Name that
phase
G1, G2, & S
Mitosis
chromosomes structure
True or false
100

The second phase of mitosis

prophase

100
A certain species has 28 chromosomes in each of its newly formed daughter cells. The parent cells during G1 had this many chromosomes.
What is 28
100
This phase concludes nuclear division.
What is telophase
100

Long, thin fibers of DNA and proteins

.chromatin

100

In Interphase chromosomes are copied?

True.

200

During this phase, chromosomes line up in the center of the cell, and spindle fibers attach to the centromeres.

Metaphase

200
Chromatid pairs first form during S phase, however this phase marks the last time they are together.
What is metaphase
200
Longest stage of mitosis
What is metaphase
200

One half of a duplicated chromosome


sister chromatid

200

In Prophase spindle fibers form between the poles?

True

300

These form during Prophase when chromatin condenses.

chromosomes

300
Certain types of cells, like nerve cells, are said to be "stuck" in this phase.
What is G0
300
During prophase the nucleoli disappears, chromosomes condense, centrosomes move away from each other, and this begins to form.
What is mitotic spindle
300

Holds two sister chromatids together

centromere

300
Shortest stage of mitosis
What is anaphase
400

These hold identical chromatids together.


centromeres

400
Here the accuracy of DNA replication is evaluated and signals whether or not to begin mitosis.
What is the G2 Checkpoint
400
Lengthen during anaphase
What are nonkinetochore microtubules
400

Visible structure seen beginning in prophase

chromosome

400

equivalent and complete collection of two sister chromatin have reached the poles is when anaphase ends 

false 

equivalent and complete collections of chromosomes have reached the poles is when does anaphase end

500

In this phase, a new nuclear envelope appears.

telophase

500
This triggers the cell's passage past the G2 checkpoint into mitosis.
What is MPF
500
Monomer of microtubules
What is tubulin
500

Nucleic acid that makes up the bulk of a chromosome

DNA

500

nuclear envelope breaks and disappears. microtubules now reach the chromosomes, and some attach to the kinetochores. motor proteins move chromosomes towards the center is prometaphase
