The component of the cytoskeleton that attaches to the chromosomes in order to pull and separate them is the
answer
mitotic spindle.
question
The structure that organizes the protein subunits of the mitotic spindle is the
answer
centromere.
question
The phase of mitosis in which the nuclear envelope breaks into small pieces is
answer
prophase.
question
The phase of mitosis in which the centromeres split and sister chromatids are pulled to opposite poles of the cell is
answer
anaphase.
question
The phase of mitosis in which the chromosomes are aligned along the equator of the cell is
answer
metaphase.
question
The phase of mitosis in which the nuclear envelope begins to reform around chromosomes is
answer
telophase.
question
The phase of mitosis in which the chromosomes condense and centrosomes move to opposite poles of the cell is
answer
prophase.
question
The first sign of cytokinesis in an animal cell is the formation of a
answer
cleavage furrow.
question
The first sign of cytokinesis in a plant cell is the formation of a
answer
cell plate.
question
In an asexual life cycle, cells reproduce by
answer
mitosis.
question
In a sexual life cycle, a zygote (fertilized egg) grows to an adult by
answer
mitosis.
question
How does the space between our fingers arise?
answer

answer
3' AGGCCG 5'.
question
if a mutation causes the "G" base in the base sequence 5' AATGAC 3' to be read as a "T" base, DNA replication of the mutated sequence will read
answer
3' AATTAC 5'.
question
When DNA replicates
answer
one strand of the original DNA ends up in each of the new DNA molecules.
question
A cell condenses its DNA into ______ in preparation for mitosis.
answer
chromosomes
question
The chemotherapy drug taxol inhibits microtubule function. A cell treated with taxol would become stuck in which phase?
answer
prophase
question
Why don't plant cells form a cleavage furrow during cytokinesis?
answer
because they have a cell wall
question
An asexual process used by prokaryotes in which replicated DNA and other cell parts are distributed into two daughter cells is called
answer
binary fission.
question
Which of the following is correct about both binary fission and mitosis?
answer
Both are asexual forms of cell reproduction.--Both result in genetically-identical cells.--Both replicate the DNA before the cell splits.--Both result in two daughter cells.
