Question

Drag each tile to the correct box. Arrange these steps of DNA replication in the order in which they occur. RNA primase synthesizes RNA primer, which attaches itself at the initiation point. Polymerase begins synthesizing the new strands. Single-strand binding proteins prevent the strands from snapping back to the original DNA structure. Ligase joins the Okazaki fragments.

Answer 1

Answer: 1) Single-strand binding proteins prevent the strands from snapping back to the original DNA structure.

2) RNA primase synthesizes RNA primer, which attaches itself at the initiation point.

3) Polymerase begins synthesizing the new strands.

4) Ligase joins the Okazaki fragments.

Explanation: The correct order of those steps pf DNA replication is:

1) First, Single-strand binding proteins (SSBs) prevent the binding of DNA strands after helicase break the hydrogen bond between them.

2) RNA prymase synthesizes primers which attache at the iniciation point in strands, so the DNA polymerase could begin to replicate them.

3) DNA polymerase begin to replicate the strands.

4) Finally, ligase joins the fragments of DNA after primers were eliminated.
