Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). ... The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.

What does messenger RNA do during transcription?
Messenger RNA Carries the Instructions for Making Proteins
The process of making mRNA from DNA is called transcription, and it occurs in the nucleus. The mRNA directs the synthesis of proteins, which occurs in the cytoplasm.
What is the process of transcribing DNA to messenger RNA?
During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1).
What RNA does during transcription?
mRNA (messenger RNA): Produced during transcription. Carries the genetic instructions of a gene from the nucleus to the ribosome in the cytoplasm. rRNA (ribosomal RNA): Together with proteins, composes the ribosome, the organelles that are the site of protein synthesis.
Does transcription occur in RNA?
Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.
