Introduction to Genes
Embedded Files
EOU Exam on Thursday, May 1st
Learning Intention:
Learning Intention:
Explore how genes influence characteristics in living organisms and discuss how gene editing, like in the CRISPR twin case, can alter these instructions."
Success Criteria:
Success Criteria:
I am successful when I can...
1. Engage – I can describe the CRISPR twin case and identify the key question: How do genes determine traits?
2. Explore – I can examine examples of inherited traits and recognize that they are controlled by genes found in DNA.
3. Explain – I can define genes as segments of DNA that code for proteins and explain their role in determining traits in living organisms.
4. Elaborate – I can connect my understanding of genes to real-world applications, such as gene editing, and discuss potential benefits and risks of altering DNA.
5. Evaluate – I can demonstrate my understanding of genes by explaining how a specific gene, like CCR5, can influence traits and disease resistance.

Our Unit Story
In 2018, news broke around the world about a groundbreaking—and highly controversial—experiment in China. A researcher named He Jian (He-JEE-ahn) used CRISPR gene-editing technology to alter the DNA of twin baby girls before they were born. His goal was remarkable: to make these twins immune to HIV, a virus that can lead to the serious disease AIDS.
He Jian (He-JEE-ahn) and his team focused on editing a gene called CCR5. Normally, this gene codes for a receptor that helps HIV enter human cells. By editing this gene in the embryos, the researcher hoped to create a natural immunity to HIV for the twins. When the twins, nicknamed Lulu and Nana, were born, they became the first genetically modified humans in history.
Your task: You will be taking on the role of a GENETICIST, a scientist who specializes in the study of genes and heredity. You are tasked with investigating the problems and implications of editing human genes. As you learn about genetics, consider the scientific and ethical questions surrounding CRISPR technology. What are the potential benefits and risks? Should there be limits to how scientists use gene editing? Prepare to analyze real-world scenarios and form your own conclusions based on evidence.

Take-Away
Stop n'Jot
Genes: short pieces of DNA that carry specific genetic information.
Traits: Characteristics, such as eye color, hair color and blood type, that are passed on to children through their genes.
Inherited: what was passed on from parents in the form of genetic information
Gene Expression: process where the instructions in a gene are used to make a protein. Not all genes are active all the time—some get turned on or off depending on what the body needs.
Interactions: When two or more things effect one another.
