MITOSIS
The longest phase of mitosis
What is Prophase?
The type of cells cell division produces in meiosis
What are Gametes (sperm and egg cells)?
Both mitosis and meiosis begin with this type of cell, which contains two sets of chromosomes.
What is a Diploid cell?
During this stage, the chromosomes, which were distinct and condensed, begin to spread out into a tangle of chromatin.
What is Telephase?
The three main parts of the cell cycle
Interphase (G1, S, G2) plus Mitosis and Cytokinesis
The phase when the centromeres of the duplicated chromosomes line up with one another at the center of the cell.
What is Metaphase?
How one finds the haploid number based on a diploid number
Divide the diploid number by 2
In both mitosis and meiosis, this process involves chromosomes condensing, spindle fibers forming, and chromosomes moving toward opposite poles of the cell.
What is Prophase?
This term is used to describe pairs of chromosomes having DNA segments or genes for the same trait.
What is Homologous?
This may cause a cell to bypass a growth checkpoint, therefore causing a cancerous tumor.
What is DNA Mutation?
This type of animal cell undergoes mitosis
What are All Body Cells?
These human cells contain 23 chromosomes, half the normal amount
What are Haploid?
This process involves crossing over of homologous chromosomes, which occurs during prophase I.
What is Meiosis?
When in animal cells, the cell membrane is drawn inward and in plant cells, a cell plate forms
What is Cytokinesis?
A disorder in which body cells lose the ability to control their growth
What is Cancer?
The stage of mitosis where the sister chromatids are separated and pulled to opposite ends of the cell.
What is Anaphase?
The stage in which homologous chromosomes separate
What is Anaphase I?
In this type of cell division, the daughter cells have the same number of chromosomes as the parent cell, making them diploid.
What is Mitosis?
The stage when DNA replication occurs
What is Synthesis?
If cells do not do this, they do not move on to the next phase of the cell cycle.
What is Pass a checkpoint?
Where sister chromatids are joined when a chromosome is duplicated
What is the Centromere
The reason meiosis increases genetic variation
Meiosis provides for chromosomal variation in the gametes
Name one major difference between mitosis and meiosis
Mitosis = one division, identical cells
Meiosis = two divisions, varied cells
This loosely packed form of DNA is found in the nucleus during interphase and condenses to form chromosomes during cell division.
What is chromatin?
These three things happen during interphase.
What are cell metabolism, cell growth, and DNA replication?
