Amoeba Sisters Video Recap-DNA, Chromosomes, Genes, and Traits: An Intro to Heredity - Build the Vocabulary Table

Sep 28, 2026

Uploaded by Connor

A heredity-focused video recap worksheet builds foundational vocabulary for understanding how DNA, chromosomes, genes, and traits relate. Students complete a structured table with definitions, significance, and real-life examples, then answer diagram- and reasoning-based questions about nucleotide counting, DNA base types, and how DNA bases connect to traits. Additional activities ask students to interpret images showing where DNA code is located, apply inheritance logic to a character, and consider how the environment such as nourishment or UV light can influence traits.

Amoeba Sisters Video Recap-DNA, Chromosomes, Genes, and Traits: An Intro to Heredity The vocab below builds a foundation for understanding heredity! Complete the table using your own words and creativity. | Name | Illustrate! | Explain it in Your Own Words | What’s its Significance?(Why does it Matter?) | Real Life
Example | | --- | --- | --- | --- | --- | | DNA | 1. | 2. | 3. | DNA found in the body cell of a snake | | Chromosome | 4. | 5. | Chromosomes allow the large amount of DNA to be compacted. One reason this is significant is in cell division as it makes it much easier for the cells to put these units into the new cells. | 6. | | Gene | 7. | 8. | 9. | One of many genes that can code for a protein involved in eye pigment | | Trait | 10. | 11. | 12. | 13. | | 14. For the diagram at right, please label the following words on the diagram.
(A) Deoxyribose (sugar),(B) Phosphate, and (C) Nitrogenous Base.
15. Based on the definition, how many nucleotides do you see in this diagram?
16. What are the four different types of bases in DNA and how do they pair?
17. When studying heredity, what is the relationship of DNA bases and traits? | ____

18. Explain what this image represents regarding where your entire DNA code can be found.
| | | | | --- | --- | --- | --- | | 19. Apply Your Understanding
Spike is not a clone of his father. He inherited DNA from both of his parents. Chromosomes are condensed units of DNA. If Spike has 36 chromosomes, you would expect that Spike would have inherited chromosomes from his mother and chromosomes from his father.
20. How did you determine the chromosome numbers and how does that relate to heredity?

The example of nourishment was used in the case for Spike, as this could affect his growth and size. This can also occur in humans. UV light was not mentioned in the video. How could UV light potentially affect an organism’s trait? Provide one example. | | | | | | | | | | 22. Recap the Vocab

FAQs

What vocabulary words must students define and illustrate in the worksheet?

Students work with DNA, chromosome, gene, trait, nucleotide, phosphate, deoxyribose (sugar), and nitrogenous base, filling in definitions, significance, and examples in a table.

How do students determine nucleotide or base information from a DNA diagram?

They are asked to count nucleotides in the provided diagram and explain the four DNA base types and how the bases pair.

How does the worksheet connect heredity to environment?

It describes how environmental factors like nourishment can affect an organism’s traits and asks for one example of how UV light could potentially influence a trait.
