Textbook Question

Chapter 18, Problem 1P

Explain why many developmental genes encode either transcription factors or signaling molecules.

Expert Solution & Answer

Summary Introduction

To analyze:

To describe the reason for the fact that a number of developmental genes are responsible to encode for the transcription factors and signaling molecule.

Introduction:

The genes that direct the development and fate of an organism are known as developmental genes. Developmental genes code for the indicating molecule or transcription factor. The transcription of genetic information is controlled by the transcription factor.

Explanation of Solution

Transcription factor can initiate or stop the transcription of a particular gene in response to stimuli. This activity permits the variation in all morphology required for cellular differentiation. In this way, the transcription factor plays an important role in multicellular organism development. Bicoid is a transcription factor that is important for the development of the head region in drosophila.

The maturation of the cell at a functional level is known as differentiation. In the developing embryo, differentiation of various types of cell is directed by the signaling molecule; thus both, signaling molecule and transcription, are crucial for the proper development of the organism.

Conclusion

Signaling molecule and transcription are crucial for the proper development of the organism.

Expression of a homeotic gene in the wrong tissue in Drosophila results in the development of an inappropriate body part from that tissue. Explain why this happens and how it shows that homeotic genes are positive regulators of developmental pathways.

Draw a diagram to illustrate how a concentration gradient of a transcription factor along the anterior-posterior axis of a Drosophila embryo can create a region in the middle in which transcription of a target gene takes place without being transcribed in either the anterior or posterior region.
