Proteins are polymeric chains that are built from monomers called amino acids. All structural and functional properties of proteins derive from the chemical properties of the polypeptide chain. There are four levels of protein structural organization: primary‚ secondary‚ tertiary‚ and quaternary. Primary structure is defined as the linear sequence of amino acids in a polypeptide chain. The secondary structure refers to certain regular geometric figures of the chain. Tertiary structure results from

no organized nucleus but instead they their DNA clumped in an area but there is no organized nucleus with a membrane. This is because prokaryotes don’t have mitosis or meiosis like other cells. Scientists don’t really have a good way of describing how they duplicate‚ but it’s not through normal means. It is sometimes called simple mitosis. On the other hand eukaryotes have a nucleus which contains the DNA and the information necessary to grow reproduce and function. The Information is stored in thin

It usually trumpets when it is frightened or in danger. It also groans to warn its group of danger saying "Danger ahead". It may howl to begin the hunt or to return to the den. To sum up‚ this animal makes loud noises for many reasons. Most importantly‚ the ……… hunts at (day – night) so it is a nocturnal

Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds‚ the primary structure (sequence of amino acids) remains the same after a denaturation process. Denaturation disrupts the normal alpha-helix and beta sheets in a protein and uncoils it into a random shape. Denaturation occurs because the bonding interactions responsible for the secondary structure (hydrogen

Hooverville has five shacks and a lean to. The shacks are made out of cardboard that I also spray painted to look like mud. The shacks are held together with hot glue. On the shacks I used some material to make roofs and door coverings. I made some trees and bushes on my Hooverville too‚ using Spanish moss. I got some sticks out of my front yard to make wood piles for the fires‚ to show that the people of Hooverville were hard workers. I even made a lean to over one of the wood piles for looks

Millions of people drink sports drinks like Gatorade everyday‚ But very few people actually know what ingredients make up their favorite sports drink. Gatorade was thought up in 1965 by an assistant coach of the Florida Gators at the University of Florida and his team of physicians who wanted to create something to help his players deal with the heat of the Florida sun. They created a concoction they deemed “Gatorade”‚ named after the team of course. The beverage set out to replenish not only the

The protein in consumed food turns into amino acid. The amino acid is used later replinish the proteins used.

There are many words to describe the 1930s‚ but equality was not one of them. From injustice lynching and kills of blacks to the stock market crash of 1929 that lead the United States into the Great Depression. The 30s plausible could be the worst years in US history. In “To Kill a Mockingbird” by Harper Lee‚ she uncovers all the hardships there were living during that time period. The story takes place in Maycomb a small town in Alabama and is narrated by the main character‚ a little girl named
