Scientists
The scientist who discovered there was a "transforming agent" through his experiment with mice.
Griffith
The name given to the shape of DNA by Watson and Crick
double helix
The copying of DNA
DNA Replication
What is the function of an enzyme
Speed up a chemical reaction
The name of the area where DNA begins to replicate/copy/divide
replication fork
The scientist who discovered that A=T and C=G.
Chargaff
DNA stands for
deoxyribonucleic acid
This is where DNA replication begins, often at hundreds of sites at a time.
Replication fork
This enzyme is responsible for unzipping DNA
Helicase
Which of the 4 nitrogenous bases pair
A-T
C-G
Discovered that viruses infect cells with DNA- NOT protein., using a bacteriophage
Hershey and Chase
These are the four nitrogen bases.
Adenine, Thymine, Cytosine and Guanine
The DNA is circular and located in the cytoplasm
Prokaryotes
What is the role of telomerase
lengthen chromosome by adding short, repeated DNA sequences to telomeres
The complimentary strand to a template DNA strand that reads "CAT TAC GCT"
What is "GTA ATG CGA"?
Rosalind Franklin used this technique to determine that there are two stands in a DNA molecule.
X-ray diffraction
What are the three components of a nucleotide
5-carbon sugar, phosphate group, and nitrogenous base
This cell's DNA is in the nucleus
Eukaryotes
Where is a telomere
At the tips of chromosomes
term that describes DNA running in different directions
antiparallel
This scientist used enzymes to break down certain molecules and discovered which molecule as the transforming factor.
Avery, DNA
These are the bonds that hold the sides of the ladder together and the rungs of the ladder together
Covalent bonds, hydrogen bonds
Why is DNA considered semiconservative
The old strand is conserved as a template to build a new strand of DNA
What is the role of DNA Polymerase
add free nucleotides and proofread DNA for errors
If the percentages of Adenine is 20, what is the percentage Guanine?
30
