Detailed explanation-1: -The Transcription Process. The process of transcription begins when an enzyme called RNA polymerase (RNA pol) attaches to the template DNA strand and begins to catalyze production of complementary RNA.

Detailed explanation-2: -Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.

Detailed explanation-3: -In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.
