◉ Both mitosis and meiosis are preceded by
A) prometaphase
B) interphase
C) prophase
D) telophase. Answer: B) interphase
◉ Which of the following statements regarding the cell-cycle control
system is false?
A) The cell-cycle control system receives messages from outside the
cell that influence cell division
B) The cell-cycle control system triggers and controls major events
in the cell cycle
C) The cell-cycle control system includes three key checkpoints to
complete a cell cycle
,D) The cell-cycle control system operates independently of the
growth factors. Answer: D) The cell-cycle control system operates
independently of the growth factors
◉ Cancer is not usually inherited because
A) the chromosomal changes in cancer are usually confined to
somatic cells
B) people with cancer usually die before reproducing. Answer: A)
the chromosomal changes cancer are usually confined to somatic
cells
◉ Sister chromatids are
A) found right after a cell divides
B) joined together at a centromere
C) made only of DNA
D) unique to prokaryotes. Answer: B) joined together at a
centromere
◉ When animal cells are grown in a Petri dish, they typically stop
diving once they have formed a single, unbroken layer on the bottom
of the dish. This arrest of division is an example of
,A) cell constraint
B) density-dependent inhibition
C) cell division repression
D) growth factor desensitization. Answer: B) density dependent
inhibition
◉ The process by which the cytoplasm of a eukaryotic cell divides to
produce two cells is called
A) mitosis
B) cytokinesis
C) binary fission
D) telophase. Answer: B) cytokinesis
◉ Which of the following must occur for a plant or animal to grow
and develop normally?
A) The organism must receive a supply of the appropriate hormones
from its parents
B) The organism must be able to control the timing and rate of cell
division in different parts of its body
C) Sufficient light must be available to stimulate cell division
, D) Sufficient oxygen must be available to stimulate cell division.
Answer: B) The organism must be able to control the timing and rate
of cell division in different parts of its body
◉ With the exception of identical twins, siblings who have the same
two biological parents are likely to look similar, but not identical, to
each other because they have
A) identical chromosomes, but different genes
B) identical genes but different chromosomes
C) the same combination of traits, but different genes
D) a similar but not identical combination of genes. Answer: D) a
similar but not identical combination of genes
◉ Which of the following is a feature of plant cell division that
distinguishes it from animal cell division?
A) formation of a cell plate
B) formation of a cleavage furrow
C) lack of cytokinesis
D) production of four (rather than two) new cells per mitotic
division. Answer: A) formation of a cell plate
