WELCOME fall 2008 CLASS!

Chapter 1 and accompanying lectures:

ASSIGNMENTS:

Please see the following links for some interesting reading.

LINKS:

For an article about antibiotic resistance published by the FDA go here.

From your textbook company: Watch a video about introduced species.

Also from your textbook company: Watch a video about Darwin and the development of the theory of natural selection.

For an more information about selective breeding you can look at this page.

You can find information about the possible extinction of interdependent species.

I found a site that uses sickle cell trait in the context of natural selection! Go to the page and then scroll down to the bar entitled "sickle cell trait."

What are these Archaea?

Chapter 14: Diversity

You should read this introduction to biodiversity from McGill. Focus on pages 2 & 3.

Chapter 2: A quick overview of biological chemistry.

See this outline.

Chapter 3: The molecules of life.

Gotta know the structure of an amino acid!

The acid on the right is more properly termed a carboxylic acid.

Nice page on lipids!

The importance of the phospholipid can never be stressed enough!

Yes, below is a phospholipid bilayer cake. Now there is somebody who really loved his/her teacher!

Text Box: Yes, below is a phospholipid bilayer cake. Now there is somebody who really loved his/her teacher!

Sparknotes on the phospholipid bilayer.

DNA: gene and chromosome.

Structure of a nucleotide: note the 5-carbon sugar (pentose), the phosphate group and the nitrogenous base.

Here is a copy of one of the lecture handouts.

You should know that chitin is excitin' !

Review the polysaccharides here.

Chapter 4 and accompanying lectures:

The history of study of the cell.

Review the animal cell here.

Cell anatomy?

Cell membrane flash presentation: http://bioweb.wku.edu/courses/Biol120/images/Cell/memb1.swf

You can take a quiz on plant cells here.

Oh, you really want to make sure you have this information mastered.

Chapter 5: Transport across the cell membrane:

THIS TOPIC IS DIFFICULT FOR MANY STUDENTS. PLEASE REVIEW THIS INFORMATION AS FREQUENTLY AS POSSIBLE. SEE THE LINKS ON THE LAB PAGE FOR A LOT OF ILLUSTRATIONS AND EXPLANATIONS!

An illustration of osmosis is here.

A review and animations of various mechanisms of transport across the cell membrane is here courtesy of Pearson/Prentice Hall

Chapter 8: The Cellular Basis of Reproduction and Inheritance

Visualize the cell cycle!

Allele versus gene?

A summary of DNA replication can be followed in the diagram below.

How a gene is activated:

A PowerPoint from the past covering material from chapter 8.

Images of meiosis:

Image 1 Image 2 Image 3 Image 4 Image 5 Image 6 Image 7

A meiosis tutorial can be found here.

An Acess Excellence graphic and short explanation.

Meiosis animation from McGraw Hill.

Chapter 9: Patterns of Inheritance

Short flash animation illustrating the genetics of hair color. http://bioweb.wku.edu/courses/BIOL115/Wyatt/flash/genetics2.swf Good for visualizing basic concepts!

Chapter 12: DNA technology

DNA Fingerprinting in Human Health and Society

RFLP used in a micro context.

Chapter 21: Unifying Concepts of Animal Structure and Function

Other

If you want to jump ahead, you can view the notes from another class who used the same text at http://www.biology.iupui.edu/biocourses/N100/2k2ch8.html

A site that explains the connection between mitosis and cancer is found at http://www.intouchlive.com/home/frames.htm?http://www.intouchlive.com/cancergenetics/index.htm&3 You will find that this site also outlines mitosis and protein synthesis.

Mitosis

For a diagram of the process of mitosis, please see

http://www.accessexcellence.org/AB/GG/mitosis.html

Please see this page for a well-written description of the stages of mitosis http://www.life.umd.edu/CBMG/faculty/wolniak/wolniakmitosis.html#Stages_Anchor

You may review mitosis and the cell cycle at http://www.biology.arizona.edu/cell_bio/tutorials/cell_cycle/main.html

A detailed description of the stages of mitosis is located here http://www.life.umd.edu/CBMG/faculty/wolniak/wolniakmitosis.html

Meiosis

The next link is to a site that introduces meiosis. It not only gives an overview, but has animated graphics of the process, and still pictures of cells as seen under the microscope. You should use this site!

http://www4.ncsu.edu/unity/users/b/bnchorle/www/intro.htm

You do NOT need to know the 5 substages of prophase I.

Here is a quick animation of crossing over. Note: the exchange of genetic information is not represented by an exchange of colors, but by an exchange of letter. You need to watch more carefully than if it were simply colors.

Another site http://tutor.lscf.ucsb.edu/mcdb/tutorial/meiosis/meiosis.htm illustrates meiosis and genetic variation in great detail. It requires shockwave. It may take a "long" time on some computers, but the details and animation are well worth it!

And, as always you can visit http://www.biology.arizona.edu/cell_bio/tutorials/meiosis/main.html for helpful information on many topics. This link will bring you to the meiosis tutorial.

Genetic mutations

Triplo-X syndrome? See http://www.triplo-x.org/doc.asp?document_id=1698

Turner's, Klinefelter's and XYY are found here http://www.gender.org.uk/about/04embryo/42_gnerr.htm

Check out a site that discusses genetic diseases.

Genes and disease.

Is it possible for humans to have two differently-colored eyes? Yes.

Protein synthesis
