Chapter 10, Problem 14P

The figure that follows shows part of a modified screen shot of part of the human genome as displayed on the UCSC Genome Browser. A through G map the sequences within individual cDNA clones to the genome sequence. Refer to the key in Fig. 10.3 if you need help in interpreting this diagram. Pay close attention to the vertical widths of the icons indicating exons.

Chapter 10, Problem 14P, The figure that follows shows part of a modified screen shot of part of the human genome as

  1. How many annotated genes do you think are present in this region of the human genome?

  2. For all annotated genes in this region, indicate whether they are transcribed in the direction from centromere to telomere or from telomere to centromere.

  3. How many promoters are suggested by the data? Approximately where are these promoters located?

  4. How many different proteins are encoded by the DNA sequences in this region?

  5. What is unusual about this region of the human genome?

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.
