During mitosis, the eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. Mitosis progresses through five separate morphologically distinct phases. Name, in order, these five phases of mitosis. Answer : Prophase, prometaphase, metaphase, anaphase, and telophase....
Tissues are constructed from many distinct cell types that perform different functions in response to signals from each other and the extracellular matrix. During tissue development and tissue regeneration, ... that stem cells undergo when they are required to generate a particular type of cell? Answer : Asymmetric cell division. After asymmetric division, each of the two resulting daughter cells has a unique life course. For example, one daughter cell may differentiate into a specific cell type ( ... cell), whereas the other daughter cell may remain a stem cell with unlimited proliferative ability....
Eukaryotic cells have extensive intracellular membranes, termed the endomembrane system, which divide the cell into structurally and functionally distinct compartments, or organelles. These include the inner cell ... . Name a cellular component whose membrane is not part of the endomembrane system. Answer : Mitochondria; also chloroplasts...
In many types of cancer, proteins that are crucial regulators of the cell cycle are often mutated and cannot function correctly. This leads to the evasion of apoptosis and to the loss of control of cell ... protein named p53. What is the normal function of p53 that is lost when it is mutated? Answer : Normally, p53 senses DNA damage and acts as a transcription factor for checkpoint control genes....
At the beginning of which phase of mitosis does each duplicated and condensed chromosome consisting of two identical sister chromatids align along the cell equator? Answer : Metaphase...
