Textbook Question
Chapter 1, Problem 13PIAT
Quantitative Researchers hypothesized that leaf mimicry by B. trifoliolata provides protection from plant-eating animals (herbivores). The results of a study of 45 individual vines are shown in the following graph. Light conditions were very similar in all cases. Researchers compared the level of leaf damage by plant eaters (herbivory index) in vines climbing leafy host trees, vines creeping on the ground with no support, and vines climbing on bare tree trunks. Use the P values provided to determine if the differences are significant or not (*** means P < 0.001, see BioSkills 3). What conclusion, if any, can be drawn about leaf mimicry from this study? What might the researchers do next to further explore the role of leaf mimicry?

Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer.
Write a 1,050- to 1,225-word memo to your colleague.
Include the following in your memo:
An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences
A description of the processes of transcription and translation
An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand
Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder:
Does AML run in families?
What genes are tested for?
Respond to the following in a minimum of 175 words:
What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly?
Provide an example of how you might explain these consequences in terms that patients might understand.
