Cell Reproduction
Coil (n)
A series of connected spirals or concentric rings formed by gathering or winding:
exp: Tod slung the coil of rope over his shoulder.
Replicate(v)
To reproduce or make an exact copy or copies of (genetic material, a cell, or an organism).
exp: He was not able to replicate this experiment.
Thread(n)
Fine cord of a fibrous material, such as cotton or flax, made of two or more filaments twisted together and used in needlework and the weaving of cloth.
exp: "More than 90 geologic faults thread the Los Angeles area" (Science News).
Nuclear(n)
Biology Of, relating to, or forming a nucleus
exp: "annexation of the suburban fringe by the nuclear metropolis"
Membrane(n)
A thin, pliable layer of tissue covering surfaces or separating or connecting regions, structures, or organs of an animal or a plant.
exp: the membrane that forms the wall of the blastocyst in early development
Disintegrate(v)
To become reduced to components, fragments, or particles.
exp: The paper bag was so wet that the bottom disintegrated and all the groceries fell out.
Attach(v)
To fasten, secure, or join
exp: "The spider's thread attached to the window sill"
Pole(n)
Either extremity of an axis through a sphere.
exp: the moral poles of modern medicine: on the one hand, a tinkering with procreation with at best ambiguous, at worst monstrous moral possibilities. On the other hand, scientific skill and cunning unambiguously in the service of hope" (Charles Krauthammer)
Unwind(v)
To reverse the winding or twisting of.
exp:Give me a chance to unwind!
Reform(n)
To improve by alteration, correction of error, or removal of defects; put into a better form or condition.
exp:He admitted that he had been a criminal, but said that he intended to reform
Centromere(n)
The most condensed and constricted region of a chromosome, to which the spindle fiber is attached during mitosis.
exp: "the centromere is difficult to sequence".
Gamete(n)
A reproductive cell having the haploid number of chromosomes, especially a mature sperm or egg capable of fusing with a gamete of the opposite sex to produce the fertilized egg.
exp:Gametes are mature sexual cells with unpaired chromosomes.
Chromatid(n)
Coil (n)

A reproductive cell having the haploid number of chromosomes, especially a mature sperm or egg capable of fusing with a gamete of the opposite sex to produce the fertilized egg.
exp:Gametes are mature sexual cells with unpaired chromosomes.
Chromatid(n)
Either of the two daughter strands of a replicated chromosome that are joined by a single centromere and separate during cell division to become individual chromosomes.
exp: An exchange of homologous segments of genetic material between the sister chromatids of a chromosome, either between the sister chromatids of a meiotic tetrad or between the sister chromatids of a duplicated somatic chromosome.
Dividson(n)
The act or process of dividing.
exp: "two infantry divisions were held in reserve"
Prophase(n)
The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell.
exp:“Diagrams of late prophase chromosomes (1000-band stage) of human, chimpanzee, gorilla, and orangutan (left to right for each number).”
Metaphase(n)
The stage of mitosis and meiosis, following prophase and preceding anaphase, during which the chromosomes are aligned along the metaphase plate.
exp:Prophase comes before metaphase in the cell cycle.
Anaphase(n)
The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle.
exp:“Seldom has the word "anaphase" held more suppressed longing.”
Telophase(n)
The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.
