Which statements are true? Explain why or why not.1 Since there are about 1013 cells in an adult human,and about 1010 cells die and are replaced each day, webecome new people every three years.2 In order for proliferating cells to maintain a rela-tively constant size, the length of the cell cycle must matchthe time it takes for the cell to double in size.3 While other proteins come and go during thecell cycle, the proteins of the origin recognition complexremain bound to the DNA throughout.4 Chromosomes are positioned on the metaphaseplate by equal and opposite forces that pull them towardthe two poles of the spindle.5 Meiosis segregates the paternal homologs intosperm and the maternal homologs into eggs.6 If we could turn on telomerase activity in all ourcells, we could prevent aging.
