Hello everyone.
00:01
So the answer to this question is that if we just check that the two macro molecules, the two macro molecules to which the sigma factor bind, the sigma factor bind are like the first is the rna polymer is core enzyme.
00:32
Rna polymerase core enzyme.
00:41
Okay? and the other one is the dna stretch that has to be transcribed.
00:49
The dna stretch that has to be transcribed.
01:00
Okay.
01:04
Now if we check over here, like a main function of the sigma function.
01:09
Factor, main function of sigma factor.
01:18
That is basically that is the recognition of the promoter sequence.
01:27
Recognition of promoter sequence.
01:36
Okay? that initiates the transcription but due to mutation the sigma factor is not able to recognize the promoter.
01:43
Thus, the initiation will not occur because this promoter initiates transcription.
01:54
Okay? transcription...
