Biology b checkpoint 15
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. 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.
