Cell Cycle Definition- The process of the cell to divide into new cells. Interphase Description- the phase that occurs before cell division‚ the preparation for cell divisions Stages: G1- Rapid growth of the cell‚ metabolic activity. S- Synthesis‚ DNA replication. G2- Getting ready for cell division. Centrioles replicate Mitosis and Cell Division Function- To grow repair and maintain the cells in the body along with the reproduction of those cells. Results- Two identical daughter

Cell Fusion Introduction: The fusion of cells is a fundamental biological event that is essential for a variety of developmental and homeostatic processes. The importance of cell-cell fusion during development and disease is displayed in a variety of biological processes including‚ but not limited to‚ fertilization‚ development of tissues‚ the immune response‚ and aspects of tissue regeneration due to stem cells (Chen and Olson‚ 2005). Fertilization‚ which is the fusion of sperm and egg‚

him or her having Sickle Cell Disease. What this is is it’s a disease that is genetically inherited and it involves the red blood cells. Mutations in the HBB gene cause this disease. This disease is inherited in an autosomal recessive pattern‚ which means both copies of the gene in each cell will have mutations. The parents of offspring with an autosomal recessive gene each carry one copy of the mutated gene. The blood cells form an abnormal crescent shape (normal cells are in a disk form). The

Cell Specialisation All cells are designed to perform a particular job within an organism‚ that is‚ to sustain life. Cells can become specialized to perform a particular function within an organism‚ usually as part of a larger tissue consisting of many of the same cells working together for example muscle cells. The cells combine together for a common purpose. All organisms will contain specialised cells. There are hundreds of types of specialised cells. Below is listed some of the major ones

CHAPTER 12- THE CELL CYCLE I. Concept 12.1- Cell division results in genetically identical daughter cells A. Overview 1) The continuity of life is based on the reproduction of cells or cell division. 2) The cell division process is an integral part of the cell cycle‚ the life of a cell from the time it is first formed from a dividing parent cell until its own division into two cells. B. Cellular Organization of the Genetic Material 1) A cell’s endowment of DNA‚ its genetic

Animal Cells Vs. Plant Cells There are quite a few similarities and differences between plant and animal cells. Whether it be the internal parts of the cells‚ or the processes they go through. They also have differences in shape and sometimes size. These are only a few examples of similarities and differences between the two different cells. To begin with‚ both animal and plant cells are eukaryotic cells. This means that both cells have the same internal features‚ such as a cell membrane‚ a
