DNA Experiment for Parents!!!
• Tonight, I want you to attempt to extract
DNA from different types of food in your
home.
• You are to discuss and explain this process
to your parents.
Review/Explain:
Types of Nucleic Acids
What are the two types of
nuclei acids?
Ribonucleic Acid
(RNA) – Single Stranded
Deoxyribonucleic Acid
(DNA)
• Double Helix
– (Twisted Ladder)
DNA
• Deoxyribose Sugar
• Base Pairs
A-T
G-C
• Phosphate
• Most Importantly--– Contains the Code for ALL the Proteins in the Body
RNA
•
Ribonucleic Acid
(RNA)
•
•
Sugar + Phosphate Backbone
Differs from DNA
– Single Stranded
– Ribose Sugar
– Base Pairs A-U, G-C
–
–
•
Are there T’s in RNA?
A, U no T’s in RNA
RNA assists DNA in
manufacturing needed proteins
Questions
• Name one difference between DNA and
RNA.
– DNA – Double Helix, RNA – Single Stranded
– DNA --- A-T, RNA ---A-U
– DNA ---Deoxyribose Sugar, RNA---Ribose
• What is a similarity of DNA and RNA?
– G binds with C in both DNA and RNA
– Both have sugar and phosphate backbone
Getting The Letters Out
Practice
• On your paper, complete the missing DNA strand
by adding the complementary bases.
• AT C GTT G C CAT C
• TA G C AA C G G TA G
• Make the complementary RNA strand for the
single strand of DNA below:
• AAT C AT C A C G T T
• U U A G U A G U G C AA

–
Cytosine
Adenine
Guanine
Thymine
Phosphate
Deoxyribose
DNA to RNA
• Using your DNA model and notes, what
changes would you have to make in order to
change this into an RNA molecule?
DNA
• What is the Main Job of DNA?
• It contains the code for the proteins an organism
may produce.
• What are the basic units or monomers of DNA?
• Nucleotides make up DNA.
• Where is DNA found?
• It is found mostly in the nucleus of a cell making
up its chromosomes.
RNA
• What is the Main Job of RNA?
• It retrieves the protein code from DNA and carry
out the processes needed to produce proteins.
• What are the basic units or monomers of DNA?
• Nucleotides
• Where is RNA found?
• It is found both inside and outside of the nucleus.
