| Term | Definition |
|---|---|
| mitosis | cell divide of body cells |
| cytokinesis | Cytokinesis is the process during cell division in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells. |
| replication | the process of producing two identical replicas from one original DNA molecule. |
| 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. |
| 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 | containing two complete sets of chromosomes, one from each parent. |
| 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 tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids |
| synapsis | s the pairing of two homologous chromosomes that occurs during meiosis |
| polar bodies | A polar body is a small haploid cell that is formed concomitantly as an egg cell during oogenesis, but which generally does not have the ability to be fertilized |
| gametogenesis | the process in which cells undergo meiosis to form gametes. |
| gonad | The gonads are the reproductive organs for both males and females |
| 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. |
| ovum/ova | is the name for the haploid female reproductive cell, or gamete. |
| sperm | Sperm is the male reproductive cell |
| hapliod | having a single set of unpaired chromosomes |
