Chapter 11 DNA and Genes And Chapter 13 Genetic Technology

Expectations

 

By the end of the chapter you should have the following completed:

 

1.     Be able to define and give an example when appropriate of:

Group A: nitrogen base, adenine, cytosine, thymine, guanine, Watson and Crick, double helix, replication, uracil, mRNA, tRNA, rRNA, transcription, codon, translation, anticodon,

Group B: point mutation, frameshift mutation, chromosomal mutation, translocation, deletion, insertion, nondisjunction, trisomy

Group C: inbreeding, genetic engineering, transgenic organisms, recombinant DNA, clone, human genome, gene therapy, DNA fingerprinting

2.     All sections of the chapter should be read with the goal of being able to discuss/explain the information contained in them.

11.1 DNA: The molecule of heredity     11.2 From DNA to protein

11.3 Genetic changes                         13.2 Recominant DNA technology

3.     Have the following expectation questions completely answered:

Group 1 DNA: the molecule of heredity and From DNA to Protein

  1. Sketch or describe the structure of a DNA molecule.

  2. Describe the structure of a nucleotide.

  3. The sequence of bases on DNA is GGCAGTTCATGC.  What is the sequence of bases on the complimentary DNA strand?

  4. The sequence of bases on DNA is GGCAGTTCATGC.  What is the sequence of bases on the mRNA that is transcribed from that DNA strand?

  5. Name 3 differences between DNA and RNA.

  6. What is a codon and what does it represent?

  7. What is the role of tRNA in protein synthesis?

 Group 2 Genetic Changes

1.     What is a mutation?

     2.Given the piece of DNA:  CCGATT.  Give an example of the following mutations in that piece of DNA:

    a.  Deletion    b.Insertion (duplication)  c.Inversion    d.Translocation

3.Describe why a mutation of a sperm or egg cell has different consequences than a mutation of a blood vessel cell.

4.Why do you think low levels of mutation might be an adaptive advantage to a species, whereas high levels of mutation might be a disadvantage?

Group 3 Technology and Human heredity

  1. A man is accused of fathering two children, one with type O blood and another with type A blood.  The mother of the children has type B blood.  The man has type AB blood.  Could he be the father of both children?  Explain your answer.

  2. How has recombinant genes aided in the production of less expensive medicine?

  3. How are transgenic organisms different from natural organisms of the same species?

  4. If all the genes that do anything (introns) are the same for humans, how do law enforcement officers use DNA fingerprinting to identify criminals?

 

     4.  Labs to be handed in with discussion questions written out and answered in complete sentences:

RNA and protein construction

5.  Be able to convert a DNA base sequence into the mRNA sequence and then the.

6.  Be able to determine the amino acid sequence in a protein if given the sequence of the DNA or mRNA.  You will  need the secret agent decoder chart for this.  If you have lost yours click on the link to see it.

7.  Know how to convert from one unit to another in the metric system using factor label method.

8.  Record all material covered in class notes and commit them to memory.

 

 

Extra Credit: To be passed in and presented before the test is taken.  Only students that have completed all of their homework for the chapter on time will be eligible.  (maximum 3 pts on test)

 

Genetic engineering is one of the biggest areas of scientific research currently.  It is also one of the most controversial subjects.  Gather 2 articles that support genetic engineering and 2 articles that are against genetic engineering.  Read the articles and decide how you feel.  Use arguments in the articles to support your position.  You will also need to find arguments that counter the arguments the opposing articles are using.  Remember you are trying to convince me your opinion is correct.  Don’t mention arguments that oppose your view unless you have evidence to refute them.  Turn in the articles as well as your typed paper.  Your paper should be typed using 12 pt. font, black ink and having margins of 1-inch maximum.
