Who discovered the shape of
the DNA molecule and won the
Nobel Prize?
Watson & Crick
Scientists - 100
Who used X-rays to determine
what DNA really looked like?
Rosalind Franklin
Scientists - 200
What scientist actually found DNA is the
“factor” that caused good bacteria to
change into bad bacteria? He also used
mice in his experiment.
Avery
Remember: Avery got an
“A” for finding DNA
Scientists - 300
Who used radioactive
bacteriophages (viruses) to find
the genetic material?
Hershey & Chase
They “chase”d after Avery’s idea
of where genetic material is found
using viruses.
Scientists - 400
Who tried to find the genetic
material but failed? Instead he
found TRANSFORMATION.
This scientist
injected mice with
killed disease
causing bacteria
and good, live
bacteria and the
mice died of
pneumonia.
Griffith
F for failing to find genetic material!
F for finding

What does DNA stand for and
what is its shape?
DeoxyriboNucleic Acid
Double Helix
DNA #1 - 100
What sugar is in DNA?
Think: “ose”
Deoxyribose
(Do not need to know
this structure. )
DNA #1 - 200
Name the 3 parts of a DNA
nucleotide
5-Carbon Sugar
(Deoxyribose)
Phosphate Group
Nitrogen Base
DNA #1 - 300
Name the 4 Nitrogen bases in DNA and
how do they pair up?
What is the
rule called and
what scientist
found it?
What holds
pairs together?
Adenine (A)=Thymine (T)
Cytosine (C)=Guanine (G)
Rule of Base Pairing
or
Chargaff’s Rule
Hydrogen Bonds
DNA #1 - 400
What are the structures of A&G
and T&C called?
Double ring
Single ring
Are there more purines
or pyrimidines in DNA?
Purines (A&G) 2 rings (house &
outhouse)
DNA #1 - 500
Pyrimidines (T&C) 1 ring
cytosine & thymine
%Purines = %Pyrimidines
What is the name of the protein
that DNA wraps itself around to
condense (coil up)?
Histones
DNA #2 - 100
1. What is replication?
2. Why is it important?
3. How many new strands are
made at the end of replication?
1. Copying of DNA
2. For cell division
3. 2 new strands of DNA
giving a total of 4 strands
1 new w/ 1 original
DNA #2 - 200
An original strand of DNA has
these nitrogen bases
CGGTATGAC
What are the bases for the new
DNA strand during replication?
C G G T A T G A C original
G C CATAC TA
new
DNA #2 - 300
What enzyme (protein) copies the
DNA for replication?
DNA Polymerase
DNA #2 - 400
Where is DNA found, what
type of cells, and what is its
function?
DNA is the genetic code for
making proteins and is found in
the nucleus of eukaryotes.
DNA #2 - 500
What does RNA stand for and
what is its function?
RiboNucleic Acid
Makes proteins
RNA #1 - 100
What sugar is in RNA?
Ribose
RNA #1 - 200
What nitrogen base does RNA
have that DNA does not have?
Uracil (Hint: r for RNA)
RNA #1 - 300
What is the structure of RNA and
where is it found?
Single Strand
starts in nucleus and goes out to
cytoplasm to the ribosome.
RNA #1 - 400
CYTOPLASM
Name some
similarities
between DNA
and RNA?
Both Have:
Sugar + Phosphate
Backbone
A, C, G nitrogen bases
RNA #1 - 500
What is the enzyme (protein) that
reads the DNA and makes mRNA?
RNA Polymerase
RNA #2 - 100
What is the 3 base code on the
mRNA called?
Codon
RNA #2 - 200
Name the 3 different types of RNA
and what do each do.
mRNA- brings genetic code for proteins
from DNA to ribosome
(recipe)
tRNA- brings amino acids to ribosomes
(sous chef)
rRNA- (ribosome) makes the protein (chef)
RNA #2 - 300
Where does the mRNA go after
being made in the nucleus?
Name the location in the cell and
organelle.
To the ribosomes in the cytoplasm
RNA #2 - 400
What does the tRNA bring to the
ribosome, how many, and what
are the 3 bases called?
(Need 3 things)
tRNA
brings
1 Amino Acid
and attaches to codon
using its
Anticodon
