Transcription is the process in which an RNA copy of the DNA sequence and coding the gene is produced with the help of an enzyme called:

Explanation

RNA polymerase is the main transcription enzyme. RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, which are the building blocks of DNA. The enzymes play an essential role in DNA replication, usually working in pairs to produce two matching DNA stranges from a single DNA molecule. There are no enzymes known as DNA or RNA transcriptase. However, we have Reverse Transcriptase (RT) which is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed as 'reverse transcription'.
