How the activity of a transcription factor can determine the cell type. Introduction: The transcription factors are the major proteins that control the expression of a gene expression. It either stimulates or represses the expression of genes based on its activity. It plays an important role in many cellular processes such as cell division, cell growth, cell migration, and so on.

Expert Solution & Answer

Explanation of Solution

The transcription factors play a central role in regulating the gene expression by binding to the regulatory sequences in the DNA. When it binds to the gene sequence, it forms a complex where the RNA polymerase binds and carries out the transcription process for the formation of mRNA. A single type of transcription factor can bind to a specific sequence of DNA. This specific sequence can be found in many different genes. Thus, a single type of transcription factor can affect the expression of many genes. Some types of transcription factors affect the expression of other transcription factors that generate a cascade and amplify the further effect. Thus, some transcription factors serve as master regulators that can cause the cell to produce or repress many proteins that make a cell to undergo new fate. Hence, the transcription factors can establish the activity of the cell.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
