A centriole is an organelle that is _
present in the center of a cell’s cytoplasm
composed of microtubules and important for organizing the spindle fibers
surrounded by a membrane
part of a chromosome
composed of microtubules and important for organizing the spindle fibers
Which cell cycle checkpoint determines whether the DNA has been replicated correctly?
the mitosis checkpoint
the G2 checkpoint
the DNA synthesis checkpoint
the cell growth checkpoint
the G2 checkpoint
Why is it necessary for the DNA to replicate prior to cell division?
so that each daughter cell will have 2 sister chromatids
so that each daughter cell will have 46 homologous chromosomes
so that each daughter cell will have a complete copy of the genetic material
so that each daughter cell will have 23 chromosomes
so that each daughter cell will have 2 sister chromatids
Most routine metabolic processes occur during which phase of the cell cycle?
growth phase 1
Mitosis
growth phase 2
Interphase
growth phase 1
Why do chromosomes have an X-shape?
because they are made of two sister centromeres
because they are made of two sister chromatids
because they are made of two sister chromatins
because they are made of two sister chromosomes
because they are made of two sister chromatids
