The basic structure of all the penicillins consists of a thiazolidine ring fused with a beta-lactam ring‚ creating a fundamental nucleus (also known as 6-amino penicillanic acid) crucial for their antibacterial activity. A wide variety of semisynthetic penicillins are produced by altering the composition of the side chains attached to this nucleus.The molecular formula of penicillin is C16H18N2O4S and weight of 334.39 g/mol‚ each base with a variable side chain‚ “R” that differentiates the penicillins

I. Describe the structure and function of the nucleus and mitochondria. The mitochondria is a semi-autonomous organelle which reproduces by bynary fission and has its own DNA. Its main function is to produce the energy intermediate ATP‚ through ATP synthase. Mitochondria could be considered a cell inside a cell. It has its own membranes (inner and outer membranes)‚ its ribosomes (to produce the proteins encoded in its DNA)‚ a matrix -- where aerobic respiration occurs. The invaginations of the inner

base of power that can be hard to control. Max Weber believed that bureaucracies share certain characteristics: chain of command‚ division of labor‚ and impersonality. The chain of command is a type of association characterized by a hierarchical structure of authority. In a military context‚ for instance‚ the chain of command is the line of power and obligation along which orders are passed within a military unit and between different units. The division of labor is when work is partitioned among

The race to find the structure of DNA was on. James Watson and Francis Crick model builders were working on finding out the structure of DNA first. I Rosalind Franklin a crystallographer am also working on finding the structure of DNA. But before I could officially identify the structure of DNA‚ Watson and Crick were successful. Now James Watson is writing a book about DNA‚ and I am told to give some feedback about it. I will be telling you about what I think about James Watson’s book‚ The Double

DNA DNA‚ or Deoxyribonucleic Acid‚ is described‚ in Encarta Encyclopedia as a genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by which DNA copies itself for each descendant cell or virus‚ passing on the information needed for protein synthesis. In most cellular

Long stands of double helical DNA can fit into the nucleus of a single cell because DNA is specially packaged through a series of compaction events to fit easily within cell nuclei. Even though the length of DNA per cell is about 100‚000 times as long as the cell itself‚ it only takes up only about 10 percent of the cell’s volume. The DNA molecule‚ in order to condense‚ wraps itself around groups of histone proteins‚ and then the chromatin folds back on it‚ nucelosomes pack together to create a compact

Write a 350 to 700 word summary describing if the collection of DNA without consent unreasonably intrudes on an arrestees’ expectation of privacy. How long can police keep your DNA on file after an arrest or conviction? Can law enforcement use a person’s DNA to match against other crimes unrelated to the one they initially obtained it for? Provide examples and or reasons. The collection of DNA without consent can unreasonably be seen as intruding on someone who has been not been arrested however
