DNA Model Questions (Daisha & Tyler)
DNA is short for Deoxyribonucleic acid. DNA is a molecule that contains the instructions an organism needs to develop and to reproduce. DNA is also an double Helix.
2. What are the building blocks of DNA called? Name the three main components of these building blocks.
The 4 main components of the building blocks of DNA are Adenine (A), Cytosine (C), Guanine (G) and Thymine (T).
3. Where in the eukaryotic cell is the DNA found?
In the eukaryotic cell DNA is found in the nucleus, the mitochondria, and the chloroplasts
4. List and describe as many functions of DNA in living things that you can think of (at least three!)
The main function/ role of DNA is the storage of information.
5. List each color that is represented for the nitrogenous bases located within the center of the molecule.
Blue, Grey, Red and Green
6. Examine the nucleotides. Draw and take a picture of a nucleotide and lable the three parts.
A glycosidic bond forms between a nitrogen base group.
8. What type of bonds form between the sugar- phosphate groups?
A covalent bond forms between the sugar- phosphate groups.

DNA MODEL (London)
•DNA is ones genetic information.
• The main 3 components in the model are the sugars the phosphates and the nitrogenous bases.
• DNA is found inside the nucleus of a cell.
•Grey
Green
Blue
Red
•
•hydrogen bonds form between the nitrogenous bases and they are weak so they are able to break apart
DNA Model Questions(your name here)
Answer
the following questions and post your DNA pictures and for this blog.
1.
What
is DNA?
2.
What
are the building blocks of DNA called? Name the three main components of these
building blocks.
3.
Where
in a eukaryotic cell is DNA found?
4.
List
and describe as many functions of DNA in living things that you can think of
(at least three!)
5. List each color that is represented for the nitrogenous bases located within the center of the molecule.
6. Examine
the nucleotides. Draw and take a picture of a nucleotide and label the three parts. Use your textbook
or Google images if you need help.
7. What
type of bonds form between the nitrogen base pairs? (Look it up if nobody in
the group knows.)
8. What type of bonds
form between the sugar-phosphate groups
1.
If a DNA molecule were
composed of 10% guanine, what percents of the molecule would be made up of
cytosine, adenine, and thymine? Show your work.
