- for each phase of mitosis make sure you can describe the events that take places as well as the mechanism(I.e from where to do microtubles form? How do they attach? What proteins are involved in chromosomes condensation? Etc)1 3 4 Here is a replication fork during S phase of the cell cycle. DNA strands are labeled 1-4. After mitosis and cytokinesis is complete, One daughter cell will have strands 18&2, another will have strands 3&4 One cell will have 1&3, the other will have 2&4 Each of the strands (1-4) will be in a different cell. All four strands will end up in the same cell, and the other cell will have the complementary strands. Both A and B are equally likely.Mitosis and Cell Division – Location 3 Seek out and define: Seek out the best (clearest, most obvious, etc.) example of mitosis or cell division you can find online. Once you have found your image, write a single sentence that explains what's going on in your picture. This picture needs to be really good so don't just choose the first image you find. Be picky and find something that really stands out for full marks. Locate the picture, take a screenshot and upload it to your submission form along with your sentence. If you're not submitting online, show the picture to your teacher.
- Chromatin fibers composed of roughly equal amounts of DNA and protein molecules make up the chromosomes where the protein molecules help organize the chromatin and help control the activity of its genes. Select one: True FalseWhich of the following statements is TRUE? O Interphase chromosomes are loosely compacted, overlapping, and intertwined with each other within the nucleus. O Interphase chromosomes are loosely compacted and do not associate with histones until the cell is preparing to divide. O Interphase chromosomes are also known as euchromatin. Condensed, metaphase chromosomes are also known as heterochromatin. O Radial loops in the condensing chromosome are formed due to interactions between 30 nm fibers and the scaffolding proteins of the nuclear matrix - producing the 300 nm fiber of the chromosome O None of these are TRUEE Samu E Samu FAIPQLSCDH_No2]MEaHUdrt5NWa2uY6AaKa7Bhy4xfhwplF-CsVAbyA/formResponse Gmail YouTube O Maps Which model below accurately depicts the process of mitosis? * 2n 2n 2n Option 1 Option 2 2n 2n 2n 2n Option 4 Option 3

Can you identify it? • Is cell of sufficient size? • Have proper signals been received? THEN: Duplicate chromosomes and centrosomes Ongoing protein synthesis and cell growth Chromosome and centrosome duplication Interphase Telophase and cytokinesis Mitosis Anaphase • Have the chromosomes been completely duplicated? THEN: Enter mitosis Prophase Metaphase • Have all chromosomes arrived and aligned at the metaphase plate? THEN: Initiate anaphase
