To answer this question, let us understand that what is transcription.
00:08
So, transcription is a process of formation of mrna, that is messenger rna, from dna.
00:25
Transcription can be seen in both prokaryotes and eukaryotes.
00:34
This diagram given here depicts the transcription in prokaryotes.
00:38
Carriers.
00:42
So transcription is done in three steps.
00:44
First is called as the initiation.
00:47
Second step is elongation and third step is termination.
00:51
So let us first see that what is the process of initiation.
00:55
The transcription is initiated by the enzyme rna polymerase, holoenzyme from a specific point called as promoter sequence.
01:04
So here we can see the promoter sequence.
01:06
Promoter sequence is any sequence which initiates the process.
01:15
So, from this promoter sequence, the rna polymerase initiates the process of transcription...
