| Question | Answer |
| Nucleusi | Cell part that contains chromosomes |
| Deoxyribonucleic Acid | DNA Substance carrying organism's genetic information |
| Chromosome | Threadlike structure of DNA and prtein found in the nucleus of cells - carries the genetic information in the form of cells |
| Homologous Chromosomes | Having the same structural features (length) and pattern of genes |
| Karyotype | Photograph of an individuals chromosomes cut out and arranged according to their size |
| Gene | Short length of DNA that carries the genetic code for a particular trait/characteristic or cell activity |
| Base | Parts of DNA involved in pairing - cytosine, guanine, adenine and thymine |
| Nucleotide | Forms the basic structural unit of DNA, composed of a sugar molecule, a phosphate group and a base |
| DNA | Carries instructions to the next generation and determines the phenotype |
| Trait | A genetically determined characteristic |
| Variation | Differences between organisms within a population - can be continuous or discontinuous |
| Mitosis | Cell division in the body cells for growth and repair - produces 2 new cells genetically identical to each other and to the parent |
| Meiosis | Cell division in the testes and ovaries producing 4 new cells (gametes) - genetically different to each other, and to the parent cell |
| Gamete | Reproductive cells that contain half the number of chromosomes compared to the parent cell |
| Zygote | A fertilised ovum/egg that contains the full set of chromosomes |
