DNA Replication & Enzymes
This enzyme unzips DNA by breaking the hydrogen bonds between nitrogen bases.
What is helicase?
This part of a nucleotide contains the genetic information using the letters A, T, C, and G.
What is the nitrogenous base?

If the original DNA sequence is A-T-G-C, what is the complementary sequence?
What is T-A-C-G?
What enzyme patches in fragments of DNA by connecting phosphate and the sugar backbone?? (The glue guy)
Ligase
This enzyme creates short RNA primers that allow DNA polymerase to begin building.
What is primase?
If an organism has 56 chromosomes in its body cells, how many came from each parent?
What are 28 chromosomes from each parent?
This strand is built in short sections called Okazaki fragments.
What is the lagging strand?
What famous military ruler crossed the Alps with elephants, was exiled to the island of Elba, escaped, returned to power for 100 days, and was finally defeated at Waterloo?
Napoleon Bonaparte
Loosely packed DNA that is rapped around histones. It is easily accessible and the form DNA is normally in.
Chromatinnnnnn
This enzyme connects Okazaki fragments on the lagging strand.
What is DNA ligase?
Play-by-Play radio announcer for Husker Volleyball
What 2 pieces of information do you need to determine what the leading and lagging strand are???
Direction of helicase
Which way the "primes" are facing
DNA replication must happen before this process.
What is cell division?
Why is DNA considered to be "semi-conservative"?
This enzyme relieves tension ahead of the replication fork and prevents DNA from becoming too tightly twisted.
What is topoisomerase?
Phosphate and ribose sugar.... covalent bond
Why does the lagging strand need to be built in fragments instead of continuously?
What is because DNA polymerase can only build in the 5' to 3' direction, which means the lagging strand is built away from the direction the replication fork is opening?
Why must DNA replicate before a cell divides?
What is so each daughter cell receives a complete copy of the genetic instructions?

DNA polymerase READS the original template strand in this direction but builds the new strand in the opposite direction.
What is 3' to 5' for reading and 5' to 3' for building?
Explain the difference between a gene, a chromosome, and a trait.
What is a gene being a section of DNA, a chromosome being a tightly packaged structure of DNA containing many genes, and a trait being a physical characteristic?
This strand is built continuously as the replication fork opens.
What is the leading strand?
What is the term we use for all of the DNA contained inside of an organism.
When do you call the Ghost Busters?
When there is something strange in your neighborhood...
