DNA Replication Vocabulary || QUESTIONS WITH
ACTUAL ANSWERS!!
DNA Replication correct answers the process of making identical copies of DNA before cell
division
Replication Origin correct answers Specific sequence of DNA where DNA synthesis begins.
Semiconservative replication correct answers Each half of an original DNA molecule serves
as a templete for a new strand, and the two new DNA molecules each have one old and one
new strand.
helicase correct answers An enzyme that unwinds the double helix of DNA and separates the
DNA strands in preparation for DNA replication.
DNA Polymerase correct answers Enzyme involved in DNA replication that joins individual
nucleotides to produce a DNA molecule
RNA Primer correct answers Sequence of RNA nucleotides bound to a region of single-
stranded DNA to initiate DNA replication.
leading strand correct answers the strand of DNA that is continuously synthesized during
replication
lagging strand correct answers The strand that is synthesized in fragments using individual
sections called Okazaki fragments
Okazaki fragments correct answers Small fragments of DNA produced on the lagging strand
during DNA replication, joined later by DNA ligase to form a complete strand.
DNA ligase correct answers enzyme which connects the individual Okazaki fragments on the
lagging strand
Denaturing correct answers changing the conformation of a protein through, pH, temperature,
or salt concentration changes.
direction of replication correct answers 5' to 3' direction
topoisomerase correct answers A protein that functions in DNA replication, helping to relieve
strain in the double helix ahead of the replication fork.
double helix correct answers The form of native DNA, referring to its two adjacent
polynucleotide strands wound into a spiral shape.
DNA helicase correct answers An enzyme that unwinds the DNA double helix during DNA
replication
RNA primase correct answers An enzyme that creates a short RNA primer for initiation of
DNA replication.
