the proteins that takes part in the catabolic activity within the cells and they act as a catalyst that is enhances and makes it faster the reaction of the hydrolysis of the molecules that would otherwise be slow and the normal physiological process can be slowed down and the life of the cells would not be possible anymore. The enzyme known as β - galactosidase is not only present in eukaryotic cells but also in prokaryotic cells. As the word indicates galatosidase, it means the breakdown of the

paperEarly in 1997, Scottish scientist Dr. Ian Wilmot revealed to the world that he had successfully cloned an adult sheep, Dolly. With this invention, the world made a collective gasp at the realization that cloning was no longer a pipe dream or an element of a Science Fiction movie. Since then, human cloning has become one of the most debated topics in the world. From the schoolhouse to the White House, discussions began regarding the ethical implications of human cloning. In several recent polls

Mario Gonzalez Professor Stamp English 1B 16 March 2014 Wall-e We as humans have the ability to live our own lives without the use of constant technology. Even so we have become dependent on it to live our daily lives. Less than a century ago we lived without being so dependent upon technology and we can again. Not to say that we should abandon technology completely but we have become entirely too dependent. In the Pixar movie “Wall-e”, humans have destroyed the planet due to their lack of care

employed in cheese making, and bacteria in yogurt making. Single- Cell Protein (SCP) Microorganisms are single cell organisms which can be cultured to rapidly produce foodstuffs rich in protein, minerals and vitamins. Microorganisms are grown in large fermenters where nutrient, pH and temperature are constantly monitored and controlled. The products are: 1. Cells 2. Substances produced by cells. 3. Substances the cells make by fermenting the nutrient solution. Once these products have

1. Introduction: Enzymes such as amylases, cellulases, xylanases and proteases are widely used in the industry for the manufacture of pharmaceuticals, foods, beverages and confectioneries as well as in textile and leather processing, and wastewater treatment. The potential applications of amylases, cellulases, xylanases and proteases in biotechnology have already been reviewed. The majority of the enzymes used in the industry are of microbial origin because microbial enzymes are relatively more stable

The stem cells have to constantly regenerate. They generate stem cells first. They have the mutation. They can go through manipulation and once they can go through the protein. Once they

to areas of lower concentration until the molecules are evenly distributed through the area. Osmosis is the dispersion of water. Our cells are capable of absorbing nutrients because, the cell membrane is selectively permeable (some molecules can diffuse freely through the membrane while others cannot). In this experiment we used dialysis bag as a model of the cell membrane. Our hypothesis was that the glucose will diffuse out of the membrane into the beaker filled with iodine solution. To demonstrate

Thomas Spann Biology Lab Plant Cell Definitions and Functions Nucleus: The cell nucleus is supposed to be the most important organelle. It carries the genetic information present in this organelle which inherits the physical traits from one generation to another. It has a dark stained nucleolus mainly responsible for protein formation. Apart from this, the nucleus coordinates all the cell functions and regulates the metabolism of plants. The passage of food and water and the influx of nutrients
