Most of the human DNA, or human genes, are located in the chromosomes.
Each metaphase chromosome consists of:
two sister chromatids containing one DNA molecule each, and since they are formed by replication, these molecules are completely identical in gene content; that is why chromatids are called sister chromatids; two centromeres, one on each chromatid.
The answer is A. When mitosis is complete, t<span>wo genetically identical daughter nuclei are produced.</span>

hope this make sense:)
The basic structure of a cell membrane is in three parts; the internal membrane surface, the external membrane surface and the intervening phospholipid material. This intervening material is impermeable to ions and polar molecules and it prevents polar solutes likie amino acids from moving across the membrane but permits the passive diffusion of hydrophobic molecules.. The external and internal cell membranes are selectively permeable and can regulate what comes into or goes out of the cell and in so doing allows for the transport of materials needed for survival.
