Question

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

Explanation:

1. DNA replication starts with unwinding the double helix, done by helicase.
2. Next, RNA primase makes a primer to start DNA synthesis.
3. DNA polymerase then adds complementary nucleotides to extend the primer.
4. Finally, DNA ligase seals gaps between Okazaki fragments on the lagging strand.

Answer:

1. DNA helicase unwinds the DNA.
2. RNA primase synthesizes a primer which attaches to the initiation point.
3. DNA polymerase extends the primer by adding nucleotides that are complementary to the template strand.
4. DNA ligase seals the gaps between new DNA and Okazaki fragments.
