Answer: amino acids
Edpuzzle Meiosis Answers Key
Here is the Edpuzzle answers key to the topic Meiosis:
- Question: How many cells are produced by meiosis?
- Question: What is happening during Prophase I?
Answer: Homologous chromosomes pair up and crossing over occurs.
- Question: What is recombination and why is it important?
Answer: Some of the genetic material is swapped between the two chromatids, now the chromosomes are a mixture of the DNA from the two parents. This is important as it leads to genetic diversity.
- Question: What has formed at the end of meiosis I?
Answer: 2 daughter cells
- Question: True or False – The DNA replicates again right before meiosis II.
- Question: Describe the cells which are formed at the end of the process of meiosis
Answer: 4 cells, which are genetically different, and each hold half the amount of DNA of the original cell
- Question: How many Chromosomes do humans have?
- Question: When a cell contains two sets of chromosomes, one from the mother and one from the father, it is called
- Question: When a cell contains only one of each chromosome, there are no partners, this is called
- Question: What is the haploid number for humans?
- Question: What type of cells does mitosis make?
Answer: body cells like skin and stomach cells
- Question: In which phase do your cells replicate your chromosomes?
- Question: When 46 chromosomes replicate, how many chromatids are there?
- Question: Mitosis produces _______ cells while meiosis produces _______ cells.
Answer: 2 diploid; 4 haploid
- Question: What are homologous chromosomes?
Answer: Chromosomes that are similar in size to each other and have similar traits at the same location on each chromosome. One comes from mom, other from dad.
- Question: During which phase of Meiosis does crossing-over occur?
Answer: prophase 1
- Question: What does crossing over of homologous pairs or homologous chromosomes do to siblings with the same parents?
Ans: Causes genetic variation in which siblings look different from each other
- Question: How are the chromosomes arranged differently in Metaphase I (meiosis) compared to Metaphase during mitosis?
Answer: In Metaphase I, homologous chromosomes are paired up in the center of the cell
- Question: After Meiosis I, the end result is
Answer: Two cells that each have half the number of chromosomes they started with
- Question: Prophase II is not as eventful as Prophase I because
Answer: crossing over does not occur
- Question: Look at the chart and the cells. You started with one cell with 46 chromosomes. What is the product of meiosis?
Answer: 4 cells with 23 chromosomes
- Question: Which events during meiosis increase genetic variation by ensuring that each egg and each sperm will be unique? Mark 2.
Answer: crossing over & independent assortment
- Question: What is the term for incorrect separation of chromosomes?
- Question: When can you see chromosomes?
Answer: only when they are in their condensed form
- Question: If you have a cell with 46 chromosomes and it replicates its chromosomes before cell division, how many chromosomes do you now have in the cell?
- Question: In anaphase sister chromatids get pulled apart. How many chromosomes are now present in the cell?
- Question: Before meiosis occurs, what must happen with the DNA?
Answer: DNA replication will occur
- Question: How many cell divisions occur with Meiosis?
Answer: 2 (Meiosis I and Meiosis II)
- Question: What happens to the chromatin in Prophase I?
Answer: Chromatin condenses into discrete chromosomes
- Question: What will happen to the centrosomes in Prophase I?
Answer: The pair will go to the opposite poles of the cell
- Question: What is another word for a homologous chromosome?
- Question: During Prophase I, what happens when crossing over occurs at the chiasmata between homologs or homologous chromosomes?
Answer: The crossing over leads to genetic variation due to exchanging genetic material between the homologous chromosomes
- Question: What happens during Anaphase I?
Answer: The homologous chromosomes separate
- Question: What happens during Telophase I?
Answer: The DNA decondense, the nuclear membrane reforms, and the cytoplasm divide. Homologous chromosomes separate from each other and go to opposite ends of the cell.
- Question: During Metaphase II. what lines up at the equatorial plate?
Answer: Sister chromatids of a chromosome
- Question: During Telophase II, what happens?
Answer: Nuclear membrane reforms result in decondensed chromosomes, and the cytoplasm divides.
