Chromatin Isolation essays

Chromatin Isolation essays DNA is the blueprint for all living things. DNA is made of a material called chromatin. The purpose of this experiment was to attempt to isolate, or separate, chromatin from onion cells. My lab partner was Dave Sugg. Hypothesis: We should be able to isolate DNA from onion cells. Procedure: To begin, weigh out about 15 grams of onion cubes and place it in a 400 ml beaker. Add about 60 ml of homogenizing medium to the onion cubes. Place it in a warm water bath for 8 minutes. Dont let it tip over!!! This softens onion tissue and allows homogenizing medium to penetrate the onion. The enzymes also get denatured. Quickly cool the solution to 15-20 degrees Celsius in an ice bath. Dont let it tip over!! Put the cooled solution in a blender. Blend for 45 seconds at high speed. Pour the result into a 500 ml beaker. Put this into an ice bath for 8 minutes. Set up a filter (cheesecloth 2 layers) in a funnel during the 8 minute wait. Pour the white solution through the filter into the other 500 ml beaker (leave the foam behind!). Take 25 ml of filtrate and pour it into a clean 250 ml Erlenmeyer flask. Put the flask in an ice bath until it cools to 10 15 degrees Celsius. Slowly add 50 ml of ice cold ethanol down the side of the flask until a white, stringy chromatin pr ecipitate occurs (the stuff will look stringy and cloudy). Wind the stringy DNA on a glass rod by turning the rod in one direction only. Data: Before we poured the ice cold ethanol down the side of the flask in the final step, there was a film at the top of the solution. We poured in all 80 ml of ethanol. There were 3 clear layers; a clear ethanol layer at the top, a DNA interface, clear with whitish strands, and quite visible unlike the protein, and a yellow homogenate at the bottom. This experiment taught us the process of isolating DNA from onion cells. We learned a great deal from the completion of these extractions. We h ...

Values of Life Essay Example for Free

Values of Life Essay There are many values in life. To me a value is something that you enjoy, and appreciate around you. You also have a passion for the person, place or thing that you value. You have to be willing to fight for your values. There are many values in life but the two that are most important to me is wrestling and my Family. Wrestling has played a big tremendous role throughout my lifespan Family is the most important value because they will always be there for you no matter what. Wrestling is a significant value to me because it has played a crucial part in my life. It made me who I am today. Wrestling is different than most sports. It’s not just any sport you play its more like a lifestyle. You have to make sacrifices if you want to be successful at the sport. You have to give up allot of your everyday life routines. That consists of no parties, no junk food, no staying up late etc. When you give up things like this that is a value in itself. This value takes me places I never thought I could be going; from traveling all around the world to being here now at NDC. Some people would not consider a sport as an important value. Not for me I say if you are willing/have shed blood sweat and tears for that person place or thing, then that’s a value there. Family is the most appreciated value that I have. I love my family with all of my heart. I value them and they value me. There are so many values that come with family that you will always be able to share. You’re always with someone apart of your family from mom and dad to cousins. You will experience good and bad times with each and every one of them. They will teach you who you are not by choice, but because they are a part of you. They have characteristics the same as you. They are your blood. They help you with daily life problems, they taught you right from wrong, they have molded you the guide you, if all this is not a value I don’t know what it is. Your values will make you who you are. They make up the character in you. Without values I’m not sure where I would be right now, I would not be the same person that I am today. These two values Wrestling and Family have taught me hard work, determination, and business. For all of those I am very grateful, a glad that I had these though out my life My personal opinion if you don’t have values in life you really have nothing to live for, nothing to protect, nothing to drive you when times get hard, nothing to look forward to, not anything. People will judge you based off your important values. Wrestling is an important value to me because I’ve shed blood, sweat, and tears for the sport. My family is my number one value in my life because they’ve made be who I am today.

Bowers V Hardwick Supreme Court Case Essay -- Michael Hardwick

Bowers v. Hardwick United States Supreme Court Opinion This case, Bowers v. Hardwick, originated when Michael Hardwick was targeted by a policer officer for harassment in Georgia. A houseguest of Hardwick's let the officer into his home, where Hardwick was found engaging in oral sex with his partner, who was another male. Michael Hardwick was arrested and charged of sodomy. After charges were later dropped, Hardwick brought his case to the Supreme Court to have the sodomy law declared unconstitutional. Justice White delivered the opinion of the Court. Justice Burger, Powell, Rehnquist, and O'Conner joined, filing concurring opinions. In Justice White's opinion, or while delivering it, he mentioned a lot of steps that were taken by Michael Hardwick to have his case at the Supreme Court. Justice White also mentioned and compared past court cases that might had relevance or helped make his opinion more valid. The key issue that was focused on by Justice White was whether or not the Federal Constitution grants a fundamental right upon homosexuals to engage in sodomy. There were still laws in many states that made sodomy illegal, and have been in place for a very long time. When making his way to presenting his opinion of the Supreme Court, Justice White went through prior cases such as Loving v. Virginia, Roe v. Wade, Eisenstadt v. Baird, and many more; because the Court of Appeals and Hardwick claimed that these cases construed the Constitution to grant a right of privacy that stretch forth to homosexual sodomy. After reviewing prior cases and accepting the decisions in those cases, Justice White thought none of the rights announced in the previous cases bears any relevance or relation to Hardwick's claim that it is a cons... ...t it refused to notice the fundamental interest all people have in controlling the nature of their sexual relationships. Due to the activity that was conducted in Hardwick's home, the Fourth Amendment played an important role. The Fourth Amendment was not defined by the Court as being a violation for breaking a person's door, a going through their belongings. It was defined as an invasion of his indefensible right of personal security, personal liberty and personal property. Neither Georgia's law nor Georgia's prosecutor provided insufficient evidence and validity to support the conclusion that homosexual sodomy is considered unacceptable behavior in the state of Georgia. In result of this Court of Opinion, the Court ordered the dismissal of Hardwick's complaint because Michael Hardwick had alleged a constitutional claim well enough to withstand a motion to dismiss.
