Flashcards
Mitosis
What phase is this cell in?
metaphase
telophase
prophase
anaphase
Each chromosome consists of 2 .....
During which phase does the DNA make a copy of itself?
interphase
anaphase
metaphase
prophase
Cells will generally divide when?
they are 12 hours old
they have no food
they become too large
they are 8 hours old
Put mitosis phases into correct order.
anaphase
metaphase
telophase
prophase
Put mitosis phases into correct order.
1. prophase
2. metaphase
3. anaphase
4. telophase
What structure is responsible for moving the chromosomes during mitosis?
spindle
nuclear membrane
cytoplasm
nucleolus
The number of chromosomes in a gamete is the:
homolog number
diploid number
monoploid number
meiosis phase number
During cell division a chromosome is made of two distinct strands called
centromeres
homologs
chromatids
daughter cells
Cell size is an important factor in causing a cell to divide because a cells
shape changes often
surface area does not grow as fast as its volume
need for materials to be moved across its membrane is reduced
volume does not grow as fast as its surface area
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
4
16
2
DNA replication occurs during:
interphase
telophase
meatphase
prophase
During the cell cycle, the cell spends the most time in .... and the least amount of time in .....
Unlike plant cells, animal cells contain:
nucleoli
spindles
centrioles
cell walls
During which phase of mitosis do the chromosomes line up along the middle of the dividing cell?
metaphase
anaphase
telophase
prophase
When the DNA in a cell is uncoiled and spread throughout the nucleus it is called:
cromatin
chromosomes
chromatids
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:
aster
centropyge
cyclin
centrosome
Structure of proteins that forms at the centromere of each chromatid and helps attach the mitotic spindle to each sister chromatid is called:
Kinetochores
