Prokaryotes‚ Protists‚ and Fungi A. Characteristics -Genome- ca. 1000x smaller than eukaryotic genomes‚ contained within the nucleoid‚ plasmids. Page 559. -Single Circular Chromosome-within the nucleoid‚ does not have a physical structure‚ is just where you find DNA. -Plasmids-accessory DNA. The cause of antibiotic resistance. Some bacteria do not have plasmids. Plasmids are not always found in a living thing. Also 1000x less information than eukaryotic. Can be transferred by transcription. -Endospores

Anthropology 1: Human Evolution Recombinant DNA technology is defined as a series of procedures that are used to recombine DNA segments. A recombinant DNA molecule is constructed from segments of two or more different DNA molecules. Under certain circumstances‚ a recombinant DNA molecule can enter a cell and replicate‚ either on its own or after it has been integrated into a chromosome. Some examples of DNA technology are the insertion of bacterial DNA into certain crops‚ cloning‚ and genetically

Definition for antibiotic resistant bacteria: WebMD definitions: Antibiotic resistance is a type of drug resistance where a microorganism is able to survive exposure to an antibiotic. Genes can be... en.wikipedia.org/wiki/Antibiotic-resistant_bacteria Antibiotics were designed to kill bacterium that infect us. Unfortunately‚ they are indiscriminate and also kill the good bacterium that are mostly found in the large intestinal tract. This leaves a person open to reinfection‚ or other more

Compound Microscope Parts A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially‚ a compound microscope consists of structural and optical components. However‚ within these two basic systems‚ there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated

Penicillin Essay (25marks) Considered to be the first of the antibiotic medicines‚ and the first important commercial product to be produced by an aerobic‚ submerged fermentation‚ penicillin (as originally coined) strictly refers to the antimicrobial agent produced naturally by the microbe Penicilium notatum; a form of filamentous fungus. Originally discovered by Ernest Duschesne in 1896‚ it was later ‘rediscovered’ by Alexander Flemming in 1928‚ who was then credited for the discovery – though

Disjunction of Senses in Modern City life In his chapter “City Life and the Senses‚” John Urry discusses how the senses system operates in “open societies” of streams of crowds in open space. The five senses are comprised by the visual‚ auditory‚ touch‚ taste‚ and olfactory. Urry views visuality as an ambivalent force that is prioritized above the other sense through the developments of centuries and somewhat abused by as visual sense becomes increasingly accelerated in the city life dominated by

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane. The cell is the very smallest unit of living matter. All living things including plants and animals are made up of cells. Cells are made of atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant

Airway mucus is part of inborn immunity that facilitates the elimination of inhaled microorganisms. Antibacterial mechanisms such as lysozymes and defensins‚ which are contained in airway mucus‚ are key components of this inborn immunity (Gerson et al. 2000). While this defense mechanisms remains prevalent in cystic fibrosis patients it appears to be compromised in that it allows the growth of Pseudomonas aeruginosa in airway mucus. The fact that people with cystic fibrosis are equally exposed to
