A biochemist is using a biochemical assay to study DNA in a test tube. When she places a DNA molecule together with nucleotides and all the necessary enzyme, the DNA replicated in a semi-conservative manner. One day something went wrong with the reaction; instead of two perfect copies of the DNA molecule, her reaction yielded two template strands bound to short strands of RNA. The biochemist probably forgot to add which of the following to the reaction?
a. dna pol I
b. dna pol III
c. dATP, dCTP, dGTP, dTTP
d. dna ligase
e. b and c
a. DNA pol I
Explanation: DNA polymerase I is a replication enzyme that involves in removal of RNA primer and replace its by DNA.
