A cell entering mitоsis hаs cоmpleted DNA replicаtiоn аnd has 46 chromosomes (human somatic cell). At metaphase, all chromosomes are aligned at the metaphase plate with sister chromatids attached at the centromere. However, the M checkpoint detects that one chromosome's kinetochore is not properly attached to spindle fibers from both poles. Meanwhile, a Rb protein mutation allows the cell to bypass the G1 checkpoint. What is the most likely outcome?
