Review: Exam #3 - F'07 

General:
    The format of this exam will be very similar to the previous exams.  It will be include a mixture of objective (e.g., multiple choice, definition, fill-in-blank) and subjective (short answer) questions.  You will need a pencil to fill in the computer-scored sheet for the multiple choice questions.  You may use a pencil or pen for the remainder of the exam (but I strongly recommend pencil).  The exam is designed to last one hour.  In general, the exam could include:  (1) anything covered in class; and (2) any study sheets, articles, handouts or other materials used/assigned in class.  I try to ask an equal number of questions about each class.  

    The main topics that we covered that will be included on this exam are photosynthesis, cell cycle, mitosis, meiosis and genetics.  To help prepare for the exam you may want to check out:  (1) questions at the end of each chapter in the textbook; (2) the quizzes from the website for the textbook; (3) my past exams (posted online); and (4) my study guides.  As you know, i think concept maps are a great way to prepare for exams.  For example, can you create a concept map with the following terms/concepts/ideas:  gene, allele, locus, phenotype, genotype, homozygous, heterozygous, test cross, linkage, crossing over, tetrad (bivalent), chiasma, Punnett square, 3:1 ratio, 1:1 ratio, 9:3:3:1 ratio, 1:1:1:1 ratio, sex-linked, P, F1, F2?

     As a general rule, the exam questions come directly from the notes & in class activities.  Thus, focus on getting a good set of notes during class.  Use the "Presidential Notes" and online notes for each topic as general guides to what is important.  Use the textbook primarily as a reference to help understand what we discussed in class.  

Photosynthesis - This unit describes the process by which plants produce carbohydrates in the chloroplast. 

• Text - Chapter 8.  Use the text as a reference to help understand class material.  Ignore "photosynthetic variations (8.4)".

• Presidential "Notes" were handed out in class.

• Lecture notes are posted online.   You may want to review the notes on bioenergetics to provide a little background on oxidation, reduction, phosphorylation, etc.

• Check out the Photosynthesis classics and Concept Map & terms

Cell Cycle - This unit describes the general cell cycle and mitosis.

• Text:  9.4 (just the highlights) and chapter 15

• Cell cycle "Presidential Notes" given in class

• Lecture notes posted online.  You may want to study the diagrams of mitosis and meiosis that are posted on line.

• Cell division study guide posted online.

• Check out the concept map.

• Check out the Cell division questions posted on line.

Cell Sex & Meiosis - This unit features the process of sexual reproduction at the cellular level and the mechanism of meiosis.

• Text - Ch 15

• Meiosis/Cell Sex "Presidential Notes" given in class

• Check out the online lecture notes.

• Check out karyotypes

Genetics - This unit highlights mechanisms of inheritance.

• Text - Chapter 16 & 17

• Two "Presidential Notes" given in class.

• Online lecture notes

• Assorted genetics problems on line.

• Genetics study guide available on line.

• Corn exercise - understand the basics

• Single gene traits in humans (don't memorize but just understand - PS there was a mistake in this document; please note that hitch-hiker's thumb is recessive not dominant.  Thanks Rob.)  You do not have to memorize whether a given trait is dominant or recessive.  I will either provide that information or will ask you to figure it out based on the information I provide.
