Cutting Up Morals essays

Cutting Up Morals essays Dissection should not be introduced in the lower education levels. It can damage personal morals of young developing minds, isnt good for the creatures involved, and is senseless since there are now several alternatives just as educational. It is also something that can affect every person differently and should not be part of a regular curriculum. Students who do wish to dissect as training for a future career should only be able to do so in higher education when they are old enough to really know what would be okay for them, not as immature students in high school or middle school. As children, everyone is brought up with some form of morals. They are taught to respect life and not to take it for granted. What happens when you take a middle or high school student, who happens to be but a child, with these morals fresh in their minds and shove a once breathing, life-filled creature surrounded with the cringing aroma of formaldehyde in front of their face? Then a razor is placed in their hand. This can leave any humane person confused. I remember being forced to dissect a pregnant rat in 9th grade. All the kids were playing around and cutting off the tails to learn of its value. I sat horrified as my science teacher grasped the frail bodies of three fetal mice, pulling the leg off of one. She simply stated oops like it was no big deal that four lives were just stripped helplessly from this earth. No one learned anything from this. Every single student failed the test and final exam over the anatomy of the rat. All they learned was that it was ok to cut up a mous es tail and disrespect death. This could be where the corruption of serial killers and such possibly evolve. Now, I am not saying that this is really how it always works, but whos to say it couldnt? Where do these animals come from anyway? The millions of frogs, rats, infant pigs, and cats could come from ...

How To Extract DNA

How To Extract DNA DNA or deoxyribonucleic acid is the molecule that codes genetic information in most living organisms. Some bacteria use RNA for their genetic code, but any other living organism will work as a DNA source for this project. DNA Extraction Materials While you can use any DNA source, some work especially well. Peas, such as dried split green peas,  are an excellent choice. Spinach leaves, strawberries, chicken liver, and bananas are other options. Dont use DNA from living people or pets, as a simple matter of ethics. 100 ml (1/2 cup) of a DNA source1 ml (â…› teaspoon) table salt, NaCl200 ml (1 cup) cold waterenzymes to denature protein (e.g., meat tenderizer, fresh pineapple juice,  or contact lens cleaning solution)30 ml (2 tablespoons) liquid dishwashing detergent70-90% rubbing alcohol or other isopropyl or ethyl alcoholblenderstrainercup or bowltest tubesstraws or wooden skewers Perform the DNA Extraction Blend together 100 ml of DNA source, 1 ml of salt, and 200 ml of cold water. This takes about 15 seconds on high setting. You are aiming for a homogeneous soupy mixture. The blender breaks apart the cells, releasing the DNA that is stored inside.Pour the liquid through a strainer into another container. Your goal is to remove the large solid particles. Keep the liquid; discard the solids.Add 30 ml liquid detergent to the liquid. Stir or swirl the liquid to mix it. Allow this solution to react for 5-10 minutes before proceeding to the next step.Add a small pinch of meat tenderizer or a squirt of pineapple juice or contact lens cleaner solution to each vial or tube. Swirl the contents gently to incorporate the enzyme. Harsh stirring will break the DNA and make it harder to see in the container.Tilt each tube and pour alcohol down the side of each glass or plastic to form a floating layer on top of the liquid. Alcohol is less dense than water, so it will float on the liquid, but you don t want to pour it into the tubes because then it will mix.  If you examine the interface between the alcohol and each sample, you should see a white stringy mass. This is the DNA! Use a wooden skewer or a straw to capture and collect the DNA from each tube. You can examine the DNA using a microscope or magnifying glass or place it in a small container of alcohol to save it. How It Works The first step is to choose a source that contains a lot of DNA. Although you can use DNA from anywhere, sources high in DNA will yield more product at the end. The human genome is diploid, meaning it contains two copies of each DNA molecule. Many plants contain multiple copies of their genetic material. For example, strawberries are octoploid and contain 8 copies of each chromosome. Blending the specimen breaks apart the cells so you can separate the DNA from other molecules. Salt and detergent act to strip away proteins normally bound to DNA. The detergent also separates the lipids (fats) from the sample. The enzymes are used to cut the DNA. Why would you want to cut it? The DNA is folded and wrapped around proteins, so it needs to be freed before it can be isolated. After you have completed these steps, the DNA is separated from other cell constituents, but you still need to get it out of solution. This is where the alcohol comes into play. The other molecules in the sample will dissolve in alcohol, but DNA does not. When you pour alcohol (the colder the better) onto the solution, the DNA molecule precipitates so that you can collect it. Learn More About DNA 10 Interesting DNA FactsDNA Versus RNADNA Facts Quiz
