Document Summary

Occurs in the nucleus of eukaryotic cells by mitosis and meiosis: replacement of the entire lining of your small intestine, liver cells only divide for repairing, nerve cells do not divide. Long and thin for replication and decoding. Become short and fat prior mitosis easier to separate due to compact form. In spore formation which precedes gamete production in plants. During the production of sex cells (gametes) in animals. Haploid gametes (sperm ovum) - sexual reproduction. Dna in a cell replicates only once, but cell divides twice. Interphase: g1: protein synthesis and growth (10 hours) Preparation for dna replication (e. g. growths of mitochondria) Differentiation, only selected genes are used to perform different functions in each cell: s: dna replication (9 hours, g2: short gap before mitosis, organelles and proteins for mitosis are made (4 hours) M-phase: mitotic division of the nucleus (prophase, metaphase, anaphase, telophase, cytokinesis (division of the cytoplasm) Phase with highest metabolism (mitochondria have a high activity)
