- S. Chromosomes are duplicated during what stage of the cell cycle? G1 phase S phase prophase prometaphaseFigure 10.6 Which of the following is the correct order of events in mitosis? Sister chromatids line up at the metaphase plate. The kinetochore becomes attached to the mitotic spindle. The nucleus reforms and the cell divides. Cohesin proteins break down and the sister chromatids separate. The kinetochore becomes attached to the mitotic spindle. Cohesin proteins break down and the sister chromatids separate. Sister chromatids line up at the metaphase plate. The nucleus reforms and the cell divides. The kinetochore becomes attached to the cohesin proteins. Sister chromatids line up at the metaphase plate. The kinetochore breaks down and the sister chromatids separate. The nucleus reforms and the cell divides. The kinetochore becomes attached to the mitotic spindle. Sister chromatids line up at the metaphase plate. Cohesin proteins break down and the sister chromatids separate.

Peak B Peak A number of cells 0 The area in between A and B Both A and B peaks A B relative amount of DNA per cell
- Which of the following statements regarding cyclin B is FALSE? Group of answer choices It is a component of the mitosis or maturation promoting factor (MPF) Its production and activation is linked to extracellular stimuli It interacts and activates CDK1 protein kinase Its destruction by APC/C signals the end of mitosis All of the above are trueThe diagram below shows a model for the normal regulation of the transition to anaphase during mitosis. 1. Signals are released by unattached kinetochores that cause MAD to bind CDC20. MAD CDC20 6. Chromatids separate as mitosis procoeds to anaphase. COHESIN 3. The APCCDC20 CDC20 complex ubiquinates Securin. APC 2. When all kinetochores are attached, MAD releases CDC20 which then combines with APC UBIQUITIN SEPARASE . Separase destroys Cohesin APC SEPARASE SECURIN 4. Securin is destroyed, releasing Separase Your analyses of cancer cells that do not regulate this transition normally indicate that: MAD is binding to CDC20; • Ubiquitin is not attached to securin; • Sister chromatids separate and move to opposite poles of the cell. Which of the following explanations could account for all of your observations? a. The cell has an alteration in MAD that prevents it from releasing CDC20 when the 'unattached kinetochore' signal stops. O b. More than one of the other answer choices are correct.…Which of these describes the genetic material of cells produced by mitosis? Select ali at apply. ONew cells have half the number of chromosomes as the original cell O New cells are genetically identical to the original cell New cells have the same number of chromosomes as the original cell ONew cells have the same number of chromosomes as the original cell but have different genes
- Choose all of the TRUE statements. Hint: 4 statements are true. Cytokinesis occurs the same way in both plant and animal cells. Sister chromatids are genetically identical. The term chromosome can be used to describe both chromosomes composed of one and two chromatids. Mitosis results in daughter cells that are genetically identical to the parent cell. All eukaryotic somatic cells are diploid. Cyclin dependent kinases are present but not active in cell cycle regulation without the presence of cyclin proteins. Chromosomes are always visible in the cell.When considering the stages of the cell cycle, which stage is best associated with cells that do not divide, such as nerve cells? G1 phase M phase O None - all cells divide S phase G2 phase GO phase Pickles are often preserved in a 20-30% salt solution called brine. How does brine prevent contamination by microorganisms? Bacteria can't survive in hypotonic solutions because of the added pressure of the water they take in causing them to burst. O Bacteria can't survive in a hypertonic solution because they lose too much water and die. O The high salt concentration increases the pH of the environment, making it unfavorable for bacteria to live there. The high salt concentration creates an isotonic environment that the bacteria cannot live in. Bacteria cells are unable to digest the salt, thus killing the cells by starvation.Which of the following is NOT correct answer about telophase of mitosis: The mitotic spindle is formed in this phase Two new nuclei form, and two sets of chromosomes Nuclear membrane and nucleoid reappear in this phase The enzyme aminoacyl TRNA synthetase charges the TRNA molecules with the correct amino acids FRNA molecules with the correct amino acids MRNA molecules with the correct amino acids
