What is transcript factor? How does transcript factor regulate gene expression?
Transcript factors are proteins which controls the transcription rate of the genetic data form DNA to mRNA as it binds to particular sequence of DNA. These proteins are responsible for the conversion & transcribing of DNA into mRNA. RNA polymerase is not a transcription factor.
The rranscrtransc factor binds to the regulatory sequence like enhancer sequence & they have the ability to trigger or suppress the transcription of the particular gene.

Explain how DNA methylation could be used to regulate gene expression in a tissue-specific way. When and where would de novo methylation occur, and when would demethylaiton occur? What would occur in the cells that give rise to eggs and sperm (germ-line cells)
What control elements regulate expression of the mPGES-1 gene? The promoter of a gene includes the DNA immediately upstream of the transcription start site, but expression of the gene can also be affected by control elements. These can be thousands of base pairs upstream of the promoter, grouped in an enhancer. Because the distance and spacing of these control elements make them difficult to identify, scientists begin by deleting sections of DNA that contain possible control elements and measuring the...
In eukaryotic cells, there are specific transcription factors (activators) that regulate gene expression. Describe the organization of eukaryotic genes (i.e. promoters/enhancers) and how transcription factors are able to control gene expression and enzyme activity. a) Throughout the course we discussed the enzyme lactase and how it is differently regulated (and therefore expressed) in different human populations. Describe how this gene is differently expressed in different populations and when this/these change(s) are predicted to have taken place. b) Differential gene expression...
