Term | Definition |
Mitosis | cell division resulting in two identical, diploid, daughter cells for growth and repair |
Meiosis | cell division resulting in four haploid cells containing half of the chromosomes the parent cell had, production of gametes (sex cells) |
Interphase | NOT PART OF MITOSIS, stage where cells grow before DNA is duplicated and prepares for division (contains G1*growth, Synthesis*replication, and G2*getting ready for division) |
Prophase | stage where DNA starts to condense, microtubules assembled and bring centrioles to opposite sides of the cell, nuclear envelope starts to break up |
Metaphase | stage where chromosomes line up at the middle of the cell |
Anaphase | stage where sister chromatids break apart and start to move to opposite spindle poles |
Telophase | stage where chromosomes decondense and nuclear membrane starts to reform |
Interphase | stage where two daughter cells have formed, each diploid |
Cytokinesis | process that pinches the cells apart, cytoplasm is NOT EVENLY SPLIT |
Haploid | having a single set of unpaired chromosomes |
Diploid | containing two complete sets of chromosomes, one from each parent |
Crossing Over | in Meiosis, the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring after tetrads are formed |
Binary Fission | division of prokaryotic cells, cells that possess a single chromosome which is replicated and the cell is divided |
Prophase 1 | stage where tetrads form and synapse (crossing over) |
Metaphase 1 | stage where tetrads split |
Anaphase 1 | stage where chromosomes move to opposite ends |
Telophase 1 | stage where there are two haploid cells |
Telophase 2 | stage where there are four haploid cells |
