Enzymes
This is the enzyme that "unzips the genes" by breaking the weak hydrogen bonds.
What is helicase?
This is the word for the shape of DNA
What is a double-helix?
Early scientists thought this was the likely genetic material due to its complexity.
What are proteins?
DNA is copies during this part of interphase.
What is the S phase?
The name of the area where DNA begins to replicate/copy/divide
What is the origin of replication?
This enzyme adds the new nucleotides during DNA replication?
What is DNA Polymerase?
These 2 men are credited with discovering the structure of DNA.Step 2
Who are Watson and Crick?
The "Y-shaped" region on DNA where the 2 strands of DNA separate during replication.
What is the replication fork?
This is the enzyme that links the okazhaki fragments together after primers are removed.
What is DNA Ligase?
She was responsible for the X-ray crystallography photographs that helped Watson and Crick with their elucidation of the structure of DNA.
Who is Rosalind Franklin?
This strand of DNA during replication is synthesized as a single strand from the point of origin toward the opening replication fork.
What is the leading strand?
The complementary DNA strand for the following DNA sequence: 5’-CGTATG-3’
What is 3’-GCATAC-5’ ?
This person has a rule named after him for figuring out the relative abundance and pairing rules for the four nitrogenous bases in DNA
Who is Chargaff?
The series of short segments on the lagging strand of DNA during DNA replication.
What are Okazaki fragments?
The enzyme that synthesizes the RNA Primer.
What is RNA primase?
The experiments done by these biologists used bacteriophage and radioactivity to support the idea that DNA is the genetic material.
Who is Hershey and Chase?
DNA replication is referred to as this because the two strands of the parental molecule separate, and each acts as a template for a new complementary strand.
What is semi-conservative?
