DNA (deoxyribonucleic acid)
• the master copy of an organism’s information
code that contains the instructions used to
form all of an organism’s enzymes and
structural proteins.
Deoxyribose sugar
• The sugar found in the side chains of DNA and
has 5 sides.
Phosphate group
• a phosphorous atom with 4 covalently
attached oxygen atoms, which bonds to
deoxyribose sugar in DNA.
Nucleotide
• Subunits of nucleic acid formed from a
deoxyribose sugar, a phosphate group, and
nitrogenous base.
Nitrogenous base
• Carbon ring structure found in DNA and RNA
that contains one or more atoms of nitrogen
– Adenine
– Guanine
– Cytosine
– Thymine (found in DNA only)
– Uracil (found in RNA only)
Base pair
• To form the DNA molecule, bases pair
together across the double helix structure.
Adenine (A) always pairs with Thymine (T),
and Cytosine (C) always pairs with Guanine
(G). These are the only pairs possible.
Amino Acid
• Basic building blocks of protein molecules
