1. Rearrange the following statements in the correct order:

a. Phosphodiester bonds forms between the newly added nucleotide

b. The enzyme helicase binds to the replication origin and unwinds the DNA helix

c. DNA ligase seals up fragments of DNA, and repairs the strand of DNA

d. RNA primers are added to being the replication process

e. Polymerase I replaces the RNA primers with DNA

f. Polymerase III begins to build a new strand of DNA using nucleoside triphosphates

g. A replication fork is created as the two strands separate

h. Any damage or errors to DNA are repaired by Polymerase II

Correct order:

2. DNA replication in a eukaryotic cell is initiated at many points along the DNA strand. Because of this, replication can occur at all of these points simultaneously. The image shows a replication bubble. Explain how each DNA template strand can be both a leading strand and a lagging strand at the same time
