Genetics
Today I will define
and recognize
genes, DNA, and
chromosomes
•Chromosomes, DNA, Genes,
and Traits are genetic material
found in the nucleus of the cell
Genes are segments of Chromosomes
A gene is a section of DNA that
controls a trait ( ex. tall /short) that an
organism inherits
TPS: if genes are sections
of DNA, where are genes
located in the cell?

What do you know about
DNA?
Where have you
heard the term?
What was the context
or situation?
DNA
Write this in your
notebook and be
ready to share with
your class as your
teacher records on
the board.

• Because DNA is a nonliving, nonreactive chemical molecule…
• It can be recovered from mummies over 2000 years old.
• DNA is found in dried blood in murder investigations
• DNA can be found in ancient bones
7
• The genetic material that
carries information about an
organism passed from parent
to offspring
• DNA is a complete set of
instructions necessary to make
and maintain the human body.
• DNA is a blueprint of the
human body

Where is
DNA?
Found in Cells…
inside the
Nucleus , the
Control Center.
DNA is wound
tightly into
structures called
Chromosomes so
it can fit into a tiny
cell…
so,
Chromosomes are
made of DNA
Short sections of
DNA are called
Genes
10
• Chromosomes are DNA
wrapped around
proteins to form an Xshaped structure.
• Chromosomes are
located in the nucleus of
a cell
• A chromosome is formed
from a single DNA
molecule that contains
many genes.
