GATTACA biology worksheet exploring genetic engineering and ethics from the film.

To solve this worksheet, we need to look at the clues provided in the questions. The title "GATTACA" refers to a famous science fiction movie about genetics. In this movie, society is divided into two groups based on their DNA: "Valids" (people born with perfect genes) and "In-Valids" (people born naturally with imperfect genes).

Here is the step-by-step breakdown for each question:

1. What are Valids vs. In-Valids?
* Reasoning: The movie's premise is that rich parents can edit their babies' genes to make them perfect (tall, smart, healthy). These are "Valids." People born without this editing are "In-Valids" (or "Degenerates").
* Answer: Valids are people genetically engineered to be superior. In-Valids are people born naturally with genetic flaws.

2. How long is Vincent supposed to live? What would be the probable cause of his death?
* Reasoning: At the beginning of the story, a genetic test predicts Vincent's future because he is an "In-Valid." The nurse tells his parents his life expectancy is 30.2 years. The most likely medical issue cited is heart failure.
* Answer: He is expected to live 30.2 years. The probable cause of death is heart failure.

3. Why was Anton surprised to see his brother when they were adults?
* Reasoning: Anton was a "Valid" (engineered to be strong and tall), while Vincent was an "In-Valid" (expected to be weak). However, Vincent grew up to be taller than Anton and beat him in swimming contests, which shouldn't have been possible according to their genes.
* Answer: Because Vincent, who was supposed to be inferior, was actually taller and stronger than Anton, the genetically superior brother.

4. What is Vincent’s real name? What is Jerome’s real name?
* Reasoning: The main character takes on the identity of a former swimming champion to get into space. The champion's name is Jerome Morrow. The main character's birth name is Vincent Freeman.
* Answer: Vincent’s real name is Vincent Freeman. Jerome’s real name is Jerome Eugene Morrow.

5. What does it mean that Vincent’s parents are keeping him from achieving his dreams?
* Reasoning: His parents accepted the genetic prediction that he was flawed. They didn't encourage him to aim high (like going to space) because they believed his DNA made it impossible. They treated him as fragile.
* Answer: It means they limited his ambitions and treated him as weak because they believed his "bad" genes meant he couldn't succeed.

6. What was Vincent’s dream as a child?
* Reasoning: Throughout the film, Vincent looks up at the stars and wants to leave Earth. He wants to join the Gattaca Aerospace Corporation.
* Answer: To go to space / become an astronaut.

7. What did Irene do to get to “Gattaca”?
* Reasoning: Irene is a "Valid," but she has a small genetic flaw (a heart condition risk). She hides this flaw to keep her job at the elite agency. She likely had to undergo strict screening or hide her medical records. *Correction/Refinement:* In the context of the plot, she didn't "fake" her way in like Vincent; she was hired because her genes were mostly good enough, but she lives in fear of being fired if her minor defect is found. However, usually, this question asks how *Vincent* got there. If it strictly asks about Irene, she got there by having "valid" genes, though she hides a heart defect. Let's look closer at the prompt style. Usually, these questions contrast the characters. Irene got there through her genetic status (Valid), whereas Vincent had to cheat.
* Answer: She was hired because she is a "Valid" (genetically superior), although she hides a minor genetic defect (heart condition) to keep her position.

8. What did Irene do to get to “Gattaca”? *(Note: Question 7 and 8 seem similar in the image text, let's re-read carefully. Ah, Q7 asks "What was Vincent's dream?" and Q8 asks "What did Irene do...". Wait, looking at the image again: Q7 is "What was Vincent's dream as a child?". Q8 is "What did Irene do to get to 'Gattaca'?". My previous reasoning for 7 was wrong, I swapped them. Let's fix.)*
* Re-evaluating Q7: Vincent's dream was to go to space.
* Re-evaluating Q8: Irene is a navigator at Gattaca. She got there because her genetic profile was good enough to be hired as a Valid. She didn't have to steal an identity like Vincent.
* Answer: She used her own valid genetic profile to get hired, though she hides a slight probability of heart trouble.

9. What physical changes did Vincent make to “become” Jerome? Give at least 2.
* Reasoning: To pass as Jerome, Vincent had to change his appearance and his biological signature.
1. He scrubbed his body to remove his own skin cells/hair.
2. He wore contact lenses to change his eye color/retina scan.
3. He used fake finger tips or rubbed Jerome's blood/urine/skin on himself to pass DNA tests.
4. He underwent leg lengthening surgery (mentioned in the movie backstory) to grow taller.
* Answer: 1. He scrubbed his body daily to remove his own DNA (skin/hair). 2. He wore special contact lenses to alter his eye scans. (Also acceptable: He underwent surgery to lengthen his legs).

10. List at least three ways that Vincent tricked the people at GATTACA into believing he was Jerome.
* Reasoning: This is similar to Q9 but focuses on the "tricking" aspect during his workday.
1. He carried Jerome's urine/blood samples in false containers to pass random drug/DNA tests.
2. He rubbed Jerome's skin cells all over his body before entering the facility.
3. He memorized Jerome's personal history and swimming records to answer questions correctly.
* Answer: 1. He used Jerome’s blood and urine samples to pass DNA tests. 2. He scrubbed his body with sandpaper/brushes to remove his own skin cells. 3. He wore contact lenses to match Jerome’s eye pattern.

11. What one thing kept Vincent from failing to reach his goal?
* Reasoning: This is the main theme of the movie. Vincent says, "I never saved anything for the swim back." He succeeded not because of his genes, but because of his willpower and determination. He refused to accept the limits placed on him.
* Answer: His determination and willpower (he refused to give up, even when it seemed impossible).

Final Answer:

1. Valids are people genetically engineered for perfection; In-Valids are people born naturally with genetic flaws.
2. 30.2 years; probable cause is heart failure.
3. Anton was surprised because Vincent was taller and stronger than him, despite Vincent being an "In-Valid."
4. Vincent’s real name: Vincent Freeman. Jerome’s real name: Jerome Eugene Morrow.
5. They limited his ambitions and treated him as fragile because they believed his genes determined his failure.
6. To go to space (become an astronaut).
7. She was hired as a Valid due to her superior genetics (though she hides a minor heart defect).
8. *(Note: If Q8 is distinct from Q7 in your specific class notes, it usually refers to her hiding her defect. If Q7 and Q8 are swapped in my reading, Q7 is Dream=Space, Q8 is Irene=Used Valid Genes).*
9. Two physical changes: Leg lengthening surgery and scrubbing off his own skin/DNA (or wearing contact lenses).
10. Three ways he tricked them: Used Jerome’s blood/urine samples, rubbed Jerome’s skin cells on his body, and wore contact lenses to bypass eye scans.
11. His determination/willpower (he never saved anything for the swim back).
