WebMar 22, 2024 · The configuration of the DNA molecule is highly stable, allowing it to act as a template for the replication of new DNA molecules, as well as for the production (transcription) of the related RNA (ribonucleic acid) molecule.A segment of DNA that codes for the cell’s synthesis of a specific protein is called a gene.. DNA replicates by … WebMar 5, 2024 · Steps of Transcription. Transcription takes place in three steps: initiation, elongation, and termination. The steps are illustrated in Figure below.. Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter.This signals the DNA to unwind so the enzyme can ‘‘read’’ …
