Textbook Question
Chapter 1, Problem 1CC
If a person eats 12 milligrams (mg) of salt in a day and excretes 11 mg of it in the urine, what happened to the remaining 1 mg?
Expert Solution & Answer
Summary Introduction
To determine: The fate of 1 milligram of urine if a person’s intake of salt is 12 milligram and excretion of salt is 11 milligram.
Introduction: Excretion can be defined as the removal of waste material or substances from the body generally by means of feces, urine, skin, or lungs. The main organ for the removal of waste material from the body is the kidney.
Explanation of Solution
When a person consumes 12 milligrams of salt and excretes 11 milligrams of salt by excretion process, the remaining 1 milligram of salt will retain inside the body of that person. This remaining amount of salt will metabolize into a new type of substance.
Therefore, 1 milligram of the salt will retain inside the body of the living organism if it intakes 12 milligrams of salt and excretes 11 milligrams of salt.

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.
