Cell Cycle
100
surface area to volume ratio
What is the most important limitation in cells?
100
prophase, metaphase, anaphase, and telophase
What are the four stages of mitosis?
100
a kind of cell division that reduces the number of chromosomes by half through the separation of homologous chromosomes
What is meiosis?
100
mitosis out of control
What is cancer?
100
interphase, mitosis, and cytokinesis
What are the three main stages of the cell cycle?
200
smallest organizational unit of life
What are cells?
200
A stage in mitosis that includes: chromosomes that reach poles of cell nuclear envelope re-forms nucleolus reappears chromosomes decondense
What is telophase?
200
eight stages
How many stages are in meiosis?
200
crowd normal cells causing tissue and organs to stop working
How can cancer cells kill an organism?
200
the cell cycle
What is a cell's cycle of growing and dividing called?
300
cells contain DNA in their nucleus
Do cells contain DNA and if so where?
300
microtubles shorten, moving chromosomes to opposite poles
What happens during anaphase?
300
when a section of one chromosome changes places with a section of its homologous chromosome
When does "crossing over" occur?
300
mutations, or changes, in segments of DNA that code for production of proteins, including those that regulate the cell cycle
What is one cause of cancer?
300
at the end of the cell cycle
What is when is cell division complete and the original cell has become two daughter cells?
400
body cells and reproductive cells
What type of cells are produced in mitosis and meiosis?
400
metaphase
What stage has chromosomes that attach to the mitotic spindle and align along the equator of a cell?
400
reproductive organs of plants and animals
Where does meiosis is take place?
400
failure of a cells repair system
How can cancer result?
400
a cell will either stop growing or divide
What happens when a cell reaches its size limit?
500
found on chromosomes
Where are the instructions for each trait found?
500
nuclear membrane disintegrates, nucleolus disappears, chromosomes condense, and mitotic spindle begins to form between the poles
What is a description of prophase?
500
production of gametes for sexual reproduction
What is the purpose of meiosis?
500
the cytoplasm of the cell divides, forming two daughter cells
What is cytokinesis?
