The 4th type of biochemical macromolecule is NUCLEIC ACIDS

The 2 nucleic acids we will be studying are…

Nucleic AcidsNucleic Acids

What they do for living things

Nucleic Acids1) DNA

• Is our genetic material. Chromosomes are made of DNA.

• Chromosomes contain the “recipes” to make proteins for your body.

3) RNA• Reads the DNA “protein recipes” and makes the

proteins for your body.

ElementsMonomer

Shapes

The elements found in Nucleic Acids are

CarbonHydrogenOxygen

Nitrogen Phosphorus

You can remember it by the word You can remember it by the word ““CHNOPCHNOP””

DNA has a double DNA has a double helix shape helix shape

RNA has a single RNA has a single Helix shapeHelix shape

The shape of Nucleic Acids

If you picture DNA as being a spiral staircase, the nitrogen

bases would be the steps.

Monomers of Nucleic Acidsare called nitrogen bases.

This is PrOOf that humans arose from alien DNA !

The amount of energy gained by eating nucleic acids…

Nucleic acidsThe nucleic acids in food are not

considered a substance that the body uses to gain energy.

So, you won’t find nucleic acids listed on a

nutrition label!

Final Review QuestionsPlease do not look back at the information in your handout.

1. What are the names of the 2 types of nucleic acids?

2. What elements are found in nucleic acids?

3. What does DNA do? RNA?

4. What are the monomers of nucleic acids?

5. How many Calories are found in 1 gram of nucleic acids?

You are Finished!

YaHoOoOoOo!
