Describe the stages of transcription
WebInitiation: The first stage of transcription when RNA polymerase binds to a DNA sequence. Elongation: The addition of nucleotides to the 3′-end of a growing RNA chain during transcription. Termination: The last stage of transcription when the production of an RNA transcript ends. WebJun 8, 2024 · Key Points. Eukaryotic transcription is carried out in the nucleus of the cell and proceeds in three sequential stages: initiation, elongation, and termination. Eukaryotes require transcription factors to first bind to the promoter region and then help recruit the …

In the initial stages of assessment, the primary health setting can provide a safe space in which the individual … WebTranscription is the process by which DNA is copied into mRNA. This process begins when an enzyme called RNA polymerase binds to the DNA strand at an area known as the promoter region. The RNA polymerase then separates the two strands of the DNA and begins to transcribe the genetic information contained within the DNA into mRNA …
WebNov 21, 2024 · It occurs in two steps: transcription and translation. Transcription is the first step of protein synthesis, during which the DNA sequence of a gene is copied into RNA. Translation is the second step of protein synthesis, during which the RNA sequence is used to produce a protein. WebTranscription and Translation.
