​Learning Targets

​LS.10.a

• I can use models to investigate the structure of DNA.

• I can describe the structure and function of DNA.

• I can discuss how the discovery of DNA, genes, chromosomes, and traits illustrate the nature of science.

Open Ended

What do you already know or want to know about DNA?

​Time for a Quick Review!

Multiple Choice

DNA is stored in the _________ of cells.

• Mitochondria

• Nucleus

• Endoplasmic Reticulum (E.R.)

​

1. ​DNA was seen in white blood cells.

2. New x-ray technology enabled scientists to "zoom in" on DNA and see it's structure​.

​Discovery of DNA

​

​New technology illustrates the nature of science because it allows scientists to make discoveries.

Multiple Choice

How does the discovery of DNA illustrate the nature of science?

• Scientists used new technology to make the discovery.

• Scientists discovered DNA a long time ago.

• ​Spiral shape = double helix

• Two-sided​

• Made of nucleotides

  • ​Adenine, Thymine, Cytosine, and Guanine

​​DNA Structure

​

• ​DNA = chemical instructions for making proteins

  • Proteins determine your traits!​

​​DNA Function

​

​Let's Zoom IN!

​Some text here about the topic of discussion.

​Nucleotides

​

• Base pairs = 2 nucleotide​s

  • ​Adenine (A) can only pair with Thymine (T)

  • Guanine (G) can only pair with Cytosine (C)

Multiple Choice

A, G, T, and C are all ______________.

• Organelles

• Nucleotides

Match

Match the following base pairs.

• A

• G

• T

T

C

A

• T

• C

• A

​Let's Zoom OUT!

• ​specific base pairs in a specific order

• code that tells proteins what traits to give you

​Genes

​

= Height Gene

​

​Example

​

ATCG/TAGC = Tall

Multiple Choice

Each section of DNA that codes for a specific trait is called a _______.

• gene

• DNA

• base pair

Poll

How are you feeling about understanding the structure of DNA?

• Really good. It makes sense.

• Okay. I know I will get better.

• Meh. Some of it is still confusing.

• Terrible. None of this makes sense.
