Document Summary
Self reproduction the instructions in our model are coded in the dna in the form of chromosomes and the object that is being replicated is the cell. Length of chromosomes in units of base pairs (bp) Gene is a sequence of bp, a sequence of dna. Human genomes, 23 different chromosomes 46 total chromosomes. Mitosis: division of the genetic material in the nucleus that produces daughter cells. Genetically identical to the parent cell: mitosis is the basis of asexual reproduction and is involved only in the production of somatic (body) cells. Meiosis: division of the genetic material in the nucleus to produce daughter cells with half the amount of hereditary material found in the parent cell. Involved only in the production of gametes (eggs and sperm); it is the basis of sexual reproduction and genetic inheritance. Salamander has the most number of chromosomes of any organisms: the cell cycle. Move to other locations in the body.
