What is the cell cycle?
The cycle of growth, development, and division.
What happens during the mitotic phase?
A cell reproduces
What does a cell copy before it divides?
Organelles
What is the first stage of interphase?
G1, Rapid growth
What happens during the G2, the final stage of interphase?
It's a period of growth and the final preparation for mitosis.
What do organisms do during the cell cycle?
Grow and develop cells, replace old or damaged cells, and produce new cells.
Which phase makes up most of the cell cycle?
Interphase
What is DNA called during interphase?
Chromatin
During which phase is the duplicated DNA condensed into chromosomes?
Prophase
What happens during the S stage of interphase?
The cell replicates its strands of chromatin.
What are the 2 main phases of the cell cycle?
Interphase
Mitotic Phase
In _________, the cytoplasm and its contents divide.
Cytokinesis
Why is the cell cycle important for reproduction in some organisms?
Growth in multicellular organisms, replacement of worn out or damaged cells, repair of damaged tissue
What are sister chromatids held together by?
The centromere
What does the cell cycle result in 2 of?
Daughter cells
What happens during interphase?
Cells grow and develop
After mitosis, what is is that usually divides a cell's cytoplasm, forming a new cell membrane around each daughter cell?
cytokinesis
What are the two identical strands of DNA that make up the duplicated chromosome?
Sister chromatids
What are genetically identical to each other and to the original cell, which no longer exists?
Two daughter cells
Which stage do the nucleus and its contents divide?
Mitosis
What are the 3 stages of interphase?
Rapid growth and replication of organelles
Replication of DNA
Preparation for cell division
What results from mitosis and cytokinesis?
Two new daughter cells
What happens during anaphase?
Sister chromatids in each duplicated chromosome separate and are pulled in opposite directions by the spindle fibers.
What occurs during metaphase?
The chromosomes line up in the middle of the cell.
What happens during telophase?
Chromosomes begin to uncoil and two new identical nuclei form.
