Wrap-up study:

Go to the following website:

http://www.ncbi.nlm.nih.gov/books/NBK22266/

At the new page titled Genes and Diseases Chromosome Map, click on one of the 24 chromosomes shown in the image at the top of the page or on the menu list on the right.

Answer the following questions about that chromosome:

1. How many genes does it contain?

2. How many base pairs is it made of?

3. Name one disease associated with this chromosome.

4. Click on and briefly give the characteristics of this genetic disorder.

If all else fails and the URL at the top of the Wrap-up study does not get you where you need to be, try the following:

Alternative1: access the website by using a search engine

1. Search for “ncbi genes and diseases” and select the appropriate link.

2. You should see a page with a book titled “Genes and Diseases”

3. Scroll down through the contents and select “Chromosome Map”

4. Select a chromosome and answer the questions from above.

Alternative 2: use a different website

1. Select the web site below:http://www.ornl.gov/sci/techresources/Human_Genome/posters/chromosome/

2. At the top you will see an image titled “Gene Gateway” listing the human chromosomes. Select one and you will be taken to another page with an image of that chromosome.

3. Scroll over the image and you will see detailed information.

4. Answer the questions from above.Note: For this website, you will have to independently research the disease you choose.
