Essential Question
Pg 40
What are the
components of DNA?
Standard
B.6A – Identify components of DNA, and describe how information for
specifying the traits of an organism is carried in the DNA
A lesson from Jurassic Park...
There are 4 kinds of nitrogenous bases in DNA.
Adenine, Guanine, Cytosine, & Thymine
In a strand of DNA, adenine and thymine pair together while
cytosine and guanine pair together.
This pairing of bases is known as base pairing.
Hydrogen Bonds
The differently shaped bases are bonded together antiparallel
to one another (5’3’)
3’

Sage and Scribe
Can you draw a picture of
DNA using 6 nucleotides?
Watson and Crick
discovered the true
shape of DNA.
The shape of DNA is
a double helix.
A double helix looks
like a twisted ladder
or a spiral staircase.
DNA molecules in prokaryotic organisms are found in
the cytoplasm.
The DNA molecule in a prokaryotic organism is circular
in shape.
Eukaryotic organisms
possess 1000X more
DNA than prokaryotic
organisms.
Eukaryotic DNA is
generally located in the
nucleus in the form of
chromosomes.
All eukaryotic organisms
do not carry the same
number of
chromosomes.
Chromosomes are not clearly visible during most of
the cell cycle. When the DNA is “unraveled” and doing
its job, it is known as chromatin.
However, during mitosis (M phase), the chromatin coils
and condenses to form chromosomes.
Important to
Remember:
All living things have
DNA!
Scientists refer to this
as a “common genetic
code”
The sequence of bases
matters! The order
determines the
organism.
Think-Pair-Share: How do
you think DNA copies
itself?
