Meiosis and Mitosis

QuestionAnswer
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
