Textbook Question
Chapter 16, Problem 9TYK
DNA polymerase is not able to begin copying a DNA strand on its own. How is the replication of DNA initiated?
- a. A coenzyme joins to the polymerase to allow it to begin synthesizing DNA.
- b. Short single-stranded DNA molecules called primers exist in the nucleus, and they bind to the DNA to allow synthesis to begin.
- c. An enzyme called primase creates a short RNA primer that can be extended by DNA polymerase.
- d. Telomerase extends the DNA strand to create a starting point.

Students have asked these similar questions
What is DNA polymerase?
a.An enzyme that carries out DNA replication
b.Short, single strand of DNA that base-pairs with a specific DNA sequence
c.An enzyme that corrects mutations that arise during the replication of DNA
d.An enzyme that seals any gaps that remain between bases of replicating strands of DNA
DNA strands are anti-parallel and DNA polymerase can only synthesize DNA in a 5' to 3' direction. How does the enzyme synthesize both strands at the same time?
A. The leading strand is sythesised in Okazaki fragments
B. The lagging strand is synthesised in short Okazaki fragments.
C. Only one strand is replicated.
D. There are more than one DNA polymerase involved.
What is the correct chronological order of the initiation of DNA replication?
A. Hydrogen bonds between complementary base pairs are broken at origin of replication
B. Primase binds to the site of origin.
C. DNA polymerase binds to the template strand.
D. An RNA primer is synthesized.
E. Incoming deoxynucleoside triphosphates are added to the growing strand.
