Nucleus A cellular organelle of eukaryotes , enclosed in a definite membrane that is essential to cell functions. Its center is called a nucleolus, which contains the DNA (chromosomes ) along with proteins that aid its replication

with an egg with the DNA nucleus removed. Via somatic nuclear transplantation--cloning--we could insert the DNA nucleus of the future transplant recipient. We could then turn on selected genes--that is, we could cause the stem cell to

dense, positively charged nucleus surrounded by negatively charged electrons . Ernest Rutherford proposed a planetary model for the atom - electrons in orbit around a nucleus like planets around a star. The fly in the ointment was

interacts with the DNA nucleus, and to gain the ability to reprogram cytoplasm to make specific tissue. Once this ability to reprogram is achieved, then in principle it could be used with any cell. We would not necessarily at that point have

of cells that have a nucleus (i.e., the nucleus, where the genetic material resides, is sepa­rated from the rest of the cell, called the cytoplasm , by a complex membrane called the nuclear envelope). The earliest single-celled forms of

that takes place in the nucleus of a dividing cell, involves typically a series of steps consisting of prophase, metaphase, anaphase, and telophase , and results in the formation of two new nuclei each having the same number of chromosomes

The removal of the DNA nucleus from the donated oocyte might be considered the destruction of a potential human life; and the insertion of a DNA nucleus appears to be an asexual creation of a human embryo . We suddenly find ourselves in the
