question

DNA is comprised of smaller segments of genes that code for the production of a specific protein. The role of RNA polymerase in the initiation step of transcription is to

determine where gene synthesis will start.

all of the above

bind and unwind the double helix.

recognize the promoter sequence of the gene.

Answer 1

Answer:

all the above

Explanation:

all the above

Answer 2

Transcription is defined as the formation of messenger RNA (mRNA) from DNA template.

Explanation:

The main enzyme participates in transcription is RNA polymerase. It performs many roles such as-

• it binds to template strand of DNA and begins the transcription.
• it unwinds the double helix
• it also recognizes the promoter sequence of the gene.

RNA polymerase binds to the promoter of the DNA template to begin the transcription.

So, the correct option is All of the above.
