Explain the process of rna transcription in detail
Answers
Answer:
The RNA transcription process occurs in three stages: initiation, chain elongation, and termination.
The first stage occurs when the RNA Polymerase-Promoter Complex binds to the promoter gene in the DNA. This also allows for the finding of the start sequence for the RNA polymerase. The promoter enzyme will not work unless the sigma protein is present (shown in blue in graphic). Specific sequences on the non coding strand of DNA are recognized as the signal to start the unwinding process.
The recognition sequences are as follows:

Once the process has been initiated, then the RNA polymerase elongation enzyme takes over and is described in the next panel.

Explanation:
Transcription, the synthesis of RNA from DNA. Genetic information flows from DNA into protein, the substance that gives an organism its form. This flow of information occurs through the sequential processes of transcription (DNA to RNA) and translation (RNA to protein)
