Cell Cycle 1
What are the two main phases of the cell cycle?
Interphase
Mitotic (mitosis)
During which phase of the cell cycle is chromatin duplicated?
Interphase
S phase
During which main phase of the cell cycle do mitosis and cytokinesis occur?
Mitotic
What are the two stages of the mitotic phase?
mitosis
cytokinesis
What happens to the original cell when it divides into daughter cells?
It no longer exists.
Which phase of the cell cycle is the period of growth and development?
Interphase
During which phase do the nucleus and cytoplasm divide?
Mitotic
How many stages are there in the Interphase phase of the cell cycle?
How many stages are in the mitotic phase of the cell cycle?
2
What are the 3 stages of Interphase?
G1, S, G2
What are the 2 stages of of the Mitotic Phase?
Cytokinesis, Mitosis
What happens during the G1 stage in the Interphase?
Rapid growth and replication of organelles
What happens in the S stage of Interphase?
DNA replication
What happens in the G2 phase of Interphase?
Preparation for cell division
What happens during cytokinesis?
Cytoplasm and its contents divide and form 2 identical cells.
What is the difference between mitosis and cytokinesis?
In cytokinesis, the cytoplasm and its contents divide.
What makes up a chromosome?
2 sister chromatids attached at the center by a centromere.
How is the cell cycle important to some unicellular organisms?
It allows some unicellular organisms to reproudce by producing 2 identical organisms from 1 parent organism.
How is the cell cycle important to multicellular organisms?
It allows them to produce more cells for growth, to replace cells, and to repair damage.
How are interphase and the mitotic phase related?
Interphase prepares the cell to reproduce in the mitotic phase.
What happens during the 3 stages of interphase?
Rapid growth and replication of organelles, replication of DNA, and preparation for cell division.
What is produced at the end of the cell cycle?
2 identical daughter cells that are identical to the parent cell
How does a cell at the end of the first phase of the cell cycle differ from a cell at the end of the second phase?
At the end of the first phase, a cell has grown, organelles have been replicated, chromosomes have been replicated. At the end of the 2nd, chromosomes and cytoplasm have been divided. Cell has become 2 identical cells.
What are the 4 parts in the mitotic phase of the cell cycle?
metaphase, anaphase, telophase, prophase
What are the two main phases of the cell cycle?
Interphase, Mitotic
