This scientist was the first person to take a picture of DNA.

What was the significant finding of Griffith's experiment?
DNA is the molecule responsible for heredity
Genetic information can be transformed from one bacteria to another
Viruses infect cells by injecting their protein coat into the cell
Why did Avery repeat Griffith's experiment?
To determine the molecule responsible for transformation
To determine how viruses infect cells
To determine how DNA replicates
Why was the Hershey-Chase experiment so important?
They were able to find a vaccine for pneumonia
The experiment supported the claim that viruses can infect bacteria cells
The experiment supported the claim that DNA was responsible for heredity
Which of the following are the three main roles of DNA? Select all that apply.
DNA stores genetic information
DNA organizes genes
DNA replicates itself
DNA puts genes to work
At the very beginning of translation, the first tRNA molecule __________.
binds to the mRNA’s start codon
connects an amino acid to its anticodon
binds to the mRNA’s anticodon
attaches directly to the DNA codon
As a result of the Hershey and Chase experiments, scientists believe that __________.
bacteriophages can be grown in culture media
viruses use bacterial DNA to reproduce
radioactive isotopes can be used safely
the “transforming principle” is DNA
A specific cell is unable to make the enzyme helicase. Because of this deficiency, what would the cell most directly be unable to accomplish?
The cell would not be able to fix mistakes in the DNA.
The cell would not be able to add the primer to the DNA strand.
The cell would not be able to add new nucleotides.
The cell would not be able to unzip the double helix.
Hershey and Chase chose to use bacteriophages in their experiments because these viruses __________.
can infect only bacteria, not humans
will not grow in radioactive culture
contain little more than DNA and protein
can be seen with a light microscope
Nucleotides that are floating free in the nucleus can then pair up with the nucleotides of the templates on each strand of the separated DNA. A group of enzymes called DNA ______________ are involved in this process.
Proteins
Polymerases
Adenines
Cytosines
An important factor in Oswald Avery’s ability to identify the "transforming principle" as DNA was the fact that proteins __________.
contain very little phosphorus
do not react with enzymes
could be observed in the extract made from R bacteria
were present in the extract made from S bacteria
During transcription, a sequence of (a) is copied onto a strand of (b) so that it can leave the (c) to find a (d) .
GAT-TAC-AGA-TTA-CAT?
ATCGTA
