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.

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.

How and why does James Gatz become Jay Gatsby? Describe the young Gatsby/Gatz.

James Gatz, a poor Midwestern boy of probable Jewish lineage, becomes Jay Gatsby, a presumed WASP and wealthy socialite, when he moves to New York City and acquires his fortune. It is wealth that has allowed Gatz to transform himself into Gatsby. However, those who know his background (e.g., Daisy and Tom Buchanan) never allow him to forget that he is nouveau riche -- that is, an upstart who has just recently made his fortune,...

What gift did Della buy for Jim and why in "The Gift of the Magi" by O. Henry?

Della buys Jim a watch fob because his watch is his most prized possession. Della and Jim Young do not have much money. Despite this, Della really wants to buy Jim a good Christmas present. She is even willing to sell her hair to get him a nice gift. This is ironic because we learn Della and Jim both highly prize her hair. Now, there were two possessions of the James Dillingham Youngs in which... Della buys Jim a watch fob because his watch is his most prized possession. Della and Jim Young do not have much money. Despite this, Della really wants to buy Jim a good Christmas present. She is even willing to sell her hair to get him a nice gift. This is ironic because we learn Della and Jim both highly prize her hair. Now, there were two possessions of the James Dillingham Youngs in which they both took a mighty pride. One was Jim's gold watch that had been his father's and his grandfather's. The other was Della's hair.  Della is still willing to sell her hair so she can b...

Explain and discuss how the definitions of freedom change for the nation, for the freedmen and for southern whites after the Civil War.

After the Civil War, the definition of freedom changed in the nation, as slavery was ended with the 13th Amendment to the Constitution in 1865. The practice of slavery was disallowed, but definition of the freedom that would take its place was a subject of controversy, ongoing debate, and even violence in the decades to come.  For freedmen, freedom often meant reconciling with their families, who were broken up by slavery; choosing which church to...
