 DNA = Makes up genes for all living things.
 What are genes??
◦ Blueprints for us!!
 Genes are parts of DNA that code for
particular traits or proteins.
 Deoxyribonucleic
Acid (DNA)
 Dee-oxy-ribo + nuke-lay-ick +Acid
 “Double Helix”
shape
1.Number of strands
It doesn’t have hydroxyl group at the 2’ position. It just
has a hydrogen, thus deoxygenated.
DEOXYRIBOSE
2.SUGAR
3. Location
 Four
bases are:
◦ Thymine
◦ Adenine
◦ Cytosine
◦ Guanine
4. Nitrogenous bases
 Protein Synthesis
 Mainly helps in the expression of the genes
that DNA encodes by allowing the DNA to be
interpreted and code for various proteins
