100

In this stage, the cell grows.

What is G1

100

In cytokinesis, the cell completely divides into two of these.

What are daughter cells?

200

When a cell duplicates DNA

What is interphase?

200

During telophase of an animal cell, this forms

What is a cleavage furrow?

200

The number of sister chromatids in anaphase.

What is 8?

200

In this stage, DNA replication occurs

What is S phase?

200

In prometaphase this fragments.

What is the nuclear envelope?

300
When the nuclear envelope fragments

What is prometaphase?

300

During prophase, these begin to form

What are spindle fibers?

300

Another name for the kinetochore.

What is a centromere?

300

Interphase has checkpoints, at this checkpoint apoptosis may occur if the cell cannot pass.

400

When chromosomes condense

What is prophase?

400

Chromosomes line up here

400

During telophase chromosomes do this.

400
At this checkpoint, DNA replication is checked

400

In anaphase this elongates.

What is the cell?

500

When a vesicle travels to the middle of the cell and produces a cell plate

What is Cytokinesis?

500

In the second stage of mitosis, microtubules begin to attach to these.

What are kinetochores?

500

The end of chromosomes is called this.

What are telomeres?

500

When a cell cannot pass the G1 checkpoint it goes here.
