Question
Chapter 18.6, Problem 2CC
Summary Introduction
To explain:
Why flies and mice are so different, even though the DNA sequences called home boxes are common.
Introduction:
The genes that regulate the structural development in many plants, echinoderms, insects and mammals are known as homeotic genes. The regulation of homeotic genes is done through transcription factors programming and these transcriptional factors affect the homeotic genes via genetic regulatory pathways.
Mutations in these genes result in displacement of the body parts. For example, antennae displaced in the posterior part of the fly instead the head portion. The homeotic genes are mainly of two types: ParaHox and Hox which play important role in segmentation.

Students have asked these similar questions
You have discovered a gene in mice that is similar to a gene in yeast. How might you determine whether this gene is essential for development in mice
The MyoD gene in mammals plays a role in skeletal muscle-cell differentiation, whereas the Hox genes are homeotic genes that play a role in the differentiation of particular regions of the body. Explain how the functions of these genes are similar and different.
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.

- Exposing C. elegans to an RNAi molecule homologous to a non-protein-coding RNA gene resulted in the worms’ inability to respond to touch. What predictions could you make about the function of that gene in development?arrow_forwardAnother way to study the role of proteins (e.g., transcription factors) that function in development is to microinject the mRNA that encodes a protein, or the purified protein itself, into an oocyte or embryo, and then determine how this affects the subsequent development of the embryo, larva, and adult. For example, if Bicoid protein is injected into the posterior region of an oocyte, the resulting embryo will develop into a larva that has anterior structures at both ends. Based on your understanding of the function of each developmental gene, what would be the predicted phenotype if the following proteins or mRNAs were injected into normal oocytes? A.
