What is Cytokinesis?
Cell cytoplasm divides
100
What is chromatin?
Long, thin fibers of DNA and proteins
100
Important events in telophase?
the chromosomes begin to decondense
the spindle breaks down, and the nuclear membranes and nucleoli re-form.
The cytoplasm of the mother cell divides to form two daughter cells, each containing the same number and kind of chromosomes as the mother cell.
100
What is 46?
Chromosomes before mitosis = 46. Chromosomes at end of mitosis in each cell =
100
What is a cell plate?
a structure that forms when the cytoplasm of a plant cell divides.
200
What happened to the cell during S phase?
DNA replicates
200
What is a sister chromatid?
One half of a duplicated chromosome
200
What are the important events in Metaphase?
Chromosomes are lined up on the cell's equator
the nucleus dissolves and the cell's chromosomes condense and move together, aligning in the center of the dividing cell.
200
What is 2?
Cells produced
200
What is a cleavage furrow?
structure that forms during cell division, specifically during cytokinesis. it occur in animal cells and is responsible for dividing the parent cell into two daughter cells.
300
What is the G1 phase?
The cell grows and carries out normal activities after division has occurred
300
What is a centromere?
Holds two sister chromatids together
300
What is prophase?
The cell's chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides of the cell
300
What is once?
Times cell divides in each cell cycle
300
What is binary fission?
binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
400
What is interphase?
The stage that includes G1, S, and G2
400
What is a chromosome?
thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
400
What is anaphase?
Chromatids are pulled apart and become individual chromosomes
400
What is 2? ( during telophase)
Nuclei (if cell doesn't finish cytokinesis)
400
What are mitosis and cytokinesis?
Eukaryotes use these two steps to divide
500
What is the G2 phase?
Cell preparation for division occurs
The cell "double checks" the duplicated chromosomes for error, making any needed repair
500
What is DNA?
Nucleic acid that makes up the bulk of a chromosome
Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix.
500
What is the first stage of mitosis? Identify the important events in this stage.
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.

How many chromatids in a chromosome?
2

What is cancer?
Uncontrolled cell growth
