| Why are cells limited in size? | ||
| The production of genetically identical offspirng from a single parent | ||
| The production of offspring that has genetic information inherited from two parents | ||
| Genetic information is bundled into packages of DNA called | ||
| Thin strands of DNA and proteins within the nucleus is called | ||
| Prokaryotic cells like bacteria undergo a type of asexual reproduction called... | ||
| Interphase is broken down into three phases called... | ||
| The normal growth phase of the cell is called... | ||
| The phase in interphase when DNA is replicated is called... | ||
| The phase in interphase when the cell begins to form centrioles and other parts to prepare for cell division (mitosis) | ||
| The M phase consists of two main stages which often overlap. They are... | ||
| phase of mitosis when the nuclear envelope disappears, chromatin forms chromosomes and centrioles and spindle fibers move to opposite sides: |  | |
| The sides of a chromosome are connected together by a ... | ||
| Each side of a chromosome is called a... | ||
| phase of mitosis when the spindle fibers cause the chromosomes to line up in the middle of the cell in a single file line. |  | |
| phase of mitosis when chromosomes separate and move along spindle fibers to opposite ends of the cell |  | |
| phase of mitosis when chromosomes untangle, nuclear envelope begins to be made again, centrioles and spindle fibers dissinigrate and the cell begins to pinch inward forming two new cells |  | |
| The cell spends most of its life in... |  | |
| a family of proteins that regulate the cell cycle | ||
| a group of proteins that respond to event occuring inside the cell. (like spindle fibers attaching to centromeres) | ||
| a group of proteins that respond to events outside the cell. (like damage to the skin) | ||
| external regulators that stimulate the growth and division of cells. Very important in embryo development and wound healing | ||
| Typically cells will slow down dividing when they come in _________ with each other. | ||
| programmed cell death | ||
| cell and chromatin shrink, cell membrane breaks off, neighboring cells clean up the cell's remains | ||
| uncontrolled cell growth | ||
| a mass of cells | ||
| mass of cells that does not spread to surrounding healthy tissue or to other pats of the body | ||
| mass of cells that invade and destory surrounding healthy tissue | ||
| process of malignant cells leaving the tumor and traveling to healthy tissue via the blood stream or lymph system to begin secondary tumors. | ||
| General reason for what causes cancer | ||
| Sources of cancer | ||
| Enviromental factors that increase the risk of cancer | ||
| Three treatments for cancer | ||
| Chemical compounds that kill or slow down cancer cells but also interfere with cell division in normal, healthy cells. |
