TR 2.3: Investigating Gene Copies

KWBAT gather evidence from digital models to summarize the effects of an organism’s gene copies on the number of protein instructions provided for the cell.

Review of Key vocabulary!
6

We’ve learned a ton of new words in this unit already! Let’s make sure we have them straight before we move on. Match the vocabulary term with its correct definition.

Draggable itemCorresponding Item
Allele
Instructions for making a protein molecule
Gene
A specific version of a gene
Mutation
Large molecule that performs important functions inside organisms
Feature
a characteristic that all members of a species have
Trait
a specific characteristic of an individual organism
Protein
a random change to a gene that sometimes results in a new trait

Part 2: Second Reading of Hemophilia Article

2

Categorize the correct definition with the term.

  • One type of protein is produced.
  • Two types of protein are produced.

  • Homozygous

  • Heterozygous

For Q3-Q4, Identify if the spider is homozygous or heterozygous for the feature. Then, tell me how many versions of the gene she has. One version (homozygous) or two versions (heterozygous).
2
Anne is_______ for bristle trait because she has _______versions of the gene.
2
Leo is_______for bristle trait because he has_______ versions of the gene.
1
Anne will produce_______
versions of the bristle protein.
Leo will produce _______
versions of the bristle protein,

Part 3: Investigating Gene Copies


Why do some organisms make one type of protein for a feature and others make two?
1

Would the following cell produce one or two proteins for this trait? Explain how you know.


Sentence starter:
This cell would produce (one/two) proteins for this trait.
I know this because....

0

In some cases (like Anne), both copies are the same, so the cell produces only one type of protein. In other cases (like Leo), the copies are different, so the cell produces two types of proteins.


Analyze the diagrams closely. What is causing Leo to make two versions, but Anne only one?

Sentence starter:
Leo has two versions of the bristle protein because...
Anne has one version of the bristle protein because...

Part 4: Sim Missions

Mission 1, Comparing Spiders

LINK TO SIM:


https://apps.learning.amplify.com/traitsandreproduction/#/

Pick a Feature Choose any Feature.

Find Proteins Observe the cells for each spider. Find three spiders that make only one type of protein for this feature.
1

HOMOZYGOUS GENE VERSION:

Find two-three spiders that make only one type (homozygous) of protein for this feature.
Type the name of the spider, the feature, gene pair, and identify its trait.

1

HETEROZYGOUS GENE VERSION:

Find two-three spiders that make two types (heterozygous) of proteins for this feature.
Type the name of the spider, the feature, gene pair, and identify its trait.

Mission 2, Changing Spiders Genes

Using the Sim, pick ONE spider that has a heterozygous gene version for any feature.

I recommend looking at Silk Flexibility.

Then, change something inside of the spiders cells to make the spider produce the same protein.
0

Discuss what changed in the Spider.

What did you do to make the spiders produce the same proteins?

0

How did the change affect the spiders' traits?

Zora is __________ for venom trait because she has __________ versions of the gene.

Zora will produce __________ versions of the venom protein
3
Otis is __________ for venom trait because he has __________ versions of the gene.

Otis will produce __________ versions of the venom protein.

Some organisms make one type of protein a for a feature and others make two because...
