Course Information

Biology 189 is a comprehensive, freshman-level biology course which serves as a prerequisite for other biology courses in the biology degree program (e.g. anatomy, physiology, microbiology).  It serves to build a cornerstone of biological knowledge for all students in the health field.  The topics include biochemistry, cell structure and function, metabolism, genetics, gene expression, evolution, and ecology.  Biology 189 is a 4-credit, lecture and lab course.  It includes 3 hours of lecture and 3 hours of lab per week.

NOTE:  (1)  Students who score below 80 on the reading placement test available in the testing center or below 70% on the Bio. 095 Diagnostic Exam,  may wish to consider enrolling in Bio. 095 before taking Biology 189.  (2)  A delayed section of Bio. 095 (Sec. S01)  will begin 02/25, and will continue through the rest of the semester.  Students who would like to transfer from Bio. 189  into Bio. 095 may do so with no additional tuition or fees, other than the purchase of a new textbook.  To transfer to 095 call the biology department at 702.651.5973.  Do not drop the course through registration.


1.  REQUIRED: Biology, 8th edition, by Campbell and Reece, Benjamin Cummings Publishing.  ISBN-13: 9780805371468
2.  REQUIRED:  Biology 189 Laboratory Text.  This can be purchased from the college bookstore



Course Objectives

Upon completion of the course, the student will have a general understanding of:

1.  The process of scientific inquiry and the defining properties of life.
2.  The properties of the major classes of biologically important molecules.
3.  The basic organization and structure of cells.
4.  The properties and function of cell organelles and membranes.
5.  Enzyme properties and basic thermodynamics as they apply to cellular energetics.
6.  The processes of energy acquisition and transformation: cellular respiration and photosynthesis.
7.  The basic principles of cell signaling and communication.
8.  The processes of cell division for somatic growth and sexual reproduction.
9.  Genes, alleles, and patterns of genetic inheritance.
10.  Chromosome structure and the physical/chemical properties of DNA.
11.  Molecular genetic processes:  replication, repair, transcription, translation, and mutation.
12.  DNA technologies.
13.  Early earth conditions and the origin of cells.
14.  The biology of prokaryotes.
15.  Viruses and bacteria as basic models for understanding molecular genetic processes.
16.  The regulation of gene expression.
17.   The fundamental principles of evolution:  evidence, mechanisms, phylogenies, and diversity.
18.  The relationships of form and function among diverse cell and body plans.
19.  The basic principles of ecology.


    A tentative lecture schedule is provided.  Any significant changes in the lecture or exam schedule will be     announced in class, and will be available on the course website. You are responsible for this     information, even if you are absent.  Lecture topic information missed due to absence must be obtained     from students in the class.  While I am happy to help you with specific questions you may have after     studying the material you missed,  I am not able to review entire missed lectures with students.

Classroom Policy

Phones and beepers must be turned off and put away during class.  Please arrive on time, and avoid coming and going during class.  Although food is not allowed in the classroom, beverages are permitted.  During class no electronic devices are permitted except for those authorized by your instructor. 

Cheating, plagiarism, and other acts of academic dishonesty are held as serious offenses.  Instructors have the responsibility to report any such incident in writing to the Vice President for Academic Affairs.  Serious penalties may be imposed which, depending on the nature of the incident, could range from grade reductions to permanent expulsion from the class or the college. 
You are not allowed to leave the classroom during quizzes or exams for any reason.


This lecture poses no unusual safety hazards.  Emergency information is posted by every exit door.


The total points you accumulate during the semester will determine your final grade.  Points are contributed in the following areas:


 4 exams*
400 pts
 4 quizzes*
 40 pts
 Laboratory 205 pts
 Final exam (comprehensive)
 145 pts
 Total 790 pts**


**There is no ‘extra credit’ allowed in the Biology Department under any circumstances.

Final grades will be assigned following a standard grading scale:

Points*         Percent      Grade
711 - 790       90-100        A
632 - 710       80-89          B
553 - 631       70-79         C
474 - 552       60-69         D
0    -  473       0-59           F
Exams and scoring

1.  There will be 5 hourly exams – each is worth 100 points (lowest score dropped).
2.  The exams will typically consist of objective (multiple choice) questions.  However, the instructor may     also include a combination of objective and essay questions, or be entirely essay questions – a change in     the format of the exam will be announced prior to the exam date.
3.  There will be five, short, in-class quizzes (lowest score dropped), although the instructor may choose to proctor these online rather than in-class.  Any change in the format will be announced in class well before the date of the quiz.
4.  Questions, problems, or challenges to exam/quiz questions must be presented within one week of the day on which the scores are returned to the student.  All assignment grades will be considered final after that time.
5.  The final exam will be comprehensive.  It will be worth 145 points.
6.  Many exam questions will require not much more than simple recall, while others will require the student to put principles together to solve a problem.  Material for examination may be taken from the lecture, lecture notes, textbook, and any combination thereof.
7.  Failure to properly fill out the ‘scan-tron’ sheet will result in loss of one point for the exam/quiz in question.



You are registered for 1 of numerous lab sections.  You  must attend the lab in which you are officially enrolled.   Students are expected to attend and to be punctual.  No makeup quizzes, and no lab section switching will be allowed without permission of the receiving instructor.  Your lab instructor will describe specific policies and procedures on the first day of your lab section. 

There is only one grade for Biology 189.  Your lab score will combine with your lecture scores at the end of the semester to create the final grade.
