When during the cell cycle are chromosomes visible?
only during interphase
only when they are being replicated
only during the G1 phase
only during cell division
One difference between cell division in plant cells and in animal cells is that plant cells have
centrioles
centromeres
a cell plate
chromatin
Cytokinesis occurs when a cleavage furrow forms in
animal cells
plant cells
plant and animal cells
all cells
When during the cell cycle is a cell’s DNA replicated?
G1 phase
G2 phase
S phase
M phase
During normal mitotic cell division, a parent cell having eight chromosomes will produce two daughter cells, each containing
2 chromosomes
4 chromosomes
8 chromosomes
16 chromosomes
Which event occurs during interphase?
The cell grows.
Centrioles appear.
Spindle fibers begin to form.
Centromeres divide.
The process by which a cell divides into two identical daughter cells is called
replication
interphase
meiosis
mitosis
The two main stages of cell division are called
mitosis and interphase
the M phase and the S phase
synthesis and cytokinesis
mitosis and cytokinesis
The cell cycle is the
series of events that cells go through as they grow and divide
period of time between the birth and the death of a cell
time from prophase until cytokinesis
time it takes for one cell to undergo mitosis
In DNA replication, the enzyme that unwinds and unzips the DNA double helix is called
unzipase
DNA polymerase
helicase
replicase
The functional building block of DNA molecules called a
chromosome
nucleotide
base pair
histone

In order to fit within a cell, DNA becomes more compact by
breaking apart into separate genes.
extending to form very long, thin molecules
wrapping tightly around histone proteins
being enzymatically changed into a protein
What is the end product of meiosis?
two identical daughter cells
four identical daughter cells
two nonidentical cells with ½ DNA
four nonidentical gamete cells
Two identical copies of a chromosome, held together by a centromere are called
sister chromatids
sister chromatin
haploid
homologous pairs
In what stage of meiosis do sister chromatids separate?
Anaphase I
Anaphase II
cytokinesis
telophase
The phase of mitosis where chromosome condense and the mitotic spindle forms is called
prophase
anaphase
telophase
metaphase
What base pairs complement this sequence: ACTGA
ACTGA
TCAGT
TGACT
