Meiosis\Mitosis
Meiosis
| Question | Answer |
|---|---|
| During which stage are homologous pairs of chromosomes lined up on the equator of the cell? | Metaphase |
| Chromosomes replicate during this phase | interphase |
| Genes replicate during this phase | interphase |
| DNA replicates during this phase | interphase |
| Condensation and shortening of chromosomes occurs during this phase | prophase |
| cytokineses occurs as this phase of mitosis proceeds | telophase |
| new daughter nuclear membranes form during this phase | telophase |
| each chromosome is separated from its homologue and moves to the opposite poole | anaphase 1 |
| two parcels of chromosomes | prophase 1 |
| sister chromatids of each chromosome are separated and move to opposite poles | anaphase 2 |
| homologues pair with each other and crossing over can occur | metaphase 2 |
| pairs of homologous chromosomes align randomly at the spindle equator | metaphase 1 |
| All cells come from... | preexisting cells |
| Mitosis can | increase the number of body cells without changing the information contained in the DNA of those cells |
| Chromatic | a dense substance within the nuclear membrane of a non dividing cell |
| When all of the chromosomes are arranged along the equator of a cell, the cell is said to be in | metaphase |
| Sexual reproduction | results in new combinations of genetic traits |
| Gamete formation is | the formation of sex cells |
| Crayfish have a diploid number of 200. What cells would have 200 chromosomes | nerve cell |
| Mitosis is not used for | production of gametes |
| Asexual reporduction is not | fertilization |
| The nucleus of a cell divides by | mitosis |
| Prokaryotic organisms divide by | fission |
| Cytokinesis in plants is noted by | cell plate formation |
| Chromosomes of individuals can be photographed and orgainzed onto a picture called a | karyotype |
| Asexually reproduced daughter cells are | identical to each other and identical to the mother cell |
| In mitosis, if a parent cell has 16 chromosomes , each daughter cell will have how many chromosomes? | 16 |
| In meiosis if a parent cell has 16 chromosomes each daughter cell will have how many chromosomes? | 8 |
| The term, Mitosis, is derived from a Greek work mitos which means | thread |
| Gametogenesis in female animals results in | one gamete and three polar bodies |
| A daughter chromosome | is formed during anaphase2 and is the results of separation of chromatids |
| DNA duplication occurs during | interphase |
| Interphase is not | nuclear division |
| Meiosis typically results in the production of | 4 haploid cells |
| Asexuall reproduction does not produce | variation |
| Gamete formation is | the formation of sex cells |
| Gamete does not concern cells with | two crhomosome sets |
| primary spermatocyte does not describe | haploid cells |
