100
The replication of a DNA molecule begins at this particular site.
What are origins of replication?
100
This enzyme catalyzes the synthesis of new DNA by adding nucleotides to a preexisting chain.
What is DNA polymerase?
100
Template strand replicated away from the start of replication.
What is the lagging strand?
200
Proteins separate two strands of DNA creating this type of bubble.
What is replication?
200
This enzyme starts a complementary RNA chain from a single RNA nucleotide.
What is primase?
200
These are segments of discontinuous strands synthesized during replication.
What are Okazaki fragments?
300
This Y shaped region is where the original strands of DNA are being unwound.
What is a replication fork?
300
The enzyme that untwist the double helix at the site of replication to separate DNA strands.
What is helicase?
300
This molecule is responsible for replacing RNA nucleotides with DNA nucleotides during replication.
What is DNA plymerase I?
400
Unwound sections of the DNA strand that serves as a replication template is known as this.
What is parental strand?
400
Helps to relieve the twisting and strain of unwinding DNA by breaking, swiveling and rejoining DNA strands.
What is topoisomerase?
400
DNA enzymes add nucleotides to this end of a growing DNA strand during replication?
What is 3'?
500
The RNA chain that produced by enzymes during replication and is genrally is 5-10 nucleotides long.
What is a primer?
500
The enzyme that joins the sugar phosphate back bones of all DNA fragments into a continuous DNA strand.
What is ligase?
500
These are special nucleotide sequences at the ends of eukaryotic chromosomal DNA.
What are telomeres?
