Answer:

The correct answer is option d. RNA polymerase binds to a promoter region of DNA

Step-by-step explanation:

Hello!

We will answer that!

The process of transcription consists in the transformation of DNA into RNA from a DNA sequence.

At the beginning of the process the DNA opens in a promoter region and the RNA polymerase enzyme binds to begin transcription. The promoter region is a sequence of nucleotides in the DNA that indicate that the enzyme has to bind there.

So, the correct answer is option d. RNA polymerase binds to a promoter region of DNA

To complete our analysis we can say that the following options are arranged as follows:

c. Nucleotides are covalently linked together: all DNA nucleotides are linked with a covalent bond

b. RNA polymerase reaches a terminator region: when RNA polymerase reaches the terminator region, we have premature RNA

to. Introns are edited out of the premature RNA ..

The answer is RNA polymerase binds to a promoter region of DNA.

A promoter region of DNA is the site of initiation of gene transcription. For transcription to start, firstly, RNA polymerase must bind to a promoter region of DNA. RNA polymerase is an enzyme responsible for a synthesis of RNA and it enables nucleotides to covalently link together. When RNA polymerase reaches a terminator region, premature RNA frees. Further, introns are edited out of the premature RNA, and mature RNA is synthesised.
