Bio 2 Mid-term Review

Here is the promised PowerPoint, remember to click on the post if you are accessing this from a mobile device.   There is a slide for every objective.  Please use it to study for the exam :)

DNA model continued (pg 53)

Making another 3-D model of DNA with pipe-cleaners and beads.  Notes for this activity go back on pg 53

Fixing previous work

Please don't forget that your notebook is always "fixable".  If you are not happy with your current grade, sign up for advisory to come in and get help, or to have your notebook graded again.  

Also, the "Design a Species" project can still be turned in or fixed.  

Questions? ASK!

Ghost in your Genes

Identical twins share the same genes and are often startlingly alike. Why, then, should they often meet such different fates one twin developing a serious disease like cancer while the other remains unscathed? 

Ghost in Your Genes looks at that question and attempts to answer it.  

You will watch the video and answer 8 questions.  The questions go on page 56 and your answers on pg 57

Once the video is complete, write a paragraph (or bullet points) outlining what you learned and reflecting on why it was important to watch this video on pg 58. 

Then you will read and mark up the text of an article from the Smithsonian Magazine that highlights one of the scientists featured in the film.  This article goes on pg 59.  

3rd Quarter grades

All notebooks and Design a Species projects that were turned in by today 3/13/14 have been graded and entered into the gradebook.  Click on the tab to connect to StudentVue to check your grade.  Remember, if you are not happy with it, you can always fix your notebook and/or project over break and resubmit when we return.  In order to resubmit, you have to come in during advisory to show your new evidence of mastery.  Happy (almost) Spring Break!! :)

DNA Extraction pg 55

Intro questions pg 55

• Where is DNA located in a Eukaryotic cell? (what is a Eukaryotic cell?)
• What would a scientist need to do in order to extract DNA from a eukaryotic cell?

DNA

Today you will extract DNA from some of your cells and learn more about DNA.

Extracting DNA from Your Cells

Cells from the lining of your mouth come loose easily, so you will be able to collect cells containing your DNA by swishing a liquid around in your mouth. 

To extract DNA from your cells, you will need to separate the DNA from the other types of biological molecules in your cells.  You will be using the same basic steps that biologists use when they extract DNA (e.g. to clone DNA or to make a DNA fingerprint).  You will follow these 3 easy steps to extract the DNA:

  Detergent

eNzymes (meat tenderizer)

  Alcohol

 

Getting Your Sample of Cells

Obtain a cup with sports drink.  You will need to get thousands of your cheek cells in the sports drink in order to extract enough DNA to see.  Therefore you should swish the sports drink around in your mouth vigorously for at least one minute. Then spit the drink back into the cup.

Step 1: Detergent

Get a clean test tube. Add a small amount of detergent to a test tube (about 0.25 mL).  Now carefully pour the drink containing your cheek cells into the test tube with detergent until the tube is half full. 

Step 2: Enzymes

Add a pinch of enzyme (meat tenderizer) to your test tube.  Place your thumb over the top of the tube; gently invert the tube five times to mix.  Place the tube in the test tube rack.  Let the mixture sit for at least 10 minutes.  While you are waiting, answer the questions on pg 55.

• Why am I adding detergent?
• Why am I adding enzymes? 
• The protease in meat tenderizer comes from plants, but animals also make proteases.  What is one reason why humans and other animals need to have protein-cutting enzymes?

Step 3: Alcohol

Using a pipette, slowly add cold rubbing alcohol into the test tube; let the alcohol run down the side of the test tube so it forms a layer on top of the soapy liquid. Add alcohol until you have about 2 cm of alcohol in the tube.  Alcohol is less dense than water, so it floats on top.  Do not mix or bump the test tube for 10 minutes.  DNA molecules will clump together where the soapy water below meets the cold alcohol above, and you will be able to see these clumps of DNA as white strands. 

• Why doesn’t the alcohol mix with the water?

DNA Models

Remember, the Design a Species project is due today!

What similarities do you see between each nucleotide?

What makes up a nucleotide?

Color 6 pairs (12 total nucleotides), make sure that the parts that are similar are colored the same.  Cut them out and make a DNA model to put on pg 54.

Bill Nye "The Eyes of Nye"

Today we are going to watch an episode of Bill Nye "the eyes of Nye"
Clones


Please take notes on what you learn from the episode. 
pg 52 Clones


Remember notebook check on the Block day (up through pg 50). We are going to make a DNA model and extract our own DNA!! :) We are also going to take a few minutes to review what we have learned from the quarter to prepare for the midterm.

Design a species projects are due on the block day.  Remember to go back to pgs 41-42 for the directions (you need to have all 5 elements of the project complete). If you have any questions about what needs to be done, please e-mail me (if you don't have my e-mail written in your notebook, then go to the school website, or use studentvue)!

Design a Species (pgs 41-43)

Genetics Project - Design a Species (from biologycorner.com)

Due March 7, 2014

Objective: Genetics follows certain rules, as illustrated by Punnett squares, principles of dominance and recessiveness, and rules related to the location of alleles on the chromosomes. In animals, such as mouse, certain traits are expressed in predictable ways. In this project, you are going to design your own imaginary species, and create traits for the species that follow genetic rules that you have already studied.

The creature should have at least 5 genetic traits from the following list. You are free to create whatever traits you like (such as hair color, size, shape, or other features)

• 2 Single-allele traits
• 1 Codominant trait (or incomplete dominance)
• 1 Multiple allele trait
• 1 Sex linked trait

Your final project should have the following elements:

1. Describe or sketch each of the traits from the list, listing genotypes and phenotypes for each. Partial sketches are fine in this case.

2. Sketch two examples of your creature – one male and one female. The two examples must have different genotypes. Each sketch should have the genotype listed for all traits.

3. Pick one of your single allele traits and create a sample pedigree for your creature. The pedigree should include at least 4 generations.

4. Show a dihybrid cross (using your 2 single allele traits—ex: AaBb x AaBb) List the phenotypic ratios.

5. Create 5 practice problems, using any of the traits. These should be word problems. Do not just write Aa x Aa.

Genetics Project Grading Rubric
	Unsatisfactory (3 pts)	Satisfactory (4pts)	Excellent (5 pts)
Traits and pictures	Some do not follow genetics “rules”, pictures not clear	Follows genetics rules, pictures are small or lacking in creativity or effort	Follows genetics rules, pictures are drawn large and clearly. Colored. Creative.
Creature examples	Genotype doesn’t follow phenotype, pictures not included or unclear	Genotype follows phenotype, all traits included, pictures drawn clearly, neatly, creatively and colored	Genotype follows phenotype, pictures drawn clearly, neatly and creatively, and colored, model of both sexes made (with a key) and shows all traits
Pedigree	Less than 4 generations are shown, significant mistakes in genotypes	4 generations shown, minor mistakes in genotypes	4 generations shown, no mistakes
Dihybrid Cross	Punnett square not set up correctly, phenotypic ratios not given or incorrect	Punnett square set up correctly, minor errors in counting and ratios	Square set up correctly, phenotypic ratios given correctly
Practice problems	Less than 5 problems given, more than 1 is impossible to solve	5 problems given, somewhat unclear or unsolvable	All 5 problems are written well and can be solved

Welcome Back!

Welcome back! Hope everyone had a restful break :)

We ended last semester talking about cells and are going to focus on Genetics this semester.  As we talk about genetics and health, bioethical discussions are going to occur. 
Some things to think about 

• If you could design your own baby (eye color, hair color, height, intelligence, lack of diseases, etc) would you?  Where do you draw the line?
• As we look at diseases, if we could eradicate certain diseases, should we?  
• Is it better to treat the symptoms or try to find a cure?

Before we jump into the study of genetics, we are going to watch a documentary called "Under our Skin".


We will stop throughout the movie and discuss what is happening and why we should care about this disease.

Also, you need a new composition notebook for the new semester by Thursday Jan 9, 2014 :)

Laura's experiment goes on pg 88, your answers on pg 89
It might be helpful to draw a picture of the data (6 circles to represent the petri dishes)

5 second rule re-do

Now that you have something growing, what conclusions can you actually draw? (write your conclusion on pg 87 -- remember to use the rubric)

If you could do it over, would you change your procedures?

Guess what?  We get to do it again!! :)

Edit and revise your procedures as needed.  Do you want to team up with another group?  What might be the benefits or draw backs of having a larger group?

We will run the experiment on Friday! 

Anything visible yet?

Look at plates again.

Information about microbes and identification goes on pgs 84-85

"Mark up the text" on pg 84 "What are microbes?"
