Mel and Jermaine learned from their science teacher that some of the trees in the small grove of orange trees on their
school's campus might be suffering from citrus canker. This
bacterial disease can affect any type of citrus tree and causes
brown spots on the leaves and fruit of an infected tree. As the
disease progresses, it can lead to loss of leaves, shoot
dieback, and early fruit drop. Jermaine and Mel work with their
science teacher to devise a plan to investigate and stop the
spread of this disease.
List two types of technology the students will need to conduct
their research and how they will use those tools. Explain the
benefits and limitations of these two pieces of technology.
Give an example of a model Mel and Jermaine could create to
help in their investigation and explain a limitation to that type of
model.

Which of the following statements regarding anfinsen's denaturing experiments with ribonuclease a (rnase a) are valid? exposing the denatured protein to air oxidation and then dialysis to remove urea restored the protein to its original functionality. removing urea by dialysis and then allowing air oxidation of the denatured protein restored the protein to its original functionality. denaturing the protein with both urea and β-mercaptoethanol yielded an inactive protein. anfinsen concluded that protein folding is determined by its primary sequence.

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
