DNA Synthesis

Part A

This enzyme catalyzes DNA synthesis.
Part B

When a primer is added to a single strand of DNA, DNA polymerase can start adding nucleotides to synthesize a complementary strand.
Part C

The potential energy stored in the bonds of the phosphates provides the energy for DNA synthesis.
Part D

This RNA polymerase synthesizes an RNA primer antiparallel to the template DNA strand.
Part E

While DNA is synthesized continuously on the leading strand, Okazaki fragments are formed on the lagging strand because DNA synthesis always proceeds in the 5’ to 3’ direction.
Part F

This enzyme untwists the coils that occur in the DNA as it is being unwound into a single-stranded template.
Part G

When the 3’ end of one DNA strand points in the same direction as the 5’ end of the other DNA strand, the strands are said to be antiparallel.
