DNA REVIEW
The connecting pieces or
“rungs” on a DNA ladder.
NITROGEN BASES
Structure in the cell where
chromosomes are located.
NUCLEUS
The copying of a DNA
molecule.
REPLICATION
The other substance in
addition to phosphates that
make up the “handrails” of
the DNA ladder.
SUGAR
A section of DNA
controlling the making of
specific proteins.
GENE
Scientist who used X-ray
diffraction to determine
that DNA was a helix.
ROSALIND FRANKLIN
Heredity structures made
up of DNA and protein.
CHROMOSOMES
Substances that determine
our physical appearance.
PROTEINS
Scientist who worked with
James Watson in
developing the doublehelix model of DNA.
FRANCIS CRICK
The structure of a DNA
molecule.
DOUBLE HELIX
An organism’s
informational code.
DNA
Nitrogen base always
paired with adenine.
THYMINE
Nitrogen base always
paired with guanine.
CYTOSINE
An abnormality or
deformation of an
organism due to pollutants
in the environment that
affect the organism’s DNA.
MUTATION
Repeating units of a sugar,
phosphate, and a nitrogen
base that create the DNA
helix.
NUCLEOTIDE
A chemical used to read
the DNA in the nucleus
which takes the message
to the ribosomes where
proteins are made.
mRNA
Base that replaces thymine
in messenger RNA (mRNA).
URACIL
Besides viewing this slide
show again . . . And again .
. . And again, what else can
you do to prepare for the
quiz?
• Look over the handouts in your
notebook focusing on the BOLD
FACED words.
• Review the “What is DNA?” slide
show on my teacher webpage.
