Meiosis and Mitosis
Question | Answer |
---|---|
What type of cell undergoes meiosis? | Gamete Cells |
What are homologouse chromosomes? | Chromosomes that are the same |
Sperm Cell | Haploid |
Liver Cell D | Diploid |
Egg Cell | haploid |
Stomach Cell | Diploid |
If the diploid number in a liver cell is 52, how many chromosomes are there in the egg of this organism? | 26 |
During Meiosis, the chromosome number is: | Reduced |
Cells starting mitosis and meiosis begin with a (haploid or diploid) set of chromosomes. | Diploid |
How many times do cells divide during meiosis? | 2 |
What are the stages of meiosis I called? | Prophase I, Metaphase I, Anaphase I, Telophase I / Cytokinesis |
What about Meiosis II? | Prophase II, Metaphase II, Anaphase II, Telophase II / Cytokinesis II |
What phase do you first see a tetrad in? | Prophase |
What best describes the term "crossing over"? | An exchange of information between two homologous chromosomes |
Crossing over can be found in the stage of | Prophase I and Metaphase I |
Is DNA copied before Meiosis II? | Yes because DNA replication happens in Interphase S and that is before any other phases. |
How many cells form at the end of Meiosis II and how many chromosomes do they contain | 46 cells and 23 chromosomes |
A Sperm cell is a (gamete, zygote), and is (haploid, diploid). and why? | Gamete and Haploid because all sex cells are haploid and body cells are diploids |
When a sperm cell and an ovum/egg merge, they undergo the process of fertilization, and give rise to a (gamete, zygote), which is (haploid, diploid). | Gamete and Haploid |
What is the ultimate goal/purpose of mitosis? What term do we use to describe the new cells? | Division of somatic cells. Daughter cells |
Describe Cancer | uncontrolled Cell Division |
How are DNA and chromosomes related? | DNA is a double-helix that contains chromosomes |
What is a gamete? How do we represent the chromosome number: 2n or n? | A gamete is a sex cell and it is represented by n |
What is crossing over? When does it happen? | Crossing Over is when sister chromatids swap pieces of their chromosomes. Prophase I and Metaphase I |
OOGenesis | the production of an egg |
Chromosomes |
