Also, because the chromatids are stuck together after replicating, it is also reasonable to say that there are 46 pairs of chromatids (or chromosomes) at the end of S phase. If the cell goes through mitosis (normal cell division) those 46 pairs will separate and the two daughter cells will have 46 chromosomes.
Estimates of the survival of infants and children in a persistent vegetative state, based on the clinical experience of pediatric neurologists, were published recently10. These estimates range from 4.1 Â±0.7 years, for infants up to 2 months of age, to 7.4 Â±1.8 years, for children 7 to 18 years old.
Persistent vegetative state is the standard usage (except in the UK) for a medical diagnosis, made after numerous neurological and other tests, that due to extensive and irrevocable brain damage a patient is highly unlikely ever to achieve higher functions above a vegetative state.
