Not all cells have 46 chromosomes. Somatic cells do have 46 chromosomes, but Reproductive cells (egg and sperm) only have 23 chromosomes. Yes all of the DNA in your cells is the same with the same chromosomes. What type of cell it is determines what part of your genetic code it reads. Yes, except sex cells, which have half of the DNA material present in other cells. This is so that when the sperm cell 'unites' with egg cell, DNAs would combine and form bigger diversity, which is a good thing. Yes, all cells (other than gametes and red blood cells) contain all your genetic information.
