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 hyperbole in the story "The Gift of the Magi" by O. Henry?

The most obvious use of hyperbole in "The Gift of the Magi" occurs when the narrator describes Della's and Jim's evaluations of their two treasures—her long, luxuriant hair and his gold watch. Had the Queen of Sheba lived in the flat across the airshaft, Della would have let her hair hang out the window some day to dry just to depreciate Her Majesty's jewels and gifts. Had King Solomon been the janitor, with all his...

What are some literary devices in Macbeth, Act V, Scene 1?

Act V, Scene i of Macbeth certainly continues the imagery that is prevalent in the play with its phantasmagoric realm, as in this scene a succession of things are seen or imagined by Lady Macbeth. Imagery - The representation of sensory experience Lady Macbeth imagines that she sees bloody spots (visual imagery) on the stairs; she also smells blood (olfactory imagery): Here's the smell of the blood still. All the perfumes of Arabia will not...

How can I analyze Moon and Six Pence by Somerset Maugham?

In "Moon and Sixpence," loosely based on the life of Paul Gaugin, Maugham presents a study of the tension between the "civilized" life of 19th century Europe, and the lead character's desire to throw off the shackles of bourgeois life. Charles Strickland is a middle-aged English stockbroker with a wife and family. By abandoning his domestic life, Strickland commits what many in European society would consider a gross betrayal of one of the foundations of...
