Total questions: 10
Worksheet time: 5mins
What is the first thing that DNA has to do before it can be replicated?
Get tightly wound
Get unzipped by helicase
Nothing, it is ready to go
Get unzipped by DNA Polymerase
What does DNA Polymerase do during DNA replication?
Adds new nucleotides according to the base pairing rules
Adds new nucleotides that are identical to the strand
Adds new sugars and phosphates only
Splits apart the DNA so that helicase can continue adding bases
What are the 3 components of a Nucleotide in DNA?
Deoxyribose Sugar
Ribose Sugar
Phosphate Group
Nitrogenous Base
What holds the 2 strands of DNA together?
Nitrogen Bonds
Oxygen Bonds
Carbon Bonds
Hydrogen Bonds
Why is DNA replication considered semi-conservative?
Because each new molecule of DNA has 2 new strands
Because each new molecule of DNA has 2 old strands
Because each new molecule of DNA has one old and one new strand
Because each new molecule is only halfway completed

AG and CT
AT and GC
AU and GC
AG and UC
