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.

inherited from parents, is in almost all of body's cells

3. determines traits through code

of nucleotides

two strands of nucleotides which

pair in the middle

DNA found in the body cell of a snake

Chromosome 4.

Gene

7.

Trait

10.

5.DNA is packaged into

Chromosomes allow the large

chromosomes

amount of DNA to be

specific genes can be found on compacted. One reason this is

DNA

significant is in cell division as

it makes it much easier for

the cells to put these units

into the new cells.

8. made of portions of DNA, that 9.code for proteins, which have

code for genes;

a big role in affecting traits

can be turned on or off

6.

human body cells have 46 chromosomes sperm has 23; egg has 23.

One of many genes that can code for a protein involved in eye pigment

11.

a characteristic of a living

organism

12.

this affects the organism's appearance, behaviour, its biochemistry, how it is perceived by other members of the same species...everything about it!

13.

Patterns on snake's body; size

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? _6___ 16. What are the four different types of bases in DNA and how do they pair?

adenine (A) thymine (T) guanine (G) cytosine (C) A-T; G-C

17. When studying heredity, what is the relationship of DNA bases and traits?

The sequence of the bases can code for traits

A Picture Says It! 18. Explain what this image represents regarding where your entire DNA code can be found.

Every body cell contains a complete copy of that organism's DNA, within its

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 _1_8____ chromosomes from his mother and _1_8____ chromosomes from his father.

20. How did you determine the chromosome numbers and how does that relate to heredity?

are the genetic product of their parents: on average, half of their genes/chromosomes will be like one parent, and the other half like the other. In this way, genes are passed on to the next generation.

21. As mentioned in the video, the environment can also affect an organism's traits. 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.

If gametes (sperm and egg cells) are exposed to UV light, then this may cause mutations in
