Grapes of Wrath society before ones self essays

Grapes of Wrath society before one's self essays The Grapes of Wrath is written by John Steinbeck as a political statement about the need to put the well being of society as a whole before the individual needs. He discusses this idea in the book through his three main central characters, Tom, Ma, Casy and through his intercalary chapters. Throughout the book they all come to realise this need and the events that lead up to their realisation are used as evidence to prove to the reader that this notion is indeed necessary. At the start of the book it is evident that Toms concerns are short sighted, naive and undeveloped. His concerns lay centrally with the family and he is yet to embrace the notion that unity among poor will lead to change. In one of the earlier chapters in the book, in a conversation with Ma about prison, Tom quotes, You cant go thinking when youre gonna be out. Youd go nuts, you got to think about that day, the nex day... This clearly illustrates the shortsightedness of Toms initial state of mind. He also says to Casy, I only climb fences when I got fences to climb. Casy however is aware throughout the book of the need to work as one and he is the one who inspires this train of thought in Tom. He tells Tom at the start of the book, Maybe all men got one big soul everbodys a part of. Casy starts also putting his faith into action when he covers for Tom for hitting the police officer. In jail he has an experience where one man starts yelling for more food, then another, then all of them do and they get more food. He then realises the greater good that can come from everybody working together. When he leaves jail he goes on a strike for the migrant farmers. Tom accidentally meets up with him again and Casy explains to Tom his story. At the time it doesnt seem like the message has quite gotten through to Tom but after Casys death and when Tom is seeking re...

10 Interesting Facts About DNA

10 Interesting Facts About DNA DNA or deoxyribonucleic acid codes for your genetic make-up. There are lots of facts about DNA, but here are 10 that are particularly interesting, important, or fun. Key Takeaways: DNA Facts DNA is the acronym for deoxyribonucleic acid.DNA and RNA are the two types of nucleic acids the code for genetic information.DNA is a double-helix molecule built from four nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). Even though it codes for all the information that makes up an organism, DNA is built using only four building blocks, the nucleotides adenine, guanine, thymine, and cytosine.Every human being shares 99% of their DNA with every other human.If you put all the DNA molecules in your body end to end, the DNA would reach from the Earth to the Sun and back over 600 times (100 trillion times six feet divided by 92 million miles).A parent and child share 99.5% of the same DNA.You have 98% of your DNA in common with a chimpanzee.If you could type 60 words per minute, eight hours a day, it would take approximately 50 years to type the human genome.DNA is a fragile molecule. About a thousand times a day, something happens to it to cause errors. This could include errors during transcription, damage from ultraviolet light, or any of a host of other activities. There are many repair mechanisms, but some damage isnt repaired. This means you carry mutations! Some of the mutations cause no harm, a fe w are helpful, while others can cause diseases, such as cancer. A new technology called CRISPR could allow us to edit genomes, which might lead us to the cure of such mutations as cancer,  Alzheimers  and, theoretically, any disease with a genetic component. Scientists at Cambridge University believe humans have DNA in common with the mud worm and that it is the closest invertebrate genetic relative to us. In other words, you have more in common, genetically speaking, with a mud worm than you do with a spider or octopus or cockroach.Humans and cabbage share about 40-50% common DNA.Friedrich Miescher discovered DNA in 1869, although scientists did not understand DNA was the genetic material in cells until 1943. Prior to that time, it was widely believed that proteins stored genetic information.
