Which Phase?
The Cell Cycle
Random
100
The second phase of mitosis
What is, prophase
100
Long, thin fibers of DNA and proteins
What is, chromatin
100

§The cell is growing, carrying out normal cell functions, and preparing to replicate DNA.

What is, Interphase

100
What occurrence within the cell does the cell cycle represent?
What is, Cell Division
100
In Interphase chromosomes are copied?
What is, True.
200
During this phase, chromosomes line up in the center of the cell and spindle fibers attach to the centromeres.
What is, Metaphase
200
One half of a duplicated chromosome
What is, sister chromatid
200

These chromosomes are drawn by their spindle fibers to opposite ends of the cell

What is, Anaphase

200
What is the longest phase in the cell cycle?
What is, Interphase
200
In Prophase spindle fibers form between the poles?
What is, True.
300
These form during Prophase when chromatin condenses.
What is, chromosomes
300
Holds two sister chromatids together
What is, centromere
300

usually starts at about the same time as telophase

What is, Cykinesis

300
The cell cycle results in two genetically _________ cells.
What is, Identical
300
Mitosis is when cells divide
What is, True
400
These hold identical chromatids together.
What is, centromeres
400
Visible structure seen beginning in prophase
What is, chromosome
400

Formation of spindle fibers

What is, Prophase

400
Cell cytoplasm divides
What is, cytokinesis?
400
In Telophase chromosomes appear chromatin (Rods Rather than Threads)
What is, False It is like threads rather than rods.
500
In this phase, a new nuclear envelope appears.
What is, telophase
500

Compare centromere and centriole

Centromere: hold the chromatid togethe

Centroler:cylindrically shaped organelles

500

Nuclei are forming.

Telophase

500

3 detailed periods for interphase and its events?

G1:  cell growth, development, and protein production (longest)

S:  “Synthesis”, DNA replication

G2:  Organelles replicated (shortest)

500

Diffrence in animal and plant cells for Cytokinesis

In animal : cell membrane squeezes together around the middle of the cell

In plant: a cell plate forms across the middle of the cell and  new cell walls form around the membrane
