List two of the three things that are
happening in the cell during
interphase
Growing, preparing for division,
copying DNA
DNA takes this form during
interphase.
chromatin
A resting phase; cells that are not
dividing but are functioning as
normal remain in the...
Go Phase
The S phase is characterized by…
DNA replication
To ensure everything happens in the
cell cycle correctly, there are
multiple..
checkpoints
At the beginning of mitosis, the cell
is called the __________ cell.
Parent
In anaphase of mitosis, the
__________ separate.
Sister chromatids (chromosomes)
The phase of mitosis that is
characterized by the arrangement of
all chromosomes along the center of
the cell is called…
metaphase
The products of mitosis are ______
cells that are ________.
2 (identical)diploid cells
Give an example of a cell that
undergoes mitosis.
Somatic (body) cells
When two pairs of homologous
chromosomes line up in Prophase I
of meiosis, it is called a _________.
tetrad
Homologous chromosomes move to
the middle and line up next to each
other…
Metaphase I
The products of meiosis are
________ cells that are _______.
4 (different) haploid cells
The phases of meiosis are the same
as mitosis except that…
Meiosis produces 4 haploid cells
instead of 2 diploid cells. The
daughter cells of meiosis are not
identical to mother cell.
Crossing over occurs…
During prophase I
Tightly coiled DNA and histone
protein is referred to as a …
chromosomes
A pair of similarly shaped
chromosomes are called_____
Homologous chromosomes
The point at which two chromatids
are attached to each other in a
chromosome is called a…
centromere
Homologous chromosomes are pairs
of chromosomes containing genes
that code for ______ traits
The same
In humans, the X and Y
chromosome are called the:
Sex chromosomes
After telophase, __________
happens and the cytoplasm divides
in half.
cytokinesis
During prophase, the nucleus…
Breaks down
The process by which prokaryotes
(bacteria) reproduce…
Binary fission
Normal cells become cancer when…
Cells are not responding normally to
control mechanism, regulation is
lost, and the cell continuously
divides.
How many chromosomes are in the
body cell of an organism that has a
haploid number of 15?
