Meiosis
| Question | Answer |
|---|---|
| The process of cell division in sexually reproducing organisms that reduces the number of chromosomes in reproductive cells from diploid to haploid, leading to the production of gametes in animals and spores in plants. | meiosis |
| what is the first phase of meiosis called | G1 stage |
| What is the second stage of meiosis called | S stage |
| what is the third stage of meiosis | G2 stage |
| what is anaphase 1 | begins with the separation of the Tetrads at the sites of crossing over Achieved through the use of relatively powerful molecular motors on the Kinetochores |
| What is prophase 1 | The Chromatin fibres coil and fold together forming several Chromosomes |
| what is interphase | consists of three smaller phases called |
| what is Cytokinesis | the process whereby the cytoplasm of a single cell is divided to spawn two daughter cells |
| what is prophase 2 | the Centrosomes move away from each other using molecular motor proteins while rapidly extending microtubules which meet between the two. |
| what is metaphase 2 | the spindle is fully formed, having poles at both ends of the cell |
| what is anaphase 2 | the Chromosome is finally split in two identical sister Chromosomes this is done with molecular motors on the Kinetochores |
| what are Phases G1 and G2 short for | “First Gap” and “Second Gap” |
| what begins to reform at the end of telophase 2 | The Nuclei |
| what is Cytokinesis | single cell is divided to spawn two daughter cells |
| What is the second stage of meiosis called | S stage |
| what is interphase | consists of three smaller phases called |
| after the cell has finishes the m2 phase what is its job | to rebuild and start the cycle all over again. |
| what is prophase 2 | extending microtubules which meet between the two. |
| what is the third stage of meiosis | G2 stage |
| what are Phases G1 and G2 short for | “First Gap” and “Second Gap” |
| true or false the s phase is the first phase of mitosis | false |
| true or false the first stage of mitosis is the G1 stage | true |
| what is interphase | consists of three smaller phases called |
| what begins to reform at the end of telophase 2 | The Nuclei |
| what is the third stage of meiosis | G2 stage |
