UMUC Biology 102/103 Lab 5: Meiosis

This contains 100% correct material for UMUC Biology 103 LAB05. However, this is an Answer Key, which means, you should put it in your own words. Here is a sample for the Pre lab questions answered:

Pre-Lab Questions

 

 

 

1. What major events occur during interphase?

 

The cell functions at its job, and prepares for mitosis by collecting resources and duplicating organelles (G1) and genetic content (S), then creating proteins needed for nuclear division (G2).

 

 

 

2. A person, residing in a location where they are exposed to the sun often, develops a mutation in some of their skin cells resulting in cancer. Consider whether their offspring will be born with the same mutation. Use scientific evidence to support your answer.

 

 

 

It would be highly unlikely that the person’s offspring will be born with same skin cancer mutation because the mutation occurred in the person’s skin cells. Skin cells are somatic cells (body cells) and are not involved in meiosis or reproduction. For the mutation to be passed on to the offspring, a sex cell (sperm or egg) would have to carry the mutation.

 

The other questions that will be answered:

Post-Lab Questions

 

1.    What is the ploidy of the DNA at the end of meiosis I? What about at the end of meiosis II

2.    How are meiosis I and meiosis II different?

3.    Why do you use non-sister chromatids to demonstrate crossing over?

 

4.    What combinations of alleles could result from a crossover between BD and bd chromosomes?

 

 5.    How many chromosomes were present when meiosis I started?

 

 6.    How many nuclei are present at the end of meiosis II? How many chromosomes are in each?

 

 7.    Identify two ways that meiosis contributes to genetic recombination.

 

8.    Why is it necessary to reduce the number of chromosomes in gametes, but not in other cells?

 

 9.    Blue whales have 44 chromosomes in every cell. Determine how many chromosomes you would expect to find in the following:

 

 

 

                                  i.    Sperm Cell:

 

 

                                 ii.    Egg Cell:

 

 

 

                                iii.    Daughter Cell from Mitosis:

 

 

 

                               iv.    Daughter Cell from Meiosis II:

 

 

 

10.  Research and find a disease that is caused by chromosomal mutations. When does the mutation occur? What chromosomes are affected? What are the consequences?

 

 

 

 

 

 

 

11.  Diagram what would happen if sexual reproduction took place for four generations using diploid (2n) cells.

Post-Lab Questions

 

1.    Record your hypothesis from Step 1 in the Procedure section here.

 

 

 

 

 

 

 

2.    What do your results indicate about cell cycle control?

 

 

 

 

 

 

 

3.    Suppose a person developed a mutation in a somatic cell which diminishes the performance of the body’s natural cell cycle control proteins. This mutation resulted in cancer, but was effectively treated with a cocktail of cancer-fighting techniques. Is it possible for this person’s future children to inherit this cancer-causing mutation? Be specific when you explain why or why not.

 

 

 

 

 

 

 

4.    Why do cells which lack cell cycle control exhibit karyotypes which look physically different than cells with normal cell cycle.

 

 

 

 

 

 

 

5.    What are HeLa cells? Why are HeLa cells appropriate for this experiment?

UMUC Biology 102/103

Lab 4: Enzymes

 INSTRUCTIONS:

 

 

 ·         On your own and without assistance, complete this Lab 4 Answer Sheet electronically and submit it via the Assignments Folder by the date listed in the Course Schedule (under Syllabus ).

 ·         To conduct your laboratory exercises, use the Laboratory Manual located under Course Content. Read the introduction and the directions for each exercise/experiment carefully before completing the exercises/experiments and answering the questions.

 ·         Save your Lab 4 Answer Sheet in the following format:  LastName_Lab4 (e.g., Smith_Lab4) .

 ·         You should submit your document as a Word (.doc or .docx) or Rich Text Format (.rtf) file for best compatibility.

 

 

 

 

 

Pre-Lab Questions

 

 

 How could you test to see if an enzyme was completely saturated during an experiment?

 

 

 

 

 List three conditions that would alter the activity of an enzyme. Be specific with your explanation.

 

 

 

 

 Take a look around your house and identify household products that work by means of an enzyme. Name the products, and indicate how you know they work with an enzyme.

Saliva:

 

 

 

 

 

Post-Lab Questions

 

What were your controls for this experiment? What did they demonstrate? Why was saliva included in this experiment?

 

 

 

What is the function of amylase? What does amylase do to starch?

 

 

 Which of the foods that you tested contained amylase? Which did not? What experimental evidence supports your claim?

 

 

  Saliva does not contain amylase until babies are two months old. How could this affect an infant’s digestive requirements?

 

 

 

There is another digestive enzyme (other than salivary amylase) that is secreted by the salivary glands. Research to determine what this enzyme is called. What substrate does it act on? Where in the body does it become activated, and why?

 

 

 

Digestive enzymes in the gut include proteases, which digest proteins. Why don’t these enzymes digest the stomach and small intestine, which are partially composed of protein?

Post-Lab Questions

 What reaction is being catalyzed in this experiment?

  What is the enzyme in this experiment? What is the substrate?

  What is the independent variable in this experiment? What is the dependent variable?

  How does the temperature affect enzyme function? Use evidence from your data to support your answer.

  Draw a graph of balloon diameter vs. temperature. What is the correlation?

  Is there a negative control in this experiment? If yes, identify the control. If no, suggest how you could revise the experiment to include a negative control.

  In general, how would an increase in substrate alter enzyme activity? Draw a graph to illustrate this relationship.

 

Design an experiment to determine the optimal temperature for enzyme function, complete with controls. Where would you find the enzymes for this experiment? What substrate would you use?

 

Discussion Two

  

A three-month-old baby boy comes into your clinic with the main complaint that he frequently vomits after eating. He often has a swollen upper belly after feeding and acts fussy all the time. According to his parents, the vomiting has become more frequent this past week and he is beginning to lose weight. After careful history taking, a thorough physical exam and diagnostic work-up, the patient is diagnosed with pyloric stenosis.

1. What is the etiology of pyloric stenosis?

2. Describe in detail the pathophysiological process of pyloric stenosis.

3. Identify hallmark signs identified from the physical exam and presenting symptoms. What diagnostic tests would help to confirm the diagnosis of pyloric stenosis?

4. Describe the pathophysiology of complications of pyloric stenosis.

5. What teaching would you provide this patient/parents regarding pyloric stenosis?

In addition to the textbook (McCance, K. L., Huether, S. E., Brashers, V. L., & Rote, N. S. (2013). Pathophysiology: The biologic basis for disease in adults and children (7th ed.). St. Louis, MO: Mosby)utilize at least one peer-reviewed, evidence based resource to develop your post.
