Flashcards
Mitosis
What phase is this cell in?
prophase
metaphase
anaphase
telophase
Each chromosome consists of 2 .....
During which phase does the DNA make a copy of itself?
prophase
interphase
metaphase
anaphase
Cells will generally divide when?
they are 8 hours old
they become too large
they have no food
they are 12 hours old
Put mitosis phases into correct order.

What structure is responsible for moving the chromosomes during mitosis?
cytoplasm
nuclear membrane
nucleolus
spindle
The number of chromosomes in a gamete is the:
diploid number
meiosis phase number
homolog number
monoploid number
During cell division a chromosome is made of two distinct strands called
daughter cells
homologs
chromatids
centromeres
Cell size is an important factor in causing a cell to divide because a cells
need for materials to be moved across its membrane is reduced
volume does not grow as fast as its surface area
shape changes often
surface area does not grow as fast as its volume
surface area does not grow as fast as its volume
If a cell that has 8 chromosomes goes through mitosis, how many chromosomes will each new cell have?
8
16
4
2
DNA replication occurs during:
meatphase
prophase
interphase
telophase
During the cell cycle, the cell spends the most time in .... and the least amount of time in .....
Unlike plant cells, animal cells contain:
cell walls
nucleoli
spindles
centrioles
During which phase of mitosis do the chromosomes line up along the middle of the dividing cell?
metaphase
anaphase
prophase
telophase
When the DNA in a cell is uncoiled and spread throughout the nucleus it is called:
chromatids
chromosomes
cromatin
Structure present in the cytoplasm of an animal cell that is the organizing center of the mictrotubules in which the assembly of the spindle microtubules begins is:
centropyge
centrosome
aster
cyclin
Structure of proteins that forms at the centromere of each chromatid and helps attach the mitotic spindle to each sister chromatid is called:
Kinetochores
