| Question? | Answer |
|---|---|
| Sexual reproduction | type of reproduction in which cells from two parents united to form the first cell of a new organism |
| Cell Division | the process by which a cell divides into two new "daughter" cells |
| Chromosomes | genetic information is bundled into packages of DNA |
| Chromatid | each DNA strand in the duplicated chromosome |
| Interphase | DNA replication |
| Mitosis | part of the eukaryotic cell division during which the nucleus divides |
| Centromere | region of a chromosome where the two sister chromatids attach |
| Centriole | structure in an animal cell that helps to organize cell division |
| Prophase | the replicated chromosomes become visible |
| Metaphase | chromosomes line up in the middle of the cell |
| Anaphase | chromsomes split up and move to opposite ends of the cell |
| Telophase | chromosomes begin to spread out |
| Cytokinesis | completes cell division |
| The process by which a cell divides into four daughter cells is called... | mitosis |
| An advantage of sexual reproduction over asexual reproduction is that sexual reproduction... | provides genetic diversity |
| Meiosis | process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell |
| Reproduction | is the process by which organisms produce offspring |
| What is it when two identical daughter cells are formed? | mitosis |
| G1 phase (gap) | cells increase in size and synthesize new proteins and organelles |
| S phase | new DNA is synthesize when the chromosomes are replicated |
| Binary fission | a cell splits into two parts |
| How many chromosomes do humans have? | 46 chromosomes |
| How many chromosomes do each parent pass of to their offspring? | 23 chromosomes |
| M phase | Mitosis and cytokinesis |
| Asexual reproduction | process of reproduction involving a single parent that results in offspring that are genetically identical to the parent |
