How is genetic information stored?

DNA is short for deoxyribonucleic acid. DNA is found in the nucleus of the cell. The nucleus is the control center, or the brain of the cell, so it would make sense that DNA is found here. DNA is a nucleic acid and it contains the genetic instructions for the function and development of living things. The role of DNA is to store genetic information. The genetic information is stored in the chemical structure of...

DNA is short for deoxyribonucleic acid. DNA is found in the nucleus of the cell. The nucleus is the control center, or the brain of the cell, so it would make sense that DNA is found here. DNA is a nucleic acid and it contains the genetic instructions for the function and development of living things. The role of DNA is to store genetic information. The genetic information is stored in the chemical structure of the DNA. There is a backbone that consists of a sugar and phosphate. Connecting the two backbones are the bases. The bases are adenine (A), thymine (T), guanine (G), and cytosine (C). The order that these bases are in is how the information is stored. The sequence of bases forms genes. Genes are what make you who you are and what allows all systems in your body to function. Each gene is a blueprint for a specific protein. For all of this information to fit inside of the cell it must be compacted. It gets wound up tightly and forms a chromosome. When a cell divides it must replicate the DNA inside of each cell so that the DNA can be passed onto the next cell and onto offspring.

What is the meaning of "juggling fiends" in Macbeth?

Macbeth is beginning to realize that the three witches have been deceiving him since he first encountered them. Like jugglers, they have kept changing their forecasts in order create confusion. This is particularly apparent when the Second Apparition they raise in Act IV,   Scene 1 tells him that no man of woman born can overcome him in hand-to-hand battle--and then Macbeth finds himself confronted by the one man he has been avoiding out of a... Macbeth is beginning to realize that the three witches have been deceiving him since he first encountered them. Like jugglers, they have kept changing their forecasts in order create confusion. This is particularly apparent when the Second Apparition they raise in Act IV,   Scene 1 tells him that no man of woman born can overcome him in hand-to-hand battle--and then Macbeth finds himself confronted by the one man he has been avoiding out of a sense of guilt, and that man tells him: Despair thy charm. And let the angel whom thou still hast serve...

What are some external and internal conflicts that Montag has in Fahrenheit 451?

 Montag, the protagonist of Fahrenheit 451, faces both external and internal conflicts throughout the novel. Some examples of these conflicts are: External Conflicts: Conflict with the society: Montag lives in a society that prohibits books and critical thinking. He faces opposition from the government and the people who enforce this law. Montag struggles to come to terms with the fact that his society is based on censorship and control. Conflict with his wife: Montag's wife, Mildred, is completely absorbed in the shallow and meaningless entertainment provided by the government. Montag's growing dissatisfaction with his marriage adds to his external conflict. Conflict with the fire captain: Montag's superior, Captain Beatty, is the personification of the oppressive regime that Montag is fighting against. Montag's struggle against Beatty represents his external conflict with the government. Internal Conflicts: Conflict with his own beliefs: Montag, at the beginning of th...

In A People's History of the United States, why does Howard Zinn feel that Wilson made a flimsy argument for entering World War I?

"War is the health of the state," the radical writer Randolph Bourne said, in the midst of the First World War. Indeed, as the nations of Europe went to war in 1914, the governments flourished, patriotism bloomed, class struggle was stilled, and young men died in frightful numbers on the battlefields-often for a hundred yards of land, a line of trenches. -- Chapter 14, Page 350, A People's History of the United States Howard Zinn outlines his arguments for why World War I was fought in the opening paragraph of Chapter 14 (referenced above). The nationalism that was created by the Great War benefited the elite political and financial leadership of the various countries involved. Socialism, which was gaining momentum in Europe, as was class struggle, took a backseat to mobilizing for war. Zinn believes that World War I was fought for the gain of the industrial capitalists of Europe in a competition for capital and resources. He states that humanity itself was punished by t...
