How to group the DNA manipulative enzymes?

DNA manipulative enzymes:

1. An enzyme that changes already integrated bases or adds minor bases to DNA or RNA and serves to change the sequence so that the strand won't be harmed by restriction enzymes.
2. DNA ligases and restriction enzymes serve as the cutting and joining mechanisms in DNA manipulation.
3. The large category of enzymes known as DNA modifying enzymes includes all additional enzymes utilised in genetic engineering.
4. These enzymes are involved in the production, modification, and breakdown of nucleic acids.

Some of the DNA manipulative enzymes are:

1. Ligases – bind together the nucleic acid molecules.
2. Nucleases – enzymes that snip, degrade or shorten the nucleic acid molecules.
3. Modifying enzymes – add or eliminate chemical groups.
4. Polymerases – generates copies of molecules.
