Here's a breakdown:
* Enucleated egg cell: This is an egg cell that has had its own nucleus removed, leaving only the cytoplasm and other cellular components.
* Nucleus from a cell of one animal: This nucleus contains the complete genetic material (DNA) of the donor animal.
The process involves taking the nucleus from a somatic (body) cell of the animal you want to clone and transferring it into the enucleated egg cell. The egg cell is then stimulated to start dividing, creating an embryo that is genetically identical to the donor animal.
This is a simplified explanation of a complex process, but hopefully it clarifies the basic concept!
