DNA Structure
This is the name for a virus that infects bacteria, specifically E. coli.
What is T2 Bacteriophage?
These are the 3 things that make up a nucleotide.
What are bases, sugars and phosphate groups?
This enzyme unwinds DNA during replication and breaks the H bonds between nucleotide bases.
What is DNA helices?
This is the starting segment of nucleotides to the leading strand.
What are RNA primers?
These guys created the accurate DNA model.
Who are Watson & Crick?
Hershey & Chase showed in their experiment that this was a transformation agent.
What is DNA?
Adenine pairs with....
Cytosine pairs with.....
What is thymine? What is guanine?
This is the starting point for DNA replication on the DNA strand.
What is the origin of replication?
These keep 2 strands apart and from bonding back together.
What are single stranded binding proteins?
This scientist performed X-ray crystallography and created a "photograph" of DNA
Who is Rosalind Franklin?
In a ladder analogy, what does the sugar phosphate backbone represent?
What is the sides of the ladder?
In the ladder analogy, what does the nitrogen bases represent?
What are the rungs of the ladder?
This is when one original strand of DNA serves as a template to make a new strand of DNA.
What is a semi-conservative model?
This is the direction that DNA strands are read in.
What is 5' to 3'?
What is hydrogen bonding between complementary nitrogenous base pairs?
Adenine and Guanine are these kind of bases.
What are purines?
Cytosine and thymine and uracil are these kind of bases.
What are pyrimidines?
This is the phase of the cell cycle that DNA replication occurs at.
What is the S phase?
What is G2 phase?
This enzyme joins Okazaki fragments together.
What is ligase?
In a DNA molecule, there is 35% G. This is the percentage of T, A and C in the same DNA molecule.
What is 15% T, 15% A, 35% C?
If a DNA molecule is made up of 17% Guanine, this is how much adenine, thymine and cytosine in the molecule.
What is 17% cytosine, 33% thymine, 33% adenine?
What is proofreading and elongation / addition of new nucleotides?
These are the 3 steps of nucleotide excision repair.
What is removing pairs, replacing the missing nucleotides and stitching back together the fragments?
These are the 2 locations where DNA is located.
What are the nucleus and mitochondria?
