WebbThe steps involved in transcription are as follows: Initiation: RNA polymerase, the enzyme responsible for transcription, binds to the promoter region of DNA, which signals the start of a gene. Elongation: RNA polymerase moves along the DNA strand, unwinding it and adding complementary RNA nucleotides to the growing RNA strand. Webb26 juli 2024 · 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 appropriate polymerase.

WebbInitiation is the first step of transcription. The RNA polymerase binds to the promoter which is a region of DNA. The promoter is responsible for telling the RNA polymerase where to begin transcribing on the strand. Each gene in prokaryotes and eukaryotes has a promoter that contains DNA sequences that allow RNA polymerase to attach. WebbInitiation It is the primary stage of transcription. Here, the RNA polymerase binds to the specific sequence or promoter region of the coding DNA strand. The majority of bacteria have two consensus sequences (-10 and -35) in the promoter region.

Webb21 nov. 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.
