Within a cell, the amount of protein made with a given mrna depends partly on, a, the transcription factors, b, the rate of mrna degradation, c, the degree of dna methylation, or d, the number of introns in the mrna.
00:19
So protein synthesis is done by translation.
00:22
So this happens in ribosomes, mrna goes in, it's red, polypeptide is made.
00:28
Why do i point that out? well, a and c don't affect translation.
00:33
They affect the chance of getting the mrna in the first place.
00:37
Transcription factors decide whether or not it is actually transcribed.
00:41
So does dna methylation.
00:43
If the promoter is methylated, then you're probably not going to get transcription.
00:50
So these can't be the answer because we already have the mrna molecule.
00:54
So it's been transcribed...
