Studied by 3 peoplethe DNA is copied, a new cell membrane forms between the DNA copies, and the cell splits into two cells
in a bacterium, cell division takes place when..
G1→S→G2→M→C→
What is the correct sequence of the cell cycle?
has a complete set of 46 chromosomes
after m and c the 2 new cells have how many chromosomes?
receives an exact copy of all the chromosomes present in the original cell
As a result of mitosis, each of the two new cells produced from the original cell during cytokinesis
a cell’s nucleus divides
Mitosis is a process by which
yes
does cytokinesis differ in plant cells and animal cells?
goes up
what does a cancer cell graph look like?
the ratio of volume to surface area increases
what happens as a cell grows larger and larger?
12
If a cell has 12 chromosomes how many will each daughter cell have?
it isn’t specialized in structure and function
a stem cell has potential medical uses because it
chromosome
form of DNA needed for mitosis to occur
chromatid
name for the identical half of a replicated chromosome
mitosis
what stage involves the division of the nucleus
interphase
the cell grows, functions and copies its DNA during this stage
centromere
holds 2 sister chromatids together
cytokinesis
this stage involves the division of the cytoplasm
chromosome
tightly coiled form of DNA
chromatin
relaxed, uncoiled DNA
chromatin
form of DNA during interphase
daughter cells
new cells formed through mitosis
binary fission
reproduction of prokaryotic cells
G-0
when a cell exits the cell cycle to continue functioning by stops dividing
prophase
centrioles begin to form spindle fibers and move to opposite poles of the cell
interphase
DNA is in the form of chromatin
anaphase
spindle fibers shorten, pulling apart 2 sister chromatids into unreplicated chromosomes
S phase
DNA is copied
telophase
nuclear envelope reforms
prophase
chromatin coils into replicated chromosomes
centromere
protein disc that holds 2 sister chromatids together
metaphase
spindle fibers arrange replicated chromosomes along the middle of the cell
telophase
chromosomes uncoil and relax back into chromatin
cytokinesis
cell membrane starts to pinch in, forming a cleavage furrow
animal- cleavage furrow (cells pinch in before splitting)
plant- cell plate forms that splits it into 2 cells
cytokinesis difference in animal and plant
create more cells in our body + heal ourselves
why does mitosis occur?
small cells are better at communication and exchanging materials
large cells are bad bc their volume is bigger than their surface area and it means the cells cant function properly
why do we need small cells instead of a few large cells?
