Enzymes
This is the enzyme that "unzips the DNA molecule"
What is helicase?
This is the word for one half of the replication bubble
What is the replication fork?
This is the first step in DNA replication
What is helicase unzips the DNA, forming a replication fork
This is the strand which has the continuous building of new DNA in a 5' to 3' direction
What is the leading strand
The start site of DNA replication in prokaryotes
What is the origin?
This is the enzyme that adds new nucleotide bases to the parent or template strand to form a new DNA strand
What is DNA Polymerase (III)
This is a permanent mistake in DNA replication
What is a mutation?
DNA polymerase III can add DNA nucleotides continuously in this direction
What is DNA polymerase III adds nucleotides continuously in a 5' to 3' direction
Has the Okazaki fragments
What is the lagging strand?
This is the site where DNA replication ends in prokaryotes
What is the termination site
This is the enzyme that joins the Okazaki fragments on the lagging strand together
What is DNA Ligase?
The partnering of nucleotide bases on DNA ...
What is A=T, G=C
This is why DNA polymerase III cannot add nucleotides continuously to the lagging strand
What is DNA polymerase cannot continuously add nucleotides in a 3' to 5' direction
Builds in the 3' to the 5' direction
What is the lagging strand?
True of false:
DNA replication in eukaryotes requires many replicons/replication bubbles
What is true?
This is the enzyme that replaces the RNA primers.
What is DNA Polymerase I
These are the fragments formed on the lagging strand by DNA Polymerase III.
What are Okazaki fragments?
After the RNA primers are removed from the lagging strand this must happen
What is DNA ligase must join together the Okazaki fragments?
Haas many RNA primers
What is the lagging strand
This model for DNA replication was found to be false and would have involved "producing" 2 DNA molecules where one was all the original DNA and one was all new DNA.
What is the conservative model?
This is the enzyme which adds RNA primers
What is DNA primase?
This is why DNA coils and RNA does not
What is an oxygen on the pentose (5 carbon sugar) which is removed in DNA and not in RNA?
This is the model which represents DNA replication
What is the semi-conservative model?
Forms a new "daughter" strand of DNA by using the "parent" strand as a template
What is both
What is the S phase of interphase?
