Best Answer

Nuclease are enzymes in a cell that break apart RNA and DNA so that their parts can be recycled, and yes human cells contain these enzymes.

If you meant nucleus, which is where the DNA resides in a (most) cells, then yes, most human cells contain a nucleus (the most notable exception being red blood cells).

No, humans do not have restriction enzymes in their bodies.

Restriction enzymes are enzymes that cut at specific sites in DNA. These are found only in prokaryotes (i.e. cells that do not have a nucleus - that is, organisms in bacteria and archaea domains). Consequently, you won't find them in humans.
