100
These people suggested that DNA serves as a template for its own replication.
Who are Watson and Crick?
100
This type of replication involves the division of a single strand of DNA into smaller parts to be transferred to another strand during replication.
What is Dispersive replication?
100
This type of bacteria was used in Meselson and Stahl's experiment.
What is Escherichia coli?
100
The results supported this model of replication.
What is Semiconservative?
100
The number of years after Watson and Crick's discovery that this experiment was performed.
What is 5 years?
200
This person discovered the rules of base pairing that allow for semiconservative replication.
Who is Chargaff?
200
This type of replication results in no hybrid DNAs after replication.
What is Conservative Replication?
200
This isotope of nitrogen used in their experiment is heavier and was used in the first phase of their experiment.
What is Nitrogen 15?
200
The experiment helped to explain how these lead to inherited genetic disorders.
What are mutations?
200
The first name of Messelson and the first name of Stahl.
What are Matthew and Franklin?
300
In this year and at this location Meselson and Stahl performed their life-altering experiment.
What is 1958 at California Institute of Technology?
300
In this type of replication, Meselson and Stahl attempted to prove its accuracy through showing that DNA is unzipped during replication to form two new double strands.
What is Semiconservative Replication?
300
This is the solution that the DNA was placed in for density gradient centrifugation.
What is Cesium Chloride (CsCl)?
300
The proof of Semiconservative replication was evident when most of this DNA was found in the middle and upper portion of the cesium chloride solution.
What is the less dense DNA containing N14?
400
Meselson and Stahl invented this method of separating DNA based on it weight.
What is density gradient centrifugation?
400
In this type of replication, their experiment showed an increasing ratio of N14 strands to N15 strands when in the N14 solution as an increase amount of replications occurred.
What is Semiconservative Replication?
400
The method used to separate and compare the different DNA samples.
What is Density gradient centrifugation?
400
Because the DNA fell to this position in the gradient, it could be determined that both strands of DNA contained the N15 isotope.
What is the bottom of the gradient?
400
This is the form in which the N15 was contained in.
What is ammonium chloride (NH4Cl)?
500
These make up a molecule of DNA.
What are a nitrogenous base, a five carbon sugar (deoxyribose), and a phosphate group?
500
This form of replication results in two new strands of DNA that do not form independently of one another.
What is Conservative Replication?
500
This level of density of most of the final strands of DNA produced showed these DNA strands in the upper portion of the cesium chloride solution.
What is low density?
500
When the bacteria were first moved from the N15 solution to the N14 solution, the newly replicated DNA moved to this part of the entity gradient.
What is the middle of the gradient?
