ranscription / DNA transcription. 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.
Transcription is the<span> process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes.
