100
They discovered that DNA
was the genetic material.
200
Answer
Who were Hershey and Chase?
200
100 pt bonus- how did they do this?
Labeled DNA with Radioactive
Phosphorus, then looked to see
where the phosphorus was
Watson and Crick did this.
300

What is helicase?
100
100pt bonus: What molecule keeps
the strands apart?
Single-strand binding proteins
This molecule joins
short strands of DNA.
200
Answer
What is ligase?
200
DNA polymerase does this.
Answer
What is add nucleotides to the new
strand during replication?
300
This molecule makes short sections of
RNA to start transcription.
400
Answer
What is DNA Polymerase I?
400
The section of mRNA removed
after transcription.
100
Answer
What are introns?
100
The type of cell that
has both chromosomes
from the homologous pair.
200
Answer
What is a diploid cell?
200
The three useless cells
made in egg cell meiosis.
300
Answer
What are polar bodies?
300
100 pt Bonus: What is it called?
The process in meiosis that splits
up the homologous pair.
400
Answer
What is meiosis I?
400
The three nucleotides found on
a molecule of tRNA.
100
Answer
What is an anticodon?
100
Transcription takes place here.
200
Answer

200
What “DNA” and “RNA”
are named for.
300
Answer
What are the sugars?
300
A point mutation that
causes no problems.

DNA much larger
Single strand vs double helix
200
The molecule that ribosomes
bind to in translation.
400
Answer
What is mRNA?
400
This molecule that transfers
amino acids to the ribosomes
600
Answer
What is tRNA?
600
This enzyme (catalyst) helps
transcription occur in the nucleus.
800
Answer
What is RNA polymerase?
800
This was determined to be the
cause of transformation by Griffith
in his experiments with mice
200
Answer
What is DNA (moving
from one strand to another)?
200
He determined that the amount of
adenine = thymine and
cytosine = guanine.
400
Answer
Who is Erwin Chargaff?
400
Avery, McLeod, and McCarthy purified
Various chemicals in bacteria and
Supported this claim of Griffith’s.
600
Answer
What is DNA as the
transforming property
(Genetic material).
600
Meselson and Stahl proposed this
Theory stating that each strand of
DNA created during replication in part
new strand and part original.
800
Answer
What is the semiconservative
model of replication?
800
The ingredients needed for a PCR.
200
Answer
What are heat, nucleotides, DNA,
DNA polymerase, and primers?
200
Molecules that cut DNA in specific
places, giving sticky ends.
400
Answer
What are restriction enzymes?
400
An agent used to transfer DNA
from a solution to a living cell
(i.e. a plasmid).
600
Answer
What is a vector?
600
The number of restriction enzymes
used in genetic recombination and why.
800
Answer
What are 1 because it cuts in
the same spot and creates
the same sticky ends
800
An addition or subtraction of
a nucleotide that causes the
remaining nucleotides to
shift up or down.
200
Answer
