- 1NucleusControls what happens inside the cell
- 2ChromosomesRod shaped bodies that contain DNA, found in the nucleus
23 pairs - 3DNA (Deoxyribonucleic Acid)Material carrying genetic information, found in the nucleus.
- 4GeneThe basic unit of genetic material, inherited from our parents.
A section of a chromosome - 5AlleleDifferent versions of the same gene
- 6OvariesPair of organs in the female reproductive system, producing eggs (ova) and sex hormones
- 7AntibioticsSubstances that kill bacteria
- 8Dominant (allele)An allele that expresses itself whether partnered with a recessive or another dominant allele.
- 9Recessive (Allele)An allele that is suppressed by a dominant one.
- 10Gene TherapyTreating/preventing disease by introducing/replacing specific genes
- 11EmbryoThe developing human offspring in the womb
- 12CloneAn organism that is genetically identical to it's parent
-bacteria, some animals
-plants - runners/plantlets/ug food storage organs - 13Homozygous2 of the same allele.
Either two recessive or two dominant. - 14HetrozygousTwo mismatching alleles.
Dominant+Recessive - 15GenotypeOur genetic make up
(combination of alleles) - 16PhenotypeA characteristic of an organism
- 17Asexual ReproductionNo sex, 1 parent=clone
-no fusion of gametes/genetic info - 18Enzymesbiological catalysts
- 19VariationDifference between individuals
(environmental or genetic) - 20Cystic Fibrosisrecessive

adult - develop into most
uses: brain cells, cartilage, bones, immune systems, heart valves - 32Therapeutic Cloningforeign cells-rejected
own cells-cloned -embryo-stem cells
nucleus from egg+n from patients cell, simulated to form embryo, contained w/warm nutrients, treated to develp as necessary - 33Embryo Transplantsdeveloping embryo removed, pre specialisation
cells seperated, grown, implanted
offspring-identical to eachother and original mother - 34Fusion cell cloningreplace nucleus of unfertilised egg (A) cell w/ another (B), implanted in 3rd
baby=identical to donor (B
