By definition, temperature-sensitive (ts) Sec mutants accumulate a full-length GFP-fusion secretory protein at an intermediate location in the secretory pathway when cells are incubated at the non-permissive temperature. The entire GFP-fusion protein must be synthesized in order for you to visualize it. Any mutation that prevents synthesis of the entire protein will not be detected in a Sec mutant screen because there is nothing to see. With this in mind, which of the following three P54SRP ts mutants would generate a Class A Sec phenotype at the non-permissive temperature? A. ts P54SRP does not bind to the N-terminal signal sequence at the non-permissive temperature.
B. ts P54SRP cannot hydrolyze GTP at the non-permissive temperature.
C. ts P54SRP cannot bind to the SRP receptor α subunit at the non-permissive temperature.
D. Both (a) and (b) would generate a Sec A phenotype.
E. Both (a) and (c) would generate a Sec A phenotype.
F. Both (b) and (c) would generate a Sec A phenotype.

How do diseases caused by bacteria and diseases caused by viruses react to antibiotics?

Pink fur (p) is dominant to purple fur (p) in hamsters. two heterozygous pink hamsters are crossed. what is the probability that these two parents will have an offspring with purple fur? 2/4, 1/2 or 50% 1/4 or 25% 3/4 or 75% 4/4 or 100% there is no chance for this type of offspring

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
