BIO 1108 EXAM QUESTIONS AND
ANSWERS A+ GRADED
During interphase of meiosis, homologous chromosomes are replicated.
true
Cells that have two sets of chromosomes (2n) are
diploid
To yield haploid cells, in meiosis II, the parent and daughter DNA separate.
false (sister chromatids separate)
During meiosis, there is only 1 cellular division.
false
Errors in meiosis are the cause of chromosomal abnormality. This is known as
nondisjunction.
true
The following figure is an example of an onion cell undergoing what stage in
mitosis?
anaphase
Most of your cells contain 46 chromosomes. You inherited 23 from your mother
and 23 from your father. Before cells divide, each of them condense into an X
shaped duplicate chromosome, which can be seen with the light microscope. At
this stage, each chromosome contains,
The daughter cells of meiosis are
haploid
Which phase of mitosis is visible?
Which cells undergo meiosis?
sperm cells
Which characteristics allow you to identify cells in interphase?
DNA is not condensed and the nuclear envelope is present.
During the lab, chromatin stained this color.
red
Female gametes or sex cells are called
ovum
Females have XX chromosomes.
true
How many checkpoints are there in the cell cycle?
3
In meiosis I, what lines up at the metaphase plate and is then pulled apart?
homologous chromosomes
