CELL DIVISION-SBOT
| Terms | Definitions |
|---|---|
| traits | characteristics |
| inherited | trait that is passed from parents to offspring |
| zygote | fertilized egg |
| genetics | study of heredity |
| meiosis | type of cell division that produces gametes |
| gametes | reproductive cells |
| stem cell | cells that are undifferentiated |
| differentiation | process where cells are changed into a specific blood cell, tissue cells, etc. |
| sex cells are produced during this process | meiosis |
| replication | process by which DNA is duplicated |
| RNA | molecule used in the making of proteins |
| How many cells does meiosis produce | 4 |
| centromere | point of a CHROMOSOME WHERE TWO PARTS MEET |
| gene | parts of a chromosome that control the inherited traits |
| allele | one of the two or more forms of a particular gene |
| homozygous | have two like genes for the same trait |
| heterozygous | having two unlike genes for the same trait |
| dominant gene | gene whose trait always shows itself |
| recessive gene | gene of a trait that is hidden when the dominate gene is present |
| Number of chromosomes in the nucleus | 46 |
| phenotype | physical showing/expression of a trait |
| genotype | genetic make up of a trait |
| interphase | resting state of a normal cell |
| prophase | stage where chromosomes condense and become visible |
| metaphase | stage where nucleus disappears and chromosomes line up |
| anaphase | stage where chromosomes seperate to opposite ends of the cell |
| telophase | stage where nucleus forms in each new cell, final stage of mitosis or meiosis |
| number of chromosomes inherited from each parent during reproduction | 23 |
| centrioles | small cylindrical cell organelle that helps cell divide in a perpendicular fashion during mitosis |
