| 5974801188 | model organism | organism choosen for study |  | 0 |
| 5974801189 | embryonic development | gives rise to cells of different types and higher level structures |  | 1 |
| 5974801190 | cell division | many mitotic cell devisions, the zygote gives rise to a large number of cells |  | 2 |
| 5974801191 | cell differentiation | cells become specialized in structure and function |  | 3 |
| 5974801192 | morhogenesis | the biological process that causes an organism to develop its shape |  | 4 |
| 5974801194 | totipotent | describing a cell that can give rise to all parts of an organism |  | 5 |
| 5974801195 | somatic cells | any cells that are not your sex cells |  | 6 |
| 5974801196 | cloning | making a geniticall identical individual |  | 7 |
| 5974801197 | nuclear transplantation | removes the nucleus of an infertilized eff cell or zygote and replace it with the nucleus of a differentiated cell |  | 8 |
| 5974801199 | reproductive cloning | the goal to reproduce new indivuals |  | 9 |
| 5974801200 | stem cell | unspecialized cell that can divide during a single division into one identical daughter cells |  | 10 |
| 5974801201 | therapeutic cloning | when a major aim of cloning is to produce embryonic stem cells to treat disease |  | 11 |
| 5974801202 | cell determination | stem cells become committed to develop into only one type of cell |  | 12 |
| 5974801204 | cytoplasmic determinants | maternal substances in egg that influence the course of early development. |  | 13 |
| 5974801206 | embryonic lethal | mutations with phenotype causing death at the the embryonic or larval stage |  | 14 |
| 5974801208 | segmentation genes | gap genes, pair rules genes, segment polarity |  | 15 |
| 5974801209 | homeotic genes | the anatomical identity of the segments is set by this master regulatory gene |  | 16 |
| 5974801210 | transcriptional regulation | turning off and on of specific genes |  | 17 |
| 5974801211 | cell lineage | the ancestry of a cell |  | 18 |
| 5974801212 | cell signaling | helps direct daughter cells down the appropriate pathways |  | 19 |
| 5974801213 | apoptosis | programmed cell death |  | 20 |
| 5974801214 | chimera | organism with a mixture of genetically different cells |  | 21 |
| 5974801215 | organ identity genes | plant homeotic genes that use positional information to determine which emerging leaves develop into which tpes of floral organs |  | 22 |
| 5974801216 | homeobox | 180 nucleotide sequence withing homeotic genes and some other developmental genes that is widely conserved in animals |  | 23 |
