Drag each tile to the correct box. order the events that occur during dna replication. dna polymerase removes rna primers and replaces them with dna nucleotides. rna primase synthesizes a primer which attaches to the initiation point. dna ligase seals the gaps between new dna and okazaki fragments. dna helicase unwinds the dna. dna polymerase extends the primer by adding nucleotides that are complementary to the template strand.
