Document Summary
Interphase: g1, dna synthesis (replication, g2, mitosis/meiosis. Cell reproduction: two steps, karyokinesis division of the nucleus, mitosis, meiosis, cytokinesis division of the cytoplasm. Identical to parental cell (nucleus: prophase, nuclear envelope breaks down, spindle apparatus forms, chromosomes condense and are attached to the spindle, all chromosomes are replicated (four chromosomes, eight molecules of. P or p: cross that involves two different genes.
