Question

What is the main function of RNA polymerase?

Answer 1

Transcription:

1. Transcription is one of the first processes in gene expression.
2. The genetic information flows from DNA to protein and this flow of information takes place in a sequential process of transcription and translation.
3. Only one strand of DNA is copied during the process of transcription known as the template strand and the RNA formed is called the mRNA.
4. The main motive of transcription is to make a copy of RNA from the DNA sequence. The RNA transcript carries the information used to encode a protein.

Main function of RNA polymerase:

1. The RNA polymerase is the main enzyme involved in transcription.
2. It uses single-strand DNA to synthesize a complementary RNA strand.
3. RNA is further used to synthesize proteins in the process of translation.
