Section 1
Griffith was working with a bacteria that caused which disease?
Pneumonia
What is the basic unit that makes up DNA called?
Nucleotide
Copying process by which a cell duplicates its DNA.
Replication
Found that harmless bacteria, mixed with heat-killed harmful bacteria will transform and kill a mouse
Griffith
This scientist was the one to determine that in any sample of DNA, A=T and C=G.
Chargaff
The process in which one strain of bacteria is changed by a gene or genes from another strain of bacteria.
Transformation
What are the 3 parts of a nucleotide?
Sugar, phosphate, base
Enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule?
DNA polymerase
Repeated experiments with mice and pneumonia to officially determine that DNA was the transforming factor
Avery
How did Rosalind Franklin photograph DNA?
Using X-ray diffraction
When Griffith took the heat-killed harmful bacteria and mixed it with the harmless bacteria and gave it to the mouse, what happened to the mouse?
It Died
What do we call the shape of DNA?
Double Helix
In eukaryotes, where is the DNA located?
In the nucleus.
Worked with bacteriophages and radioactive markers to show that DNA is injected into bacteria cells
Hershey and Chase
What are the three things that DNA must be able to do?
Store, copy, and transmit information.
What did Avery determine was the transforming factor in his experiments?
DNA
What type of bond holds the bases in DNA together?
Hydrogen bonds
For the following strand of DNA, give me the matching strand: AATGCGCTA
TTACGCGAT
Created the first model of DNA structure from cardboard and wire.
Watson and Crick
Which two parts of a nucleotide make up the backbone of DNA?
Sugar and phosphate
What do you call a virus that infects bacteria?
Bacteriophage
What is the principle that bonds can only form between the bases A-T and C-G called?
Base Pairing
What is the first step in DNA replication?
Separate the DNA molecule into two strands.
Took pictures which helped to give scientists clues about the structure of DNA.
Franklin
Bases can be put into two categories: Purines and ___________.
Pyrimidines
