Question
Chapter 15.4, Problem 1C
Summary Introduction
To predict: The function of the gene in C. elegans that resulted in the inability of worm to touch when it is exposed to an RNAi molecule homologous to a non-protein-coding RNA gene.
Concept introduction: MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are non-coding RNA sequences that regulate the gene function and expression. They are approximately 20-30

Name and describe three ways in which gene expressioncan be influenced after mRNA is processed and leaves thenucleus.
Which of the following correctly explains how gene expression can change in a differentiating cell in an animal embryo?A. DNA methylation triggered by apoptosis leads to suppression of some genes and expression of others.B. Presence of germ layers trigger hormonal release from endocrine glands, signaling to certain cells to express genes.C. Cell signals through plasmodesmata allow coordination of cellular activities and cell differentiation.D. Cues from the cytoplasm and from surrounding cells can induce changes in gene expression.
Suppose that Drosophila has 3 thoracic hox genes (PS3 - PS5) and 10 abdominal hox genes (PS6 - PS15) corresponding to the three thoracic and 10 abdominal body segments. What would happen to the development of the fly if you inactivated PS6 and PS7?

- Signal transduction pathways are important mechanisms for cell-to-cell communication in multicellular organisms. How do the target cells typically respond when they receive signals from neighboring cells during very early stages of embryo development? A. The target cells move to one of the poles to establish the anterior-posterior body axis. B. The target cells undergo changes in gene expression, sending them down a specific developmental path. C. The target cells stop dividing so the neighboring cells have time to get to the same stage of development. D. The target cells activate a collection of miRNAs to accelerate transcription and cell division.arrow_forwardExpression of a homeotic gene in the wrong tissue in Drosophila results in the development of an inappropriate body part from that tissue.

- A C. elegans (nematode) gene called par-1 helps todetermine the AP axis of the animal early in development. Scientists determined that par-1 is pleiotropic—it also has a later function in forming the vulva of theadult animal. How could researchers circumvent thelethality of par-1− mutants to observe the later function of the par-1 gene? (Hint: C. elegans larvae caneat bacteria expressing RNAi for any gene.)arrow_forwardSuppose you want to determine whether a particulargene X is important for specification of the pharynx,but mutations in this same gene disrupt embryonicdevelopment well before pharyngeal structures appear.How could you use myo-2::GFP, the myo-2 promoter,the DNA sequence of gene X, and your knowledge ofRNA interference (RNAi) to generate worms that lackgene X expression in the pharynx but express gene Xin all other tissues in which it is expressed in wildtype C. elegans?arrow_forwardWhat is the function of the Pax 6 gene in the mouse eye reference to HOX gene?arrow_forward

D = dorsal; V = ventral. a) a mutation which results in the deletion of the cytoplasmic domain of the Cookie protein. b) A mutation which results in a constitutively active Bombe protein, i.e. the Bombe protein is always in an activated state. c) A mutation which causes the Pickle protein to be retained in the cytoplasm of the embryo.arrow_forwardYou inject bicoid MRNA into the posterior end of a fertilized fruit fly egg just prior to the first cleavage. How will the experiment affect Hox gene expression in this fly? How will it affect the fly embryo's anatomy? Explain your answer, demonstrating your understanding of the role bicoid and Hox genes play in development.arrow_forwardAbsence of bicoid mRNA from a Drosophila egg leads to theabsence of anterior larval body parts and mirror-imageduplication of posterior parts.
