What is Mitosis?
What happens in Mitosis?
DNA
Chromatid
Centromere

Define mitosis.
The usual method of cell division, characterized typically by the resolving of the chromatin of the nucleus into a threadlike form, which condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of two new cells resulting from the original cell.

What are the stages in Mitosis?
prophase metaphase anaphase telophase

True or False? DNA stands for Deoxyribonucleic acid
True

Define Chromatids.
One of two identical chromosomal strands into which a chromosome splits longitudinally preparatory to cell division.
100
Define Centromere.
A specialized structure on the chromosome, appearing during cell division as the constricted central region where the two chromatids are held together and form an X shape.

True or False: Cytokenesis is part of Mitosis.
False

True or False: Cells divide in this phase
True.

What does DNA look like?
A twisted ladder.
200
Where is chromatids located?
Inside the nucleus.
200
Where is centromere located?
Near the middle of the chromosome.

• The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell. • The first stage of meiosis, constituted by a series of events that include the thickening and coiling of the chromosomes, synapsis of homologous chromosomes, tetrad formation, and crossing over.
What is prophase?
300
The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.
What is telophase?
300
Does DNA play an active role in Mitosis?
Yes.
300
Are chromosomes and chromatid the same thing?
No, chromatids are single strands of chromosomes. Two chromatids are equivalent to one chromosome and are also referred to as sister chromatids.
300
What is the difference between chromosomes and centromeres?
A centromere is the center area on a chromosome when two sister chromatids have formed. if you remember in biology the picture of a chromatid it looked like an X. the centromere is where the X crosses.

How does plant cell mitosis differ from animal cell mitosis?
Plant cells lack centrioles.
400
The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle.
What is anaphase?
500
Where does mitosis happen in animals?
Mitosis happens everywhere in animals. Anywhere where new cells are being made mitosis happens. You can remember the difference between mitosis and meiosis by mitosis happens in your toes, meiosis just happens in ovaries and testes.
500
The stage of mitosis and meiosis, following prophase and preceding anaphase, during which the chromosomes are aligned along the metaphase plate.
What is metaphase?
500
Who discovered mitosis?
The first person to discover and study mitosis was Walther Flemming in 1870.

What will happen to a chromosome that lost its centromere?
It will be unable to pair with any other chromosomes and will result in programmed cell death (apoptosis).
