Concept explainers
(a)
To determine: The way by which deletion within the GAL4 gene would affect transcription of the yeast GAL1 gene in the presence of galactose.
Introduction: Transcription is the process of formation of RNA (ribonucleic acid) from the complementary DNA (deoxyribonucleic acid). GAL genes are required for the proper growth of yeast in galactose medium. The regulation of GAL genes is regulated by the products of GAL4, GAL8, and GAL3 genes. Mutation in these regions may disrupt the process of transcription in yeast.
(b)
To determine: The way by which deletion within the entire GAL3 gene would affect transcription of the yeast GAL1 gene in the presence of galactose.
Introduction: As mentioned in the concept introduction part a.
(c)
To determine: The way by which deletion of a mutation within the GAL80 gene that blocks the ability of Gal80 protein to interact with Gal3p would affect transcription of the yeast GAL1 gene in the presence of galactose.
Introduction: As mentioned in the concept introduction part a.
(d)
To determine: The way by which deletion of one of the four UASG elements upstream from the GAL1 gene would affect transcription of the yeast GAL1 gene in the presence of galactose.
Introduction: As mentioned in the concept introduction part a.
(e)
To determine: The way by which a point mutation in the GAL1 core promoter that alters the sequence of the TATA box would affect transcription of the yeast GAL1 gene in the presence of galactose.
Introduction: As mentioned in the concept introduction part a.

- Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?arrow_forwardSelection of Traits What adaptations do scavengers have for locating and feeding on prey? What adaptations do predators have for capturing and consuming prey?arrow_forwardCompetition Between Species What natural processes limit populations from growing too large? What are some resources organisms can compete over in their natural habitat?arrow_forward
- Species Interactions Explain how predators, prey and scavengers interact. Explain whether predators and scavengers are necessary or beneficial for an ecosystem.arrow_forwardmagine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters? Which of these are examples of active transport?arrow_forward

What are chemotactic factors? How do they affect inflammation process?arrow_forwardCompare and contrast neutrophils and macrophages. Describe two ways they are different and two ways they are similar.arrow_forward
