Verified step by step guidance

Understand the role of RNA polymerase in gene expression. RNA polymerase is an enzyme responsible for synthesizing RNA from a DNA template during transcription.

Recognize that RNA polymerase catalyzes the formation of phosphodiester bonds between ribonucleotides, linking them together to form a strand of RNA.

Identify the process of transcription, where RNA polymerase binds to the promoter region of a gene and unwinds the DNA strands to access the template strand.

Learn how RNA polymerase reads the DNA template strand and adds complementary ribonucleotides to the growing RNA chain, ensuring the sequence matches the DNA template.

Note that RNA polymerase continues elongating the RNA strand until it reaches a termination signal, at which point the newly synthesized RNA molecule is released.
