DNA Replication

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.
