| Term | Definition |
|---|---|
| DNA | Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. |
| Chromosomes | A chromosome is a long DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins called histones which, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its i |
| Cell cyckel | The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells. |
| Interphase | Intrphase is the portion of the cell cycle that is not accompanied by observable changes under the microscope, and includes the G 1, S and G 2 phases. During intrphase, the cell grows, replicates its DNA and prepares for mitosis. |
| Mitosis | In cell biology, mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained. |
| Cytoknetienets | Relating to the division of the cytoplasm of a cell following the division of the nucleus. |
| Homologous | In biology, homology is similarity due to shared ancestry between a pair of structures or genes in different tax. |
| Meiosis | a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores. |
| Ashreckal reproduction | Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of |
| shreckal reproduction | Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete with a single set of chromosomes combines with another to produce an organism composed of cells with two sets of chromosomes. |
| Fertlizaton | Fertilisation or fertilization, also known as generative fertilisation, syngmay and impregnation, is the fusion of gametes to give rise to a new individual organism or offspring and initiate its development. |
