(Mostly) History of DNA
Which scientist used xray crystalography to determine the shape of DNA?
Rosalind Franklin
Why is the lagging strand slower to copy?
DNA polymerase does not directly follow helicase, and therefore, has to keep going back to copy multiple segments.
Where were French fries invented?
Belgium
What is the name of the enzyme that goes back through and seals the broken strands back together?
Ligase
The two directions of the DNA strands.
5' to 3' and 3' to 5'
What is it called when DNA loses its shape due to heat and the two strands separate from each other?
dentauring
What is Chargaff's Law?
The amount of Adenine is equal to the amount of Thymine.
The amount of Cytosine is equal to the amount of guanine
Before DNA can be synthesized, a short sequence of this must be placed on the template strand.
RNA Primer placed by primase.
What is the chemical process responsible for building polymers?
dehydration synthesis
Who won the Nobel prize for discovering DNA?
Watson and Crick
The enzyme that relieves tension from supercoiling.
What is topoisomerase?
The phase of the cell cycle that DNA replicates itself during.
What is S-phase? (Synthesis)

If there is 30% guanine in a cell, how much thymine is present?

What is the difference between DNA Pol I and III?
Pol III - primary replication enzyme
