| Question | Answer |
|---|---|
| A method of sexual reproduction in which a cell splits in two. | Binary fission |
| The resting phase between mitosis divisions of a cell or between the first and second division of meiosis. | Interphase |
| First stage of mitosis, during which the cells chromatin condenses into chromosomes. | Prophase |
| Second stage of mitosis in which motor proteins pull sister chromatids to the center of the cell | Metaphase |
| Third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell. | Anaphase |
| Last stage of mitosis in which the nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided. | Telophase |
| Organelle that plays a role in cell division and is made of microtubules. | Centriole |
| Relaxed form of DNA in then nucleus of a cell. | Chromatid |
| Exchange of chromosomal segments between a pair of homologous chromosomes during prophase one of meiosis. | Crossing over |
| DNA containing structure that carries genetic material from one generation to another. | Chromosome |
| Form of reproduction used by some prokaryotes in which prokaryotic cells attach to eachother and exchange genetic material. | Conjugation |
| Having two copies of each chromosome. | Diploid |
| A haploid sex cell, formed during meiosis, that can combine with another haploid cell and produce a diploid fertilized egg. | Gamete |
| A variety of inheritable characteristics or genes in an interbreeding population. | Genetic variations |
| Cell with half of the number of chromosomes as a diploid cell. Homologous chromosome - 1 of 2 pairs of chromosomes, one from each parent, that carries genes for a specific trait at the same location. | Haploid |
| Reduction division process, occurring only in reproductive cells, in which the diploid cell produces four haploid cells that are not genetically identical. | Meiosis |
| Second main stage in the cell cycle during which the cells replicated DNA divides and two genetically identical diploid daughter cells are produced. | Mitosis |
| Permanent change in a cells DNA ranging from changes in a single based pair to deletions of large sections of chromosomes. | Mutation |
| Newly generated DNA fragment containing exogenous DNA. | Recombination |
| Idea that life arrives from nonliving things. | Spontaneous generation |
| Fertilized egg formed when a sperm cell penetrates an egg. | Zygote |
| Explains that eukaryotic cells may have evolved from prokaryotic cells. | Endosymbosis |
