Summary Introduction
Introduction:
Almost all the reactions of the body are controlled or governed by one other enzyme. Like for example if we take the case of digestion there are many enzymes that are involved in the process of digestion so is the case with the replication of DNA. In the process of replication of DNA there are certain enzymes that are needed for the process to be carried out. For example: DNA gyrase, DNA helicase, DNA polymerase and so on.

Which of the following statements is FALSE regarding the molecular mechanism for DNA polymerases?
A.
The active site contains 2 divalent metal ions
B.
A single stranded DNA template is required
C.
The enzyme can only attach a new deoxynucleotide to the 5’ end of a growing chain
D.
The 3’OH on the deoyxyribose ring attacks a phosphate of a dNTP to produce a new phosophodiester bond
E.
None of the above (all are true statements)
Which statement about Okazaki fragments is true?
Select one:
a. DNA polymerase doesn’t need a primer to build these fragments
b. They act as a primer that initiates DNA replication.
c. They correct errors made during earlier phases of DNA replication.
d. They are necessary because DNA polymerase can only build DNA in the 5’ to 3’ direction, so for one of the strands at each fork, the DNA polymerase can only buildaway from the fork.
e. They prevent the ends of chromosomes from shortening with every replication.
All of the following statements about telomerase are correct except:
A. the RNA component acts as a template for the synthesis of a segment of DNA.
B. it adds telomeric repeats to the 5'-ends of the DNA strands.
C. it provides a mechanism for replicating the ends of linear chromosomes.
D. it recognizes a G-rich single strand of DNA
E. it is a reverse transcripcase.
