Biology b checkpoint 12

WebWhen a cell’s DNA is damaged, a sensor protein activates p53, which halts the cell cycle at the G 1 _1 1 start subscript, 1, end subscript checkpoint by triggering production of a cell-cycle inhibitor. This pause buys time for DNA repair, which also depends on p53, whose second job is to activate DNA repair enzymes. WebImmune checkpoints are regulators of immune activation. They play a key role in maintaining immune homeostasis and preventing autoimmunity. In cancer, immune checkpoint mechanisms are often activated to suppress the nascent anti-tumor immune response. This has led to the development of several checkpoint inhibitor antibody …

WebIn eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells. Web23. Eukaryotic chromosomes are thousands of times longer than a typical cell. Explain how chromosomes can fit inside a eukaryotic nucleus. The genetic material remains distributed in the nucleus, mitochondria, and chloroplast. The genome is present in a looped structure, thus it fits the size of the nucleus.
