Slide 3 - Quiz
What does a nucleotide look like?
Nucleotides are the monomers of nucleic acids like DNA.
They are made of three parts:
1) Nitrogenous base
2) 5-carbon (pent
ose
) sugar
3) Phosphate group
Slide 4 - Slide
DNA stands for deoxyribose nucleic acid. What part of the nucleotide is "deoxyribose?"
A
Nitrogenous base
B
Sugar
C
Phosphate group
Slide 5 - Quiz
How do nucleotides join to form DNA?
DNA is made of nucleotides joined into long strands or chains by covalent bonds.
What other molecule necessary for life is joined together by covalent bonds?
Slide 6 - Slide
Are there different types of nucleotides?
Yes!
In DNA, there are four different nitrogenous bases that make up the nucleotides. They are:
1) Adenine 2) Thymine
3) Cytosine 4) Guanine
The nucleotides pair up to create our genetic information.
Slide 7 - Slide
What does DNA have to
do with cell division?
Slide 8 - Mind map
Before cell division (like mitosis above), a cell must first replicate its DNA to ensure that each new cell gets a copy.
Slide 9 - Slide
In order to undergo replication, DNA relies on enzymes. Two important enzymes are helic
ase
& polymer
ase.
Slide 10 - Slide

A
Carbohydrates
B
Lipids
C
Proteins
D
Nucleic acids
