Solution

The statements provided contain several inaccuracies regarding the process of DNA replication. Here are the correct explanations:

  1. DNA Ligase: This enzyme does not replace RNA primers with DNA nucleotides. Instead, DNA ligase's role is to join Okazaki fragments, which are short sequences of DNA nucleotides, on the lagging strand during DNA replication.

  2. DNA Polymerase III: This enzyme does indeed pair Guanine with Cytosine, but it also pairs Adenine with Thymine. It's the main enzyme involved in DNA replication, adding nucleotides to the leading strand and to the Okazaki fragments on the lagging strand.

  3. DNA Polymerase I: This enzyme does not pair Adenine with Cytosine. Like DNA Polymerase III, it pairs Adenine with Thymine and Guanine with Cytosine. Its main role is to replace RNA primers with DNA nucleotides.

  4. Okazaki Fragments: These are short sequences of DNA nucleotides that are synthesized discontinuously on the lagging strand during DNA replication. They are not created on the leading strand, which is synthesized continuously.
