chromosomes are found in what part of the cell?
cytoplasm
chromatin allows the very long dna molecules to fit into the cell nucleus. during cell division chromatin condenses further to form microscopically visible chromosomes. the structure of chromosomes varies through the cell cycle. during cellular division chromosomes are replicated, divided, and passed successfully to their daughter cells so as to ensure the genetic diversity and survival of their progeny. chromosomes may exist as either duplicated or unduplicated. unduplicated chromosomes are single double helixes, whereas duplicated chromosomes contain two identical copies (called chromatids or sister chromatids) joined by a centromere.

after the completion of binary fission or cell reproduction involving mitosis, each daughter cell has the same amount of dna (z) as what the parental cell had before it replicated its dna. these two types of cell reproduction produced two daughter cells that have the same number of chromosomes as the parental cell. chromosomes duplicate prior to cell division when forming new skin cells for reproduction. after meiotic cell reproduction the four daughter cells have half the number of chromosomes that the parental cell originally had. this is the haploid amount of dna, often symbolized as n. meiosis is used by diploid organisms to produce haploid gametes. in a diploid organism such as the human organism, most cells of the body have the diploid amount of dna, 2n. using this notation for counting chromosomes we say that human somatic cells have 46 chromosomes (2n = 46) while human sperm and eggs have 23 chromosomes (n = 23). humans have 23 distinct types of chromosomes, the 22 autosomes and the special category of sex chromosomes. there are two distinct sex chromosomes, the x chromosome and the y chromosome. a diploid human cell has 23 chromosomes from that person's father and 23 from the mother. that is, your body has two copies of human chromosome number 2, one from each of your parents.
