When DNA fragments are joined with a DNA ligase, an array of products are created. How does this happen?

Answer and explanation; DNA ligase is a DNA-joining enzyme. If two pieces of DNA have matching ends, ligase can link them to form a single, unbroken molecule of DNA. DNA ligase usesATP as an energy source to catalyzes a reaction in which the phosphate group sticking off the 5' end of one DNA strand is linked to the hydroxyl group sticking off the 3' end of the other. The reaction produces an intact sugar-phosphate backbone of the DNA strand.
