What is the process of cell division called?
Mitosis
When does DNA replication occur?
S phase
What is DNA replication?
process in which DNA is copied
What are the two most important enzymes in DNA replication?
DNA Helicase and DNA polymerase
What is STEP 1 of DNA replication?
DNA helicase opens up the DNA
What enzyme is important to STEP 1 of DNA replication?
DNA helicase
The area where helicase is separating the DNA is called __________________ _______________.
Replication fork
What is STEP 2 of DNA replication?
DNA polymerase will start to build new complementary strands
What is DNA polymerase adding to form a new strand of DNA?
Nucleotides
DNA strands are copied in opposite directions. This is because DNA is _____________.
anti parallel
What is STEP 3 in DNA replication?
DNA Polymerases will detach after two, new DNA molecules are formed
At the end of replication, each new DNA molecule will consist of one ____________ strand and one _____________ strand.
old and new
DNA is semi-conservative. What does that mean?
The new DNA molecules consists of 2 strands, one strand is from the original DNA helix and the second strand is newly formed by the DNA polymerase
Why are there minimal errors made during DNA replication?
DNA polymerase has the ability to proof-read and go back and fix errors
In eukaryotic organisms, how many replication forks are there? And why?
Multiple replication forks to move process along faster
In prokaryotic organisms, how many replication forks are there? And why?
2 replication forks because they have circular DNA and the replication forks go around the circle and meet in the middle.
