Information Storage and Energy Transfer
Nucleic Acid Basics
 Made of C,H,O,N,P
SPONCH
 Monomer is a nucleotide
 Functions
- information storage
- information transfer
- energy transfer
Meet the Monomer-Nucleotide
P = Phosphate Group
S= 5 Carbon Sugar (ribose or deoxyribose)
B= Nitrogen Base
Meet the Polymer
 Polymers of nucleic acids are chains of nucleotides
joined by condensation reactions
 They are held together by covalent bonds between the
sugar of one nucleotide and the phosphate of another
- called phosphodiester bonds
Meet the Polymers
 DNA 2 chains of
nucleotides held
together by H Bonds
RNA
Nucleic Acid Types-DNA
 Deoxyribonucleic Acid
 made of two strands of
nucleotides
 Form a double helix
 DNA stores hereditary
information
- recipes for the proteins
 found in the cell’s
nucleus
Nucleic Acid Types- RNA

Ribonucleic Acid
 Single strand of
nucleotides
 forms a single helix
 transfers information from
the DNA to the ribosomes
- carries a protein recipe to
the ribosome
-ribosomes are structures in a
cell that make protein
DNA- stores protein recipes in the nucleus
RNA – transfers them to the ribosome to be built
DNA vs. RNA
 Double stranded
Single Stranded
 Sugar–Deoxyribose
Sugar – ribose
 Nitrogen Bases
Nitrogen Bases
Adenine
Uracil
Guanine
Cytosine
Adenine
Thymine
Guanine
Cytosine
Nucleic Acid Types - ATP
 Adenosine Tri-Phosphate
 ATP is a single nucleotide
 high energy molecule
 produced by cellular
respiration
 transfers energy within
cells
DNA/RNA vs. ATP
DNA or RNA
ATP
Nucleic Acid Types-ADP
 Adenosine Di-Phosphate
 Single nucleotide
 “rechargeable” energy
transfer molecule
 Lower energy than ATP
 Cellular respiration converts
ADP into ATP
