DNA in prokaryotes & Eukaryotes
Enzymes and their functions
The Process of Replication
The Leading and Lagging Strands
Identification
100
The phase when DNA is replicated in a eukaryote .
What is S?
100
This enzyme splits the original DNA strand in two, starting the process of Replication.
What is Helicase?
100
This is the end result of replication.
What is two identical strands?
100
On this strand, DNA polymerase works in a single continuous process.
What is the leading strand?
100
Identify C
what is Helicase?
200
DNA polymerase needs a _______ to be able to add nucleotides complementary to template strand.
What is a RNA primer?
200
This enzyme adds complementary base pairs to both strands.
What is DNA Polymerase?
200
DNA is always replicated (built) in this direction. (looking at the new strand)
What is 5' to 3'?
200
This strand is worked in the opposite direction of the Helicase.
What is the Lagging strand?
200
Identify A
What is DNA polymerase?
300
The number of origin points in a prokaryote
What is one?
300
This is the name for the area opened by Helicase.
What is a replication fork?
300
After replication of DNA each identical chromosome is made up of a template strand and a newly constructed strand.
What is semi-conservative replication?
300
The lagging strand is made up of this type of segment.
What are Okazaki fragments?
300
Identify E
What is DNA primase?
400
The structure of a eukaryotic chromosome.
What is a linear strand?
400
This enzyme removes the Primer set by Primase.
What is RNAase?
400
This is the last thing that occurs before the end of replication.
What is Ligase filling in the gaps left by DNA Polymerase?
400
The strand that works towards the replication fork.
What is leading strand?
400
Identify D
What is the lagging strand?
500
The template strand of DNA is “read” in this direction in prokaryotes.
What is the 3’—>5’ direction?
500
This enzyme is responsible for joining together the Okazaki fragments on the lagging strand.
What is DNA Ligase?
500
This many replication forks can exist on the same strand of DNA at once.
What is more than one?
500
The lagging strand creates Okazaki fragments for this reason.
What is DNA polymerase traveling away from the Helicase?
500
Identify AB
What is the template DNA strand?
