CORRECT ANSWERS
◉ Which represents the correct sequence of stages in the cell cycle?
Answer: G1, S, G2, M
◉ The event that signals the start of anaphase is
Answer: division of the centromeres to separate sister chromatids.
◉ Which does NOT occur in telophase?
Answer: The centromeres split apart.
◉ The purpose of therapeutic cloning is
Answer: to produce specialized tissue cells.
◉ Which stage is most associated with a cell that is unable to divide
again, such as a muscle or nerve cell?
Answer: G0 phase
◉ What occurs in anaphase?
Answer: Chromosomes move to opposite poles.
, ◉ Apoptosis
Answer: a.is programmed cell death.
b. is a process that acts to decrease the number of somatic cells.
c. frees the fingers and toes of the human embryo from their
'webbed' structure to independent structures.
◉ Binary fission in bacteria differs from mitosis because
Answer: a. the chromosome copies attach to the plasma membrane
and are pulled apart by cell growth.

◉ Which is NOT true about the chromosomes of a multicellular
organism?
Answer: Each chromosome separates into two daughter
chromosomes by binary fission.

will each daughter cell have after mitosis and cytokinesis occurs?
Answer: 48 chromosomes
