Question

DNA-dependent RNA polymerase catalyzes transcription on one strand of the DNA which is called the
A. Alpha strand
B. Antistrand
C. Template strand
D. Coding strand

Answer 1

Hint: Transcription is explained as the synthesis of RNA from the DNA. The Genetic information flows from DNA into protein, protein is the substance that gives an organism its form.

Complete answer:
 The flow of information occurs through the sequential processes of transcription (DNA to RNA) and translation(RNA to protein).
Transcription occurs when there is a need for a particular gene product at a specific time or in a specific tissue.
A RNA polymerase (RNAP), or ribonucleic acid polymerase, is known as a multisubunit enzyme that catalyzes the process of transcription where an RNA polymer is synthesized from a DNA template.
 The sequence of the RNA polymer is complementary to that of the template DNA and is synthesized in a 5’→ 3′ orientation. This RNA strand is called the primary transcript and needs to be processed before it can be functional inside the cell.
The template DNA strand which is served in RNA synthesis at the time of transcription is called an anticoding or antisense strand while the other strand is called coding or sense strand as its base sequence is the same as that of newly synthesized mRNA.

Therefore, the correct answer is option C.

Note:
While DNA and RNA polymerases both catalyze nucleotide polymerization reactions, there are two major differences in their activity. Unlike DNA polymerases, the RNAP enzymes do not need a primer to begin the polymerization reaction. They are also capable of beginning the reaction from the middle of a DNA strand and reading ‘STOP’ signals that cause the enzyme complex to dissociate from the template.
