Answer:
Transcription
Explanation:
DNA is the stored form of genetic material in living cells. It contains all genetic information that the cell needs to function. However, to be effective, this information needs to be expressed. The expression of a gene involves how the information encoded by that gene is used to synthesize proteins. Gene expression involves two major steps viz: transcription and translation.
Transcription is the first process of gene expression that involves the copying of the information in a DNA into a RNA molecule. It is carried out by an enzyme called RNA polymerase, which attaches to a region on the DNA and begins to add complementary nuceleotide bases to the growing RNA strand.
