PMAT
What happens in prophase?
Chromosomes condense and the nuclear membrane breaks down.
What happens to the cell during the G1 phase?
The cell grows and carries out normal functions.
What is cytokinesis?
The division of the cytoplasm into two cells.
What is a chromosome?
A structure made of DNA that carries genetic information.
What is the correct order of the cell cycle?
Interphase → Prophase → Metaphase → Anaphase → Telophase → Cytokinesis.
What happens during metaphase?
Chromosomes line up in the center of the cell.
What is the main purpose of the S phase?
DNA is copied (replicated).
How do animal cells divide during cytokinesis?
A cleavage furrow pinches the cell in two.
What is a sister chromatid?
One of two identical halves of a duplicated chromosome.
What stage comes after DNA replication?
G2 phase.
What is the job of spindle fibers?
They attach to chromosomes and help pull them apart.
What happens during the G2 phase?
The cell prepares for mitosis and makes proteins.
How do plant cells divide during cytokinesis?
A cell plate forms between the two new cells.
What is the cell cycle?
The series of stages a cell goes through to grow and divide.
What is the first stage of mitosis?
Prophase.
What happens in anaphase?
Sister chromatids separate and move to opposite sides.
Why is interphase important?
It allows the cell to grow and copy its DNA before division.
What is produced at the end of cytokinesis?
Two identical daughter cells.
What is mitosis?
The process of nuclear division that creates two identical nuclei.
What happens immediately after telophase?
Cytokinesis begins.
What happens in telophase?
Two new nuclei form and chromosomes begin to uncoil.
Is the DNA visible during interphase?
No, it is in loose chromatin form and not visible as chromosomes.
Does cytokinesis happen before or after mitosis?
After mitosis.
What is chromatin?
Loose DNA found in the nucleus before it condenses into chromosomes.
What is the final result of the cell cycle?
Two identical daughter cells.
