Gathering Evidence about Genes

OBJECTIVE: KWBAT explain the role of genes by constructing models of protein molecules and simulating mutations.
Part 1

Part 1: Do Now

The Darwin’s bark spider on the left makes proteins that result in spider silk with high flexibility.

The Darwin’s bark spider on the right makes proteins that result in spider silk with low flexibility.

Both have the same parents.

Predict: Using the space below, Why do organisms make different proteins?

If two birds have the same protein for feather color, how must their proteins be functioning inside the cell?

If two people have different proteins for hair color, what must be true about the protein molecules inside the cell?

Part 2: Exploring Genes in the Sim

Launch the Sim. Then, follow the steps below.
  1. Press on any spider.
  2. Select a feature. Notice the traits and proteins the spider has for this feature.
  3. Press on the black boxes in the upper right corner of the screen to change the gene versions.
  4. Look for evidence that genes are instructions for proteins. Then, answer the questions below.

What Spider and what feature did you observe?

What did you observe in the cell when you changed the spider’s gene versions?

Sentence Stem:
I noticed that when I changed the spider's gene versions...

Do you think what you observed is evidence that genes are instructions for proteins? Why or why not?

(Hint: Did the trait change when you changed the gene? Why did the trait change?)

How many proteins are needed for your blood to clot?

Find a quote that answers this question:

What happens when proteins connect and work together?

People with hemophilia are missing two proteins needed for blood clotting.

Fill in the blank.

Different _____ carry instructions for making different ______.

Different versions of genes are called...

How many copies of genes does an organism have for one feature?

Match the definition with the correct term.

  • Same version of the gene copy.
  • Different versions of the genes.
  • One type of protein produced.
  • Two types of protein produced.

  • Homozygous (same)

  • Heterozygous (different)

What does it mean when a person does not have the right instructions for the clotting factor protein?

Match the definition to the correct term based on this paragraph.

Trait
gene

Genes are instructions for building protein molecules.

Find a quote that answers this question.

How is hemophilia caused?

Match the terms!

Homozygous
Heterozygous

How do doctors treat people with hemophilia?

Summarize this paragraph in 1-2 sentences.

As long as the cell has the gene with instructions to make a protein, the cell will make the protein.

Working to replace or genes is called....

Part 4

Part 4: Exit Ticket

Directions: Below are two possible scenarios for the spider named Anne. Analyze each scenario, and answer the questions below.


Scenario A -

Body Color Genes C3 C3

Scenario B -

Body Color Genes C3 C1
Hint: look at the GENES.

Where are genes located in each cell?

What do you observe in the cell when Anne’s gene versions are changed in Scenario B?

Do you think what you observed is evidence that genes are instructions (if you change the gene, you change the protein) for proteins? Why or why not?
