What is the process of DNA transmission?

DNA (deoxyribonucleic acid) holds all of our genetic information. Our genes are what allows our bodies to function and makes us who we are. DNA is found inside the nucleus of all of our cells. Eventually, all cells die and so they need to replicate themselves through the process of mitosis and meiosis. In this process DNA is replicated. DNA will first make a copy of itself in a process called replication with the aid...

DNA (deoxyribonucleic acid) holds all of our genetic information. Our genes are what allows our bodies to function and makes us who we are. DNA is found inside the nucleus of all of our cells. Eventually, all cells die and so they need to replicate themselves through the process of mitosis and meiosis. In this process DNA is replicated. DNA will first make a copy of itself in a process called replication with the aid of proteins. As a cell is dividing the chromosomes (tightly wound DNA) move to the center of the cell and then are pulled apart. So, half of a chromosome will be in each cell. Once the cell is separated the DNA is able to replicate itself so that a whole chromosome will be formed again. This process of cells dividing is called mitosis, which leaves you with two identical cells. Sex cells undergo meiosis, which is similar to mitosis except it undergoes division twice. The result is four cells that are not identical. Copied DNA is transmitted from one cell to the next but from parent to offspring through the egg and sperm.

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...
