5600669884MitosisCell division that produces normal cells, produces two identical daughter cells.0
5600669885MeiosisCell division that produces reproductive cells in sexually reproducing organisms, produces four identical daughter cells.1
5600669887CentriolesIn animal cells, a pair of centrioles organize microtubules into spindle fibers. These guide chromosomes in mitosis.2
5600669888IPMATPneumonic device to remember the stages and order of cell division: Interphase, Prophase, Metaphase, Anaphase, and Telophase.3
5600669889Interphase90% of the cell cycle. The cell does its "everyday job": RNA is produced, proteins are synthesized. The cell is preparing for duplication -- it is ready whenever it is triggered.4
5600669891G1 PhaseInitiated by a signal to divide. 1st growth period of the cell. Cell does its "everyday job." Cell grows, preparing for division.5
5600669892S PhaseDNA Synthesis. The cell copies chromosomes.6
5600669893ChromatinThe DNA-Protein complex formed when DNA molecules wrap around histone proteins.7
5600669894ChromosomesA doubled rod of condensed chromatin; contains DNA that carries genetic information.8
56235517794NTretaploid, four copies of each chromosome, a cell ready for division9
5600669895CentromeresArea where the chromatids of a chromosome are attached.10
5600669896Sister ChromatidsReplicated forms of a chromosome joined together by the centromere and eventually separated during mitosis.11
5600669897Homologous ChromosomesChromosomes that have the same sequence of genes, that have the same structure, and that pair during meiosis. Code for the same gene, but may have different alleles.12
5600669898G2 PhaseThe cell prepares for division. Cell grows even more. Produces more organelles, proteins, and membranes.13
5600669901ProphaseChromatin condenses. Centrioles move to opposite poles of cell. Protein fibers cross cell to form mitotic spindle. Nuclear membrane breaks down.14
5600669903PrometaphaseTransition to metaphase. Spindle fibers attach to centromeres. Microtubules attach at kinetochores. Chromosomes begin moving.15
5600669904KinetochoresAttachments between the microtubules and sister chromatids.16
5623413613spindlefanlike microtubule structure that helps separate the chromosomes during mitosis17
5600669906MetaphaseChromosomes align along middle of cell, ensuring chromosomes separate properly.18
5600669907Metaphase PlatePlane midway between the two poles of the cell where chromosomes line up during metaphase.19
5600669909AnaphaseSister chromatids separate at kinetochores. Poles move farther apart.20
5600669912Chromosome MovementKinetochores use motor proteins that "walk" chromosomes along attached microtubule. Microtubule shortens by dismantling at kinetochore.21
5600669913TelophaseChromosomes arrive at opposite poles. Spindle fibers disperse. Cytokinesis begins.22
5600669915Cytokinesis in PlantsA cell plate forms between the divided nuclei that develops into cell membranes. A cell wall then forms in between the two new membranes23
5600669916Cytokinesis in AnimalsConstriction belt of actin microfilaments around equator of cell. Cleavage furrow forms. Splits cell in two, like tightening a draw string.24
5600669917Cleavage FurrowThe first sign of cleavage in an animal cell; a shallow groove in the cell surface near the old metaphase plate.25
5600669918Cytokinesis in PlantsCell plate forms from vesicles lining up at the equator. They proceed to fuse and form two cell membranes. A new cell wall is laid between membranes. The new cell wall fuses with the existing cell wall.26
5600669919Evolution of MitosisIn, eukaryotes likely evolved from binary fission in bacteria (single circular chromosome with no membrane bound organelles).27
5600684204CancerA collection of related diseases in which cells divide uncontrollably28
5600694557G1 checkpointAt the end of G1 phase, if cell is not ready to divide it may arrest here (G0 phase - nerve and muscle cells remain here, rarely divide after maturing) and never proceed or wait until it is ready.29
5600718816S checkpointDNA damage checkpoint: DNA recplication halted if genome is damage30
5623281786cyclinone of a family of proteins that regulates the cell cycle in eukaryotic cells31
5623325630gameteA haploid cell such as an egg or sperm. Gametes unite during sexual reproduction to produce a diploid zygote.32
5623327866zygoteA fertilized egg33
5623382762binary fissionA form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size34
5623400924buddingAsexual reproduction in which a part of the parent organism pinches off and forms a new organism35
5623418992parthenogenesisAsexual reproduction in which females produce offspring from unfertilized eggs. No males involved.36
5623430112chiasmataThe microscopically visible site where crossing over has occurred between chromatids of homologous chromosomes during prophase I of meiosis.37
5623439972crossing overProcess in which homologous chromosomes exchange portions of their chromatids during meiosis.38
5623444913point of sexual reproductionincrease variation in offspring, increase diversity in a population39
5623459992DNA replicationDNA unzips into two parts and splits with the cell. In it's new home each side of the DNA strand attack to matching nucleotides to create 2 exact copies. It is important in puberty and other times of growth as it is the reproducing of your cells.40
5623463642DNA Polymerase IIIAn enzyme that catalyzes the elongation of a DNA strand in the 5' → 3' direction.41
5623471741DNA LigaseA linking enzyme essential for DNA replication; catalyzes the covalent bonding of the 3' end of a new DNA fragment to the 5' end of a growing chain.42
5623474700DNA HelicaseAn enzyme that unwinds the DNA double helix during DNA replication43
5623484965semi-conservative replicationin each new DNA double helix, one strand is from the original molecule, and one strand is new44
5623492812Meselson and Stahl experimentCultured bacteria in a medium containing heavy Nitrogen (15N) then moved them to a medium containing light Nitrogen (14N). Here they allowed the bacteria to replicate and divide once. The new strands possessed one heavy strand and one light strand.45
5623505320Okazaki fragmentsSmall fragments of DNA produced on the lagging strand during DNA replication, joined later by DNA ligase to form a complete strand.46
5623509230leading strandthe new continuous complementary DNA strand synthesized along the template strand in the mandatory 5' --> 3' direction47
5623511343lagging strandThe newly forming daughter strand of DNA that is replicated in a discontinuous fashion, via Okazaki fragments that will ultimately be ligated together; the daugther strand that is replicated in the opposite direction that parallel DNA is unwinding48
5623519280RNA PrimaseAn enzyme that creates an single stranded RNA primer, which serves as a starting point for DNA replication.49
