Premium DNA Gene Organism
Cell Organelles Nucleus Its function is to control the cell’s activities and retain the chromosomes. The nucleus is bound by a double membrane‚ the nuclear envelope. The nuclear envelope has pores in it to allow the transport of mRNA. The cytoplasm like material is called nucleoplasm which contains chromatin (coils of DNA and histone proteins)‚ it is chromatin that condenses to form chromosomes during cell division. Within the nucleus is a small spherical body called the nucleolus which

Stem cells are unique because they have the ability to generate new cells of any kind during early life and growth. There are about 200 different types of cells in the body; such as muscle‚ skin and brain cells. Most of these cells have to be repaired or replaced once in a while. For example our taste buds are replaced every 10 days‚ skin cells every couple of weeks and liver cells every 300-500 days. Stem cells serve as an internal repair system dividing essentially without limit to replenish

1] Describe the two branches of the ANS – transmitters‚ transmitter synthesis‚ outflow and major effects of each. The two branches of the Autonomic Nervous System are the sympathetic division and the parasympathetic division. The main process of the sympathetic division is to stimulate the fight-or-flight response in the body‚ which means it is in charge of stimulates actions. In the sympathetic system‚ epinephrine and norepinephrine are the main neurotransmitter. In the sympathetic system

- The major functions of the cell is concentrated at the outer edges of the retina and are used in peripheral vision. On average‚ there are about 125 million rod cells in the human retina. Rod cells are almost entirely responsible for night vision. Rod cells do not process fine details or color differences‚ but are highly sensitive to light. A single flash of light is all that is require to produce a response from a rod cell. Rod cells function as specialized neurons that convert visual stimuli in

Various types of Fuel Cells and their working By : Divykant Vishwakarma 03996404910 EEE 2nd shift S.No. 14 Fuel Cell A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel‚ but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air

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

Cells are some of the smallest organisms around. All living things consist of cells‚ and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly. All cells are separated from their surrounding by a cell membrane. The cell membrane regulates what enters and leaves the cell and also aids in the protection and support of the cell. A cell membrane

Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name‚ (also spelled "eucaryote‚") which comes from the Greek word referring to the nucleus. Animals‚ plants‚ fungi‚ and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the
