BIO 33 SYLLABUS

AUGUST, 2001

EDITION 9.0

 

Dear Student:

               

Biology 33, Introduction to Modern Concepts of Biology, is a one-semester course that emphasizes major biological topics and how they directly influence you and other members of society. This course is highly recommended for non-science major students who expect to transfer to upper level colleges and universities.

 

Various faculty members have actively prepared the topics, laboratories, and other experiences for what we hope will be a dynamic and important course. For some of you, it may be the only course you ever take in the biological sciences while you are at college. For others, because of this course and your new interest in biology, you might decide to take other courses in the biological sciences. You might even perhaps, decide to become a biology major or prepare for a career in the biological sciences.

 

The faculty wants you to succeed and it offers you a number of suggestions that will help you. Make every effort to do the required readings while the topic is being considered in class lectures and discussions. Come prepared for each laboratory experience by reading the introduction for the assigned laboratory. When you are unsure of something, arrange to see the instructor so that he/she can make recommendations or clarify the topic. Prepare to satisfy the objectives that have been given to you for each unit. Be active in your efforts, recognizing that a good portion of the responsibility for learning is yours.

 

Much learning takes place well beyond the classroom. Check local newspaper listings for television programs that are directly related to your efforts in this course. The Nova Series and television specials that focus on nature and biological issues are informative, up to date, and for the most part, well done. Articles in local newspapers (The New York Times on Tuesdays, Science Times) and magazines (Scientific American) provide up-dated writings that will give you more details on many topics that directly affect your life. Visits to the college library and your community library can expose you to many historical writings and readings in the sciences. Once again, you must be an active participant in your learning.

 

We hope that you are as excited about taking this course as we are in offering it. We believe that as a result of this course, you will experience changes in your thinking and actions, and these changes are what education is all about. If you have any difficulty, be sure to communicate with your instructor. If you have any suggestions as to how this course can be improved even more, please convey them to your instructor, or to me.

 

Best wishes in this course.

                                                                                               

Sincerely,

 

                                                                                                Gary Sarinsky

FOCUS ON BIOETHICS

 

Should researchers insist on scientific accuracy by designing long-term trials and withholding unproven drugs from patients on the grounds that untested therapies could do more harm than good?  Or, should they heed compassion and release drugs as soon as they show any hint of effectiveness, running the risk that in the absence of carefully controlled trials, it may never be possible to tell which drugs are actually more effective?                                               

 

 

 

BIOETHICS

OVERVIEW FOR STUDENTS

     "Ethics" is the study of voluntary human actions and whether they are right or wrong.  "Bioethics" is that study as it relates to the life and medical sciences.  As biology students, it is important for you to recognize and analyze bioethical issues, and to use your intelligence to determine what is right and wrong.  As citizens, long after you have completed your formal education, you will face and deal with bioethical issues for the rest of your life.

Recent developments in biology research and biotechnology enables man to interfere with or control life. Although society has the capacity to achieve certain results, the question often is whether it should do so.

1. We may be able to clone humans to achieve various objectives, e.g., to establish an embryo bank from which prospective parents could choose a child with genetic characteristics they desire, or to produce a society of superwomen and supermen. Should we do so?

2.  We have a limited amount of resources for health care. Should we deny health care to persons over the age of 55 years if there is a younger person requiring the same treatment?

3.  Should everyone be compelled to undergo compulsory drug testing?

4.  Should smoking be banned entirely because of the reported effect of "second hand smoke"?

5.  Should health care professionals be required to make  public the names of all persons with diseases which are or are suspected to be contagious?

6. Should trained biologists, particularly genetic engineers, who have demonstrated practical applications of recombinant DNA technology, such as the production of human growth hormone and insulin in microbes, and who have produced an FDA approved genetically altered tomato now being marketed, be limited in their activities because of the concern that the formation of new plant and microbial organisms might some day lead to the creation of new kinds of human beings?

7.  Does the insertion of genes from higher organisms to lower organisms by recombinant DNA technology itself represent interference in evolution?

8.  Do we have the right to interfere with natural selection when we do not know where it will lead?

9.  Recent advances in human genetics provide new methods for diagnosing and treating diseases, and promoting human health.  Walter Eckhart, Ph.D.  of The Salk Institute, raises the following bioethical issues:

".....the new knowledge poses questions about who should have access to information about an individual's genetic makeup, how the information should be used, and what genetic manipulations should be permitted in an attempt to prevent or cure genetic diseases."

 

     Dealing with bioethical issues requires a step-by-step approach.

    1.  To recognize the existence of bioethical issues, because not all biological facts involve bioethical issues.

    2.  Where a bioethical issue exists, you must be able to define or describe the biological facts and principles related to the issue.

    3.   To think about the issue and to decide which course of action appears to be right. In doing so, keep in mind that society and other individuals may make an opposite choice, that the outcome of your choice is uncertain, and that it may turn out that in the long run your choice may prove to be unwise or perhaps even disastrous.

               etc.                        

 

 

2b. Example 1 uses the model above to demonstrate how to make your own bioethical decisions.  Select a bioethical  issue, state the biological facts involved and possible

       opposing courses of action that might be taken to resolve the issue, and discuss why each course of action might be right or wrong.  While you are looking at the format of Example 1, complete Section D by making your own ethical decisions and explaining your reasons for them.

 

   Example 1

 

 A. BIOLOGICAL FACT.  Nicotine damages the organs of the respiratory system.  In addition, recent research suggests that cigarette smoke harms the health of          persons near the smoker.

 

 B. BIOETHICAL ISSUE. Should smokers be prevented from smoking near others in order to protect the health of non-smokers nearby?

 

C. POSSIBLE ACTIONS.

ACTION 1.  Prohibit smoking in the presence of non-smokers.

ACTION 2. Require smokers to warn non-smokers that the smoker intends to smoke, so that the smoker can move away.
