Textbook Question
Chapter 19, Problem 27P

a. | What aspect of the screen imposed this limitation? |
b. | How could you determine if any of the mutations identified are in genes required in males? |
c. | Why was the Balancer chromosome needed in the screen? |

In this module, you have learned about the use of balancer chromosomes (such as TM2 and TM6C in the below crossing scheme) for isolating Drosophila mutants during EMS mutagenesis. Please inspect the following crossing scheme and choose which of the following statements is correct.
A.
TM6C is preferable over TM2 when performing mutagenesis
B.
EMS induces chromosomal inversion
C.
A balancer chromosome helps to isolate on which chromosome the mutant is located
D.
Following the above crossing scheme all flies with no TM2 or TM6C markers are mutants
Drosophila females homozygous for loss-of-functionmutations in the gene aubergine are sterile. RNA-Seqexperiments show that in the ovaries of these females,the levels of RNAs for many kinds of transposable elements are more than 10× higher than in wild-type ovaries. The aubergine gene encodes a Piwi-family protein.a. Why do you think these females are sterile?b. Piwi proteins interact with piRNAs that are transcribed from piRNA gene clusters. Given that thelevels of many kinds of TEs are elevated in mutantovaries, what kinds of DNA sequences do youthink are located in these clusters?c. Many investigators think of piRNAs as a kind ofdefensive mechanism that protects organisms fromthe effects of new transposable elements that mightbe introduced into genomes, for example fromother species.

Mutations in the HPRT1 gene in humans result in atleast two clinical syndromes. Consult OMIM (www.omim.org) by querying HPRT1; you will only needto look briefly at the top three hits (files #300322,300323, and 308000).a. What is the full name of the HPRT1 enzyme?b. On which chromosome is the HPRT1 gene located?c. Mutations in HPRT1 are associated with two different syndromes. What are these syndromes? Foreach, answer the following questions: (i) What arethe symptoms associated with the syndrome? (ii) Isthe mutant allele that causes the syndrome dominant, recessive, codominant, or incompletely dominant with respect to the normal allele, or do specialconditions apply? (iii) Is the syndrome associatedwith a loss-of-function or a gain-of-function disease allele? (iv) Does the syndrome display allelicheterogeneity? (v) Does the syndrome display locus heterogeneity? (Note: You do not need to understand everything in the OMIM entries to answerthese questions.)

- a. Describe two ways you could potentially make atransgene that would inhibit the function of a specific gene in a transgenic organism. (Hint: For oneof these techniques, recall the discussion of RNAinterference in Chapter 17.)b. Discuss how you could use either of these methodsto construct a mouse model for a recessive humangenetic condition associated with a loss of function, such as cystic fibrosis.arrow_forwardNot all inherited traits are determined by nuclear genes (i.e., genes located in the cell nucleus) that are expressed during the life of an individual. In particular, maternal effect genes and mitochondrial DNA are notable exceptions. With these ideas in mind, let’s consider the cloning of a sheep (e.g., Dolly). A. With regard to maternal effect genes, is the phenotype of such a cloned animal determined by the animal that donated the enucleatedegg or by the animal that donated the somatic cell nucleus? Explain.arrow_forwardYou are interested in studying resistance to heavy metals and have selected the yeast Saccharomyces cerevisea to conduct your studies. You have recovered a deletion mutant that does not tolerate high concentrations of zinc (grows poorly in zinc containing media ) and have designated the mutant pgz-1 (for poor growth in zinc ). (a) What is the advantage to the type of mutant used in this work? What class of mutagen was likely use to generate pgz-1? ( b) Do you expect the PGZ gene to be expressed in your mutant?

- Suppose a researcher has three different Drosophila strains that have mutations in the bicoid gene called bicoid-A, bicoid-B, and bicoid-C; the wild type is designated bicoid +. To study these mutations, phenotypically normal female flies that are homozygous for the given bicoid mutation were obtained, and their oocytes were analyzed using a Northern blot to determine the size and/or amount of the bicoid mRNA and in situ hybridization to determine the bicoid mRNA location within the oocyte. A wild-type strain was also analyzed as a control. In both cases, the probe was complementary to the bicoid mRNA and the results are shown below. (Anterior is on the left; posterior is on the right.) Northern blot 1 2 - 3 4 In situ hybridization Wild type Lane 1. Wild type (bicoid*) Lane 2. bicoid-A Lane 3. bicoid-B Lane 4. bicoid-C bicoid-B bicoid-A bicoid-C Which mutation is likely to cause the embryo to develop two "anterior" ends? bicoid-B Obicoid-A bicoid-Carrow_forwardThe restriction digests of the cloned Drosophila gene can provide direct visible evidence of a mutation, as these samples come from a clone of the gene. In order to similarly detect a mutation in the copy of the endogenous gene within the Drosophila genome, a mechanism for specifically detecting restriction fragments from that gene among the complex set of fragments generated in a restriction digest of the entire Drosophila genome. Remember that the Drosophila melanogaster genome consists of ~123,000 kb. For a 10.2 kb Drosophila gene, what fraction of the genome does this gene constitute?arrow_forwardA normal appearing female infant was identified with a positive newborn screen, linked to chromosome 12. Few years ago, her older sibling had developed profound hypoglycemia, liver failure leading to coma, and subsequent irreparable brain damage, following a viral illness. The sibling was subsequently shown by clinical testing to have the same disorder that this female infant is screened positive for. a. What is the most likely diagnosis? b. What biomarkers would confirm this on the newborn screening process? Describe the mechanism that causes this metabolic defect.arrow_forward
- In the module, you have learned about P-element mediated transgenesis in Drosophila and the concept of using transgenes to rescue mutant phenotypes. In the figure below, you will see a wild type fly with its natural eye colour and three mutants with their eye colours changed to vermillion, white and rosy, respectively. A schematic of P-element mediated transgenesis (as shown in the lectures) is also included in the figure. Please inspect the schematic carefully and choose which of the following statements is true: I. Injection of the white experimental transgene into the vermillion mutant embryo will not change the vermillion mutant phenotype II. Injection of the white experimental transgene in the rosy mutant embryo will change rosy eye colour to red (wild type) III. Injection of the white experimental transgene in the white mutant embryo will not change the white mutant phenotype IV. Injection of the white experimental transgene in the rosy mutant…arrow_forwardAfter Drosophila DNA has been treated with a restrictionenzyme, the fragments are inserted into plasmids and selected as clones in E. coli.

Allele “Xr” represents the mutated version of the Xist promoter, and “XR” represents the normal version of the Xist promoter. How will this mutation affect the process of X inactivation?A. "X inactivation will still be random with both mutant and normal X chromosomes being randomly inactivated" B. "The chromosome with the mutant Xist promoter will always be active" C. "The chromosome with the mutant Xist promoter will always be inactivated" D. "The normal X chromosome (no mutation in Xist) will always be active" E.

Would the cloned animal inherit extranuclear traits from theanimal that donated the egg or from the animal that donated thesomatic cell? Explain.C. In what ways would you expect this cloned animal to be similarto or different from the animal that donated the somatic cell?
