Textbook Question
Chapter 20, Problem 32ESP
In humans, congenital heart disease is a common birth defect that affects approximately 1 out of 125 live births. Using reverse transcription PCR (RT-PCR) Samir Zaidi and colleagues [(2013) Nature 498:220.223] determined that approximately 10 percent of the cases resulted from point mutations, often involving histone function. To capture products of gene expression in developing hearts, they used oligo(dT) in their reverse transcription protocol.
- (a) How would such a high %T in a primer influence annealing temperature?
- (b) Compared with oligo(dT) primers, a pool of random sequence primers requires a trickier assessment of annealing temperature. Why?
- (c) If one were interested in comparing the quantitative distribution of gene expression in say, the right and left side of a developing heart, how might one proceed using RT-PCR?

The accompanying photo shows a sequencing gel from the original study that first sequenced the cystic fibrosis gene (J. R. Riordan et al. 1989. Science 245:1066–1073). From the photo, determine the sequence of the normal copy of the gene and the sequence of the mutated copy of the gene. Identify the location of the mutation that causes cystic fibrosis. (Hint: The CF mutation is a 3-bp deletion.)
Mutations in the CFTR gene result in cystic fibrosis in humans, a conditions in which abnormal secretions are present in the lungs, pancreas, and sweat glands. The gene was mapped to a 500-kb region on chromosome 7 containing 3 candidate genes.
a)Using your knowledge of the disease symptoms, how would you distinguish between the candidate genes to decide which is most likely to encode the CFTR gene?
b)How would you prove that your chosen candidate is the CFTR gene?
Most organisms display a circadian rhythm, a cycling of biological processes that is roughly synchronized with day length. In Drosophila, pupae eclose (emerge as adults after metamorphosis) at dawn.
a)Using this knowledge how would screen for Drosophila mutants that have an impaired circadian rhythm?
b)In each case, how would you clone the genes you identified by mutation?

- Genome annotation refers to ... 1.) lining up overlapping regions in short shotgun sequencing reads to assemble larger contiguous DNA sequences (contigs/scaffolds). 2.) using long-read sequencing platforms (such as PacBio or Oxford Nanopore) to gather information about the epigenetic status of each region of a sequenced genome. 3.) the process of predicting which parts of a genome sequence code for functional products (such as protein-coding genes), what those products do, and assigning them names. 4.) sequencing messengeRNA measure the relative expression levels of genes in one or more tissue samples.arrow_forwardBy whole-exome sequencing, you have identified an early termination mutation in KLHL4 in a human patient with an undiagnosed blood vessel anomaly. There is almost nothing known about the function of this gene, and no existing animal models! To begin to understand its function, you decide to use the zebrafish model. You first want to know where in the embryo this gene is expressed. Which technique would you use to identify the cell type that expresses klhl4 mRNA in zebrafish embryos? You find that this gene is expressed in endothelial cells, which line blood vessels. Intrigued by this finding, you next decide to disrupt the gene in zebrafish using CRISPR/Cas9.

What would be the effects of EMS in a strain of Drosophila lacking functional mismatch repair systems?arrow_forwardAlthough several different mammalian species have been cloned, the efficiency of this process is extremely low. Often tens or even hundreds of oocytes must be implanted with donor nuclei to obtain one healthy live birth. Many researchers believe the difficulties with cloning reside in the epigenetic modifications, such as DNA and histone methylation, that occur within various cells during an individual’s life. How do you suspect such modifications might affect the success of an experimentarrow_forwardThere is a hypothetical gene related to the nervous system of Drosophila. Describe all the methods, steps, and key substances you need to obtain to use the following techniques in experimental design to study the gene: - In situ hybridization (to find the mRNA) - Immunohistochemistry (to find the protein) - CRISPR-Cas9 (for loss of function) - Expression vector (for gain of function)arrow_forward
- Retinoblastoma is an extremely rare cancer of the retina in the eye. The disease mainly affects children up to the age of 5 years because it can only occur while the nerve precursor cells are still dividing. In its nonhereditary form, a tumor usually occurs in only one eye; in its hereditary form, multiple tumors develop in both eyes.To explore the basis for these differences, a cDNA clone of the Rb gene was used to probe the structure of the gene in cells from normal individuals and from individuals with nonhereditary or hereditary retinoblastoma. As shown in the figure Part A, normal individuals have four restriction fragments (A, B, C, and D) that hybridize to the Rb cDNA probe, indicating that each restriction fragment encodes at least one Rb exon. Samples from fibroblasts and tumor cells of affected persons show some differences in the patterns of hybridization, with some bands missing entirely and some bands present at half intensity. The order of the restriction fragments in the…arrow_forwardYou isolate genomic DNA from brain cells and heart cells and use PCR to amplify the promoter region of gene A, known to be methylated under certain circumstances. To determine which cell type has methylation in this region, you treat the DNA with sodium bisulfite, sequence the regions from both brain and heart cells, and compare to the untreated sequence, as shown below.

In Streptococcus pneumoniae (which causes many cases of pneumonia, inner-ear infections, and meningitis), the ability to carry out transformation requires from 105 to 124 genes, collectively termed the com regulon. The com regulon is activated in response to a protein called competence-stimulating peptide (CSP), which is produced by the bacteria and exported into the surrounding medium. When enough CSP accumulates, it attaches to a receptor on the bacterial cell membrane, which then activates a regulator protein that stimulates the transcription of genes within the com regulon and sets in motion a series of reactions that ultimately result in transformation. Does the com regulon in Streptococcus pneumoniae exhibit positive or negative control? Explain your answerarrow_forward
- The genome of Drosophila melanogaster, a fruit fly, was sequenced in 2000. However, this “completed” sequence did not include most heterochromatin regions. The heterochromatin was not sequenced until 2007 (R. A. Hoskins et al. 2007. Science 316:1625–1628). Most completed genome sequences do not include heterochromatin. Why is heterochromatin usually not sequenced in genome-sequencing projects?arrow_forwardResearchers have identified a gene (FR) responsible for watermelon resistance to infection by Dacus curcurbitae (a close relative of Drosophila melanogaster). They isolate RNA from resistant (FR+) and sensitive (fr-) watermelons and use a probe that will recognize both FR+ and fr- transcripts. They also isolate protein from resistant and sensitive watermelons and perform a Western blot using an antibody that can recognize the fr- and FR+ protein. Describe the results illustrated below and give a plausible molecular explanation for these observations.arrow_forwardTransformation is a process in which bacteria take up new DNA released by dead cells and integrate it into their own genomes.
