Objectives
Scientists will be able to create strands of
DNA and describe the structure.
Writing and speaking: Students will recall details about DNA
and its structure.
What are we doing?
We are learning about DNA.
Why are we doing it?
We are learning about DNA because it contains
the information that determines the
characteristics of all living things.
How do I know you’ve got it?
When you can describe the structure and
function of DNA, you’ve got it!
New Vocabulary: Genes
• Repeat after me: Genes
• Dictionary Definition: the basic physical unit of heredity; a
linear sequence of nucleotides along a segment of DNA that
provides the coded instructions for synthesis of RNA, which,
when translated into protein, leads to the expression of
hereditary character.
• Our definition: A section of DNA that codes for traits
• Other forms: gene, genetic
• You try it: “Genes code for __________.”
New Vocabulary: Chromosomes
• Repeat after me: Chromosomes
• Dictionary Definition: any of several threadlike bodies,
consisting of chromatin, that carry the genes in a linear
order: the human species has 23 pairs, designated 1 to 22
in order of decreasing size and X and Y for the female and
male sex chromosomes respectively.
• Our definition: The place where all the genes of an
organisms are held.
• Other forms: chromosomes, chromosomal
DNA
• DNA (deoxyribose nucleic acid) molecules are large
and complex. They carry the genetic code that
determines the characteristics of a living thing
• Except for identical twins, each person’s DNA is
unique
• DNA can be cut up and separated, forming a sort of
“bar code” that is different from one person to the
next
• DNA is composed of 4 bases: A, C, T, G
DNA and you!
• Please read the text and answer the questions on
the next page. We will review your answers, then
watch the DNA building animation. Then, we will
build models with candy!

Let’s prove what we’ve learned!
Which of the following best describes the
purpose of the chromosomes in the nucleus
of a cell?
A. to store instructions needed to specify traits
B. to release energy by breaking down food
molecules
C. to transport nutrients into and out of the cell
D. to protect the cell from microorganisms
