Nuclear Transfers for the Uptown Bus
Scientists found that they could make clones through a process called nuclear transfer. Nuclear transfer uses the technology that puts a sperm into an egg for artificial fertilization, but takes it a step further.
Almost all cells have a nucleus. A nucleus is where the DNA or genetic blueprint for life is located inside the cell. When you remove the nucleus, it is called enucleation. Pronounced: E' - new - klee - a - shun. Removing the nucleus requires the use of a small needle that is inserted into the cell. The needle sucks the nucleus out of the cell. The same process is performed on another cell. The nuclei can be switched then. The cells recover from the needle wound and start working again.
