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

Brain of the Cell The nucleus is literally a membrane-bound organelle and is surrounded by a double membrane. I feel that the nucleus is of the greatest importance in the cell because it is the control center that oversees the metabolic functioning of the cell and it directs all the cells activities. The nucleus is like the head of the cell and without a head the rest of the body is useless. It is the largest organelle and within the nucleus is the DNA responsible for providing the cell with its unique

just a chain of ami. tacids makes up the primary structure. The secondary structure is formed by hydrogen bonds joining the chains in certain places to make an alpha helix or a beta sheet. The tertiary structure is formed by even more folding and joining of the chains to make a globular mass or fibrous mass. An example of this would be a carrier protein. Proteins are needed for many things they are needed in our diet for growth and repair of cells‚ enzymes and hormones in the body are used for the

The Human Egg Cell. The human egg cell is also known as the ovum. With a spherical structure it is the largest cell in the human body measuring about 0.2mm in diameter. The function of the ovum is to reproduce‚ when fertilized by the sperm cell the ovum is capable of creating a new living organism. The size and shape of the ovum gives it space to store and create nutrients (see fig 3) (Boyle and Senior 2008) The ovum is bounded by the egg follicles of the ovaries and is produced by primitive germ

Sociology 101 July 24‚ 2013 Structural Functionalism The structural theory sees the family as a social group that preforms certain essential functions for society. If these functions are not carried out then the family is odd or known to be dysfunctional. The family is like our body that has different parts and each part has a different function. The family is the backbone of the society and if it fails to pass on certain values and attitudes to its members then society will be affected. in
