(a)
To predict: The way in which the noncyclic electron flow was affected in the hcef mutant plants as compared to normal Arabidopsis plants.
Introduction: A mutant of the Arabidopsis thaliana plant has been isolated by Livingston et al. This mutant plant, called the hcef plant because it has a higher flow of electrons in the cyclic process around the photosystem I.
(b)
To predict: The effect of mutation on the light-driven proton flux across the thylakoid membrane.
Introduction: A mutant of the Arabidopsis thaliana plant has been isolated by Livingston et al. This mutant plant, called the hcef plant because it has a higher flow of electrons in the cyclic process around the photosystem I.
(c)
To predict: The effect of the mutation on the activity of PSII.
Introduction: A mutant of the Arabidopsis thaliana plant has been isolated by Livingston et al. This mutant plant, called the hcef plant because it has a higher flow of electrons in the cyclic process around the photosystem I.
(d)
To predict: The enzyme which is defective in the mutant hcef plant that is causing a large increase in the level of fructose-1,6-bisphosphate in the stroma of the mutant plant.
Introduction: A mutant of the Arabidopsis thaliana plant has been isolated by Livingston et al. This mutant plant, called the hcef plant because it has a higher flow of electrons in the cyclic process around the photosystem I.
(e)
To predict: The way in which the starch synthesis in the stroma is affected in mutant hcef plants as compared to normal Arabidopsis plants.
Introduction: A mutant of the Arabidopsis thaliana plant has been isolated by Livingston et al. This mutant plant, called the hcef plant because it has a higher flow of electrons in the cyclic process around the photosystem I.

- Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forwardMolecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed and translated, it produced a different protein than it produced in the eukaryotic cell. What is the most likely explanation?arrow_forward
