The reaction in DNA replication that is catalysed by DNA ligase is the formation of a phosphodiester linkage between two Okazaki fragments.

Here are the steps:

1. During DNA replication, the DNA molecule unzips, and new nucleotides are added to each strand by DNA polymerase.

2. On the leading strand, this process is continuous. However, on the lagging strand, replication occurs in segments known as Okazaki fragments.

3. These fragments are separate pieces of DNA, and they need to be joined together to form a continuous strand.

4. This is where DNA ligase comes in. DNA ligase catalyses the formation of a phosphodiester bond between the 3' end of one fragment and the 5' end of the next.

5. This reaction joins the Okazaki fragments together, resulting in a continuous DNA strand.

So, DNA ligase plays a crucial role in DNA replication, ensuring that the newly synthesized DNA is continuous and complete.
