Chapter 10, Problem 5TYU
Summary Introduction
Meiosis is a type of cell division; it produces four cells. Meiosis is involved in the production of gametes. During fertilization, two gametes are fused and produce a zygote, a single cell. The daughter cell contains half the count of chromosome from the maternal origin and the other half the count of chromosome from the paternal origin. There are two stages (meiosis I and meiosis II) occurring in meiosis after the interphase. Meiosis I and meiosis II are involved in nuclear division of the cell followed by cytokinesis. Meiosis produces genetic diversity through crossing over between the maternal and paternal homologous pair of chromosomes and independent assortment of paired chromosomes in meiosis I.

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.
