The entire genome of the yeast Saccharomyces cerevisiae has been sequenced. This sequencing has led to the identification of all the open reading frames (ORFs, gene-size sequences with appropriate translational initiation and termination signals) in the genome. Some of these ORFs are previously known genes with established functions; however, the remainder are unassigned reading frames (URFs). To deduce the possible functions of the URFs, they are being systematically, one at a time, converted into null alleles by in vitro knockout techniques. The results are as follows:15 percent are lethal when knocked out.25 percent show some mutant phenotype (altered morphology, altered nutrition, and so forth).60 percent show no detectable mutant phenotype at all and resemble wild type.Explain the possible molecular-genetic basis of these three mutant categories, inventing examples where possible.
There 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)
Define FOUR (4) types of point mutations within coding sequences

- Researchers 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_forwardDescribe the similarities and differences between prokaryotic and eukaryotic promoter sequences.arrow_forward. Let’s say that you have incredible skill and can isolate the white and red patches of tissue from the Drosophila eyes shown in Figure 12-24 in order to isolate mRNA from each tissue preparation. Using your knowledge of DNA techniques from Chapter 10, design an experiment that would allow you to determine whether RNA is transcribed from the white gene in the red tissue or the whitetissue or both. If you need it, you have access to radioactive white-gene DNAarrow_forward
