mitosis vs meiosis

mitosis meiosis

Definitions

  • 1) cytology The division of a cell nucleus in which the genome is copied and separated into two identical halves. It is normally followed by cell division.
  • 2) The entire process of cell division including division of the nucleus and the cytoplasm.
  • 3) The process in cell division by which the nucleus divides, typically consisting of four stages, prophase, metaphase, anaphase, and telophase, and normally resulting in two new nuclei, each of which contains a complete copy of the parental chromosomes.
  • 4) (Biol.) See karyokinesis.
  • 5) cell division in which the nucleus divides into nuclei containing the same number of chromosomes
  • 6) Splitting of the chromatin of a nucleus, or subdivision of any minute granular bodies embedded in living protoplasm. The mitosis occurring in nuclear kinetics is commonly qualified as karyomitosis.
  • 7) A figure occurring during mitosis as a result of that process.

Definitions

  • 1) uncountable, cytology Cell division of a diploid cell into four haploid cells, which develop to produce gametes.
  • 2) countable, rhetoric A figure of speech whereby something is made to seem smaller or less important than it actually is.
  • 3) Genetics The process of cell division in sexually reproducing organisms that reduces the number of chromosomes from diploid to haploid, as in the production of gametes.
  • 4) Rhetorical understatement.
  • 5) (Cell Biology) The cellular process by which a diploid progenitor cell forms haploid gametes, including a division of one diploid cell into two cells, each with one of the homologous sets of chromosomes.
  • 6) (Rhet.) Diminution; a species of hyperbole, representing a thing as being less than it really is; understatement; see also litotes.
  • 7) (genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants)
  • 8) understatement for rhetorical effect (especially when expressing an affirmative by negating its contrary)

Examples

  • 1) Science keeps eddying into its past: the word mitosis—Greek for “thread”—is resonant here again.
  • 2) All life divided through mitosis, which is asexual reproduction, not female.
  • 3) The entire process of cell division, referred to as mitosis, takes only about an hour.
  • 4) In the simplest form of reproduction, one cell cutting itself in two to make two new ones, known as mitosis, the change begins in the nucleus, or kernel.
  • 5) Well, it was more about the way chromosomes get divided or doubled in two processes called mitosis and meiosis.
  • 6) (in a process called mitosis, depicted on the right), their genomes grow shorter until they reach a point where replication can no longer occur.
  • 7) ‘It is generally assumed that DNA chains are randomly segregated to daughter cells during mitosis.’
  • 8) ‘Centromeres are essential for the proper segregation of chromosomes at mitosis and meiosis.’
  • 9) ‘Counting cells at mitosis or interphase is universally applicable.’
  • 10) ‘Regions of the germline with cells in mitosis or different stages of meiotic prophase are indicated.’
  • 11) ‘The centromere is responsible for two key chromosomal functions in mitosis and meiosis.’

Examples

  • 1) Even in a prison setting, noted Lucy Durmast drily to herself, the habit of meiosis didn't desert the medical profession.
  • 2) You could imagine an egg that failed to divide during meiosis.
  • 3) My own mnemonic system depends on the fact that the word meiosis has been “reduced,” from mitosis, to the extent of not containing the letter t.
  • 4) Incorrect chromosome division during meiosis is the commonest cause of spontaneous miscarriage during pregnancy, and an extra chromosome 21 in humans leads to Down's syndrome.
  • 5) The process by which the DNA load is halved is termed meiosis.
  • 6) The process of gamete formation involves a specialized form of cell division called meiosis, which is tightly regulated by molecular processes within the cell.
  • 7) It’s possible the last time I heard the word meiosis was in my Anatomy and Physiology class in college.
  • 8) The transmission of genes from parent to offspring is carried out in a special process of cellular division called meiosis, which produces gamete cells containing one chromosome from each paired set.
  • 9) This is because when they form they discard half of their chromosomes in a process called meiosis.
  • 10) In cells undergoing the sexual cell division process called meiosis, there are lots of double-Holliday junctions and lots of crossovers.
  • 11) ‘In most meioses, every chromosome pair, no matter how small, sustains at least one crossover - a so-called obligate crossover or obligate chiasma.’
  • 12) ‘They were able to work with 12 meioses (a three-generational family with four grandparents, two parents, and four children) and seven marker loci.’
  • 13) ‘My personal hope is that students will have some intuitive understanding of meiosis as the physical basis of genetics.’
  • 14) ‘This is evidence that the genes are evolving in a concerted manner, as might be predicted for genes that mispair very frequently in meiosis.’
  • 15) ‘Models for genetic recombination have been proposed to explain the properties of genetic exchange during fungal meiosis.’
