Why is it necessary to "starve" the donor cells prior to reproductive cloning? to force the enucleated egg cell into g0 stage so that it would accept the donor nucleus to make the nucleus "start over" in the s stage so that the nucleus will be haploid to make the nucleus "start over" in the s stage so that the nucleus will be diploid to lengthen the telomeres in the donor nucleus to force the cells into g0 stage so that the nuclei removed from them will respond to cytoplasmic growth signals?

Production of an animal, which is genetically similar to a donor animal via somatic cell nuclear transfer is termed as reproductive cloning. In the process, the newly developed embryo is administered back into the uterine surroundings, where it can implant and develop.  

However, in the process it is essential to starve the donor cells before going through the process of reproductive cloning is as it forces the cells into the G0 stage so that the nuclei withdrawn from them will react towards the cytoplasmic growth signals.  

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
