|---|---|---|---|---|---|
| citokinesis | the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.
🗑
|
||||
| Replication | the action of copying or reproducing something.
2.
LAWdated
a plaintiff's reply to the defendant's plea.
🗑
|
||||
| Cell cycle | The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells.
🗑
|
||||
| chromosomes | a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
🗑
|
||||
| chromatid | each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.
🗑
|
||||
| centromere | the point on a chromosome by which it is attached to a spindle fiber during cell division.
🗑
|
||||
| gametogenesis | the process in which cells undergo meiosis to form gametes.
🗑
|
||||
| gamete | a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
🗑
|
||||
| sperm | a male reproductive cell; spermatozoon.
🗑
|
||||
| chromatin | the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA.
🗑
|
||||
| diploid | 1.
(of a cell or nucleus) containing two complete sets of chromosomes, one from each parent.
noun
1.
a diploid cell, organism, or species.
🗑
|
||||
| interphase | the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
🗑
|
||||
| crossing over | the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring.
🗑
|
||||
| tetrad | a group or set of four.
🗑
|
||||
| synapsis | the fusion of chromosome pairs at the start of meiosis.
🗑
|
||||
| polar vodies | each of the small cells that bud off from an oocyte at the two meiotic divisions and do not develop into ova.
🗑
|
||||
| gonad | an organ that produces gametes; a testis or ovary.
vulgar slang
a man's testicles or genitals.
🗑
|
||||
| ovum/ova | a mature female reproductive cell, especially of a human or other animal, that can divide to give rise to an embryo usually only after fertilization by a male cell.
🗑
|
||||
| haploid | (of a cell or nucleus) having a single set of unpaired chromosomes.
noun
1.
a haploid organism or cell.
🗑
|
||||
| mitosis | a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
