THIS IS THE SITE RECOMENDEND BY THE INSTRUCTOR JUST CHOOSE ONE.

.
Methods of Conjugation: (an animation)

http://www.learner.org/courses/biology/archive/animations/hires/a_infect1_h.html

Some other interesting sites:

http://people.k
u.edu/~jbrown/gene.html (What the heck is a gene?)


Here is a great site that explains DNA Structure:
http://www.johnkyrk.com/DNAanatomy.html be sure to click on the arrows to follow the
animation along.


Here are some interesting links, and within these i
s quite a list of more valid links. Have fun
exploring!


This is Molecules in Motion, and has a variety of great introductions as well as animations that
will help you understand this material better:

2. Discus
s the roles of tRNA; mRNA; in the synthesis of proteins.


3. Distinguish between genotype and phenotype.


4. a. Discuss the mechanisms by which organisms can "exchange" information even across species, be
sure to include a discussion of conjugation, tran
sduction and transformation. b. What would happen if
an organism became genetically "fixed" and could not change their genetic makeup? (this is a 2
-
part
question)


5.What mechanisms do bacteria utilize to repair damage caused by radiation?


6. Discus
s the pros and cons of genetic engineering, include at least three applications.

7.
You are assigned to a jury in a murder case. (what are the details of the crime?) The DNA evidence
is presented (how was it collected and analyzed?). What will you look for

to verify the accuracy of the
DNA testing?

develop a scenario and your conclusions based on DNA evidence

8.
Genetics and genetic engineering. Here is the place where you will put your understanding of DNA,
RNA and protein synthesis to the test.....

9.
Wha
t are your thoughts on recombination? Mutations?

10.

1. Do

the structural differences between eukaryotes and prokaryotes necessarily mean that
their cells are functionally different? Explain your answer, and be sure to include the differences
that do exist between pro and eukaryotic cells. What are your thoughts

about the similarities
between prokaryotic cells and the mitochondria of eukaryotic cells? Incorporate your thoughts
on the possibilities of the endosymbiosis theory in your response.


2. List and discuss at least three ways why algae and fungi are econo
mically important.


3. You open your refrigerator and decide to clean it out. You bravely open a container that has
multicovered fuzz over what was once a wonderful lasagna. How would you identify the types of
organisms growing on your food?


4. Discuss th
e connection between viruses and cancer. What mechanisms would viruses use to
lead to the development of cancer cells?




5.
Are viruses living or nonliving entities? Why are they the "ultimate" parasite?




6.
Prokaryotic and Eukaryotic cells.... what do you

think of protists, and helminthes? Viruses.....
Are they alive???
