created in 2001. Out of the 30 babies that were born‚ 15 were found to have DNA from three different adults. Although having DNA from more than two sources can occur naturally‚ these 15 babies were created with a method called “cytoplasmic transfer‚” which had been banned by the FDA . The method was initially developed to save female eggs that had been difficult to fertilize and was showing much promise—until tracking the growth of the genetically modified babies revealed that one of the babies had

On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase is an enzyme found in food such

Genetically Engineered Foods or Organisms Genetically Engineered Foods or Organisms Biological Basis Genetically modified crops (GMCs) are plants having DNA altered through genetic engineering techniques. The goal is to introduce a new desirable trait to a plant that does ordinarily occur in the species. Desirable characteristics include resistance to environmental conditions‚ resistance to diseases and specific pests and production of a particular nutrient. Genetic

A Quantitative Enzyme Study: CATALASE FlowChart Purpose: Measure the rate of enzyme activity in different conditions Procedure: A. Extraction of Catalase 1. Peel potato 2. Cut into cubes 3. Mass 50g 4. Measure out 50ml of cold distilled water in blender 5. Add crushed ice into blender (small amount) 6. Add the potato cubes into the blender 7. Turn on blender on high for 30 seconds 8. Prepare an ice bath - FROM THIS POINT ON PREPERATION MUST BE CARRIED OUT IN AN ICE BATH – 9

Genetically Modified Organisms are Harmful For the past 25 years the United States has been putting their people in harm’s way. They have been doing this by allowing government agencies to grow and sell genetically modified foods and organisms to the public without informing them of what they’re consuming (2011 responsibletechnology.org). Most people do not know that a large quantity of the foods they are eating are not natural and are actually mutations of real healthy foods that take tons of chemicals

conditioning assumes that organisms are essentially passive – they just hang around waiting for stimuli to respond to. To Skinner it seemed obvious that people and animals actively engage with their environments. Skinner’s important insight was that an animal’s – or a person’s – behaviour was determined by the consequences of its past behaviour. Skinner’s Main Ideas Main Idea Operant conditioning Reinforcement Punishment Shaping Stimulus control What’s This? A type of learning in which future behaviour

The effect of mutations on living organisms Mutations occur when there is a change in the base sequence on the DNA strand. Most mutations have absolutely no effect due to them occurring in the introns‚ or the “junk DNA”. However some mutations occur on the exons‚ and these are the ones that can be potentially harmful to the organism‚ although in some exceptional cases random mutations can be beneficial‚ and pressured mutations are almost always beneficial to the survival of a species. Harmful

Model organisms are organisms used for research. They are alive‚ non-human species used for the purpose of studying different human diseases or other related experiments in which human testing would be considered either unsafe or unethical. Scientists study a particular biological phenomenon on a model organism and try to relate their findings to other types of organisms that are more difficult to study. As an example‚ 60% of human disease genes have an equivalent in the fruit fly and nematode worm

A planarian is free-living flatworm that lives in fresh water. Planarians are organisms that live in freshwater. Planarians are part of the metazoan phylum. Animals in the metazoan like jellyfish have the ability to regenerate (Raymond 511-512). Planarians are closely related to animals like jellyfish and starfish. These animals shared the same special ability to regenerate; starfish are able to regenerate their arm when it is cut off. Jellyfish are able to regenerate their stinger when cut off (Li

Organism Physiology The course in which different kinds of living organisms are thought to have developed from earlier forms during the history of the earth is defined as Evolution. Many time organisms evolve due to environmental changes. To better understand evolution this paper will review a diagram of an organism and explain how the organism has evolved physiologically to become suited to fit its environment. Organism To understand the evolution of an organism it is important to understand
