The transcription of a gene called YFG (your favoritegene) is activated when three transcription factors (TFA,TFB, TFC) interact to recruit the co-activator CRX. TFA,TFB, TFC, and CRX and their respective binding sitesconstitute an enhanceosome located 10 kb from the transcription start site. Draw a diagram showing how youthink the enhanceosome functions to recruit RNA polymerase to the promoter of YFG.
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
The transcription of a gene called YFG (your favorite
gene) is activated when three transcription factors (TFA,
TFB, TFC) interact to recruit the co-activator CRX. TFA,
TFB, TFC, and CRX and their respective binding sites
constitute an enhanceosome located 10 kb from the transcription start site. Draw a diagram showing how you
think the enhanceosome functions to recruit RNA polymerase to the promoter of YFG.
