1. Nucleic Acids
GT Biology 

2. Nucleic acids are composed of:
A. Carbon
B. Hydrogen
C. Oxygen
D. Nitrogen
E. Phosphorous

3. II. Two kinds of nucleic acids
DNA – DeoxyriboNucleic Acid
B. RNA – RiboNucleic Acid
RNA
DNA

4. III. Structure of Nucleic Acids
Formed of repeating units called nucleotides which are made of:
1. a 5 Carbon sugar
2. a Phosphate group
3. One nitrogen base A
5 carbon
sugar
Nitrogen base
phosphate

5. The 5 carbon sugar
1. DNA has Deoxyribose
2. RNA has Ribose

6. The Nitrogenous bases
1. Adenine (A)
2. Cytosine (C)
3. Guanine (G)
4. Thymine (T) – only in DNA
5. Uracil (U) – only in RNA
The bases pair up to form the center of the DNA ladder.
in DNA: A-T C-G
in RNA: A-U C-G

7. C A G T

8. D. The Phosphate group
Phosphate groups attach the “sides”
of the DNA and RNA ladder…
alternating sugar and phosphate.

9. Sugar
Bases
Phosphate

10. How many nucleotides are in this entire section of DNA?
One nucleotide

11. IV.Differences between DNA and RNA
DNA RNA
* thymine * uracil
*double helix *single stranded
*found in the *throughout the cell
nucleus, made made in the
here nucleolus
*Deoxyribose *Ribose

14. Function
1. DNA makes up your genes that
direct the creation of RNA &
proteins
2. RNA helps create proteins

15. Create a Venn diagram comparing and
Journal Entry
Create a Venn diagram comparing and
contrasting the nucleic acids DNA and
RNA.
just RNA
both
Just DNA
