DNA DNA‚ or Deoxyribonucleic Acid‚ is described‚ in Encarta Encyclopedia as a genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by which DNA copies itself for each descendant cell or virus‚ passing on the information needed for protein synthesis. In most cellular

INTRODUCING WITH BIOCHEMICAL CYCLES Biochemical cycles Nutrients are important for organisms to function. Each nutrient has a role in global biogeochemical cycles. A nutrient is a chemical that organisms need to live and grow and are substances an organism’s uses for metabolism which must be taken in from its environment that enrich the organism. Two types of nutrients are macronutrients and micronutrients. Macronutrients are needed in large quantities while micronutrients are needed in smaller

Objectives 1. To determine biochemical activities of microorganisms. 2. To observe the product of biochemical activities of microorganisms. 3. To learn the skills of inoculation agar tubes and agar plates. Introduction Microorganisms are able to carry out different biochemical activities with the ease of different enzymes. Each of these enzymes carries out one specific type of the chemical transformation. They convert substrates into product. A) Carbohydrates Fermentation Microorganisms utilize

Biochemical Oxygen Demand (BOD) Biochemical Oxygen Demand‚ BOD‚ as it is commonly abbreviated‚ is one of the most important and useful parameters (measured characteristics) indicating the organic strength of a wastewater. BOD measurement permits an estimate of the waste strength in terms of the amount of dissolved oxygen required to break down the wastewater. The specifics of the analysis are discussed in detail in Standard Methods for the Examination of Water and Wastewater. The BOD test is

A Replication of the Stroop Effect Kimber-Ann Cook Broughton High School 3/26/08 Ms. Greene IB Psychology SL 1‚ 738 Abstract The Stroop (1935) effect is the inability to ignore a color word when the task is to report the ink color of that word (i.e.‚ to say "green" to the word RED in green ink). The present study investigated whether object-based processing contributes to the Stroop effect. According to this view‚ observers are unable to ignore irrelevant features of an attended object (Kahneman

Long stands of double helical DNA can fit into the nucleus of a single cell because DNA is specially packaged through a series of compaction events to fit easily within cell nuclei. Even though the length of DNA per cell is about 100‚000 times as long as the cell itself‚ it only takes up only about 10 percent of the cell’s volume. The DNA molecule‚ in order to condense‚ wraps itself around groups of histone proteins‚ and then the chromatin folds back on it‚ nucelosomes pack together to create a compact

The biochemical importance of water Sam Ellick 13/11/2010 Water otherwise known as H2O is a necessity for life to exist. It has many unique features compared to other molecules of its size. For example solid ice is less dense than liquid ice‚ which ponds and lakes freeze from the top down. This is important in insulating the aquatic life in the winter. This essay however will be looking at why water is so important in biochemical terms. Its shape Water‚ as its formula H2O suggests‚ consists

DNA: DNA is a double-stranded nucleic acid that contains the genetic information for cell growth‚ division‚ and function. DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus but a small amount of DNA can also be found in the mitochondria .The information in DNA is stored as a code made up of four nitrogen bases which are adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). these nitrogen bases are bind with

BIOCHEMICAL IMPORTANCE OF WATER Of all the simple chemicals that are found in abundance on Earth‚ only water is liquid under normal pressure and temperature. When life first appeared on planet Earth‚ water has played an important role in creating the first organic compounds. The organic compounds later‚ formed the first prokaryotic organisms. Life began‚ as the modern theories support‚ in water and developed for three billion years in it before spreading on land. It is no coincidence that the
