Because of the fission process that consumes the fuels, the old fuel rods must be changed periodically to fresh ones (this period is called a cycle). However, only a part of the assemblies (typically one-third) are removed since the fuel depletion is not spatially uniform.
In fertilization, the sperm and egg both contain one set of chromosomes. the father (sperm) and one from the mother (egg). In SCNT, the egg cell's single set of chromosomes is removed. chromosomes. come from the somatic cell.
Here we focus on reproductive cloning of organisms. Reproductive cloning is the process by which a whole organism is cloned. First, a cell is taken from the organism that is being cloned. The DNA from this donor cell is then transferred to an egg cell whose DNA has been removed.The egg cell is âactivatedâ and begins dividing as if it was fertilized.ere we focus on reproductive cloning of organisms.
