the process of duplicating DNA
What is replication?
100
double helix
What is the shape of a DNA molecule?
100
store - copy - transmit
What are the 3 things DNA must is able to do?
100
DNA is found in the cytoplasm in this type of cell
Where is DNA found in a Prokaryote?
100
a virus that infects bacteria
What is a bacteriophage?
200
DNA polymerase
What is the enzyme that bonds nucleotides together in replication?
200
nucleotide
What is the subunit called that makes up a DNA molecule?
200
transformation
What is the process in which one strain of bacteria is changed by DNA from another strain of bacteria?
200
Transcription takes place in the nucleus and translation takes place in the cytoplasm in this type of cell
What is Eukaryote?
200
he discovered the process of transformation
Who is Griffith?
300
Area where the DNA has been split by an enzyme
What is a replication fork?
300
5 carbon sugar (deoxyribose) - phosphate group - nitrogenous base
What are the three parts of a nucleotide?
300
to allow DNA to separate during replication and transcription
What is the reason for weak hydrogen bonding between nitrogen bases in DNA?
300
the % of A=T and the % of G=C
What is Chargaff's Rule?
300
he discovered that DNA is the substance that causes transformation.
Who is Avery?
400
strands separate - base pairing - nucleotides joined together
What are the steps of DNA replication?
400
weak hydrogen bonds
What is holding the two sides of DNA together?
400
contain instructions for assembling proteins (be specific)
What are genes?
400
Franklin
Who took x-ray defraction pictures of DNA structure?
400
used radioactive labels to determine that is was DNA passed on by bacteriophage.
What is the Hershey Chase experiment?
500
the nucleus
Where does replication take place?
500
adenine paired with thymine / guanine paired with cytosine
What is base pairing?
500
G- C- A- T- C- A-
What is C-G-T-A-G-T
500
Watson and Crick
Who figured out the structure of DNA with a model?
500
live, harmless bacteria mixed with heat-killed disease-causing bacteria
What caused a new discovery in Griffith's experiment when the mice died?
