Textbook Question
Chapter 20, Problem 15PS
Imagine that you have been chosen as the biologist for the design team implementing a self-contained space station to be assembled in orbit. It will be stocked with the organisms you choose, creating an ecosystem that will support you and five other people for two years. Describe the main functions you expect the organisms to perform. List the types of organisms you would select, and explain why you chose them.

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.
