Cell Biology 1 – Prokaryotes & Viruses * Eukaryotes have a membrane whereas a prokaryote has no nuclear membranes. Both have a double stranded DNA. * The two main types of prokaryotes are bacteria and Archaea and eukarya are types of eukaryotes. * Archaea are more closely related to eukaryotes. * Prokaryotes have a membrane and nucleoid and most have a cell wall. * There are 3 main types of shapes of prokaryotes: * Bacillus – rod shapes * Spirilum – spiral shaped

A crystal or crystalline solid is a solid material‚ whose constituent atoms‚ molecules‚ or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions. The scientific study of crystals and crystal formation is crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. Potassium alum (Aluminum Potassium Sulfate) is the white crystalline natural mineral salt (double sulfate) of potassium which typically

As the patient was concerned about losing his sight‚ I had to maintain a supportive environment while explaining the need for an Xray and further hospital input‚ without causing him undue stress. I assured him that he would regain sight in his eye and that the trauma had caused temporary blindness only due to the

indeed an efficient and driven researcher. Franklin utilized the X-ray diffraction techniques (that she has become most famous for) while working in a Paris laboratory between 1947 and 1950‚ with crystallographer Jacques Mering. 	X-ray crystallography helped determined the three dimensional structure of DNA when Franklin returned to England. She became the first person to find the molecule¡¯s sugar-phosphate backbone while working with a team of scientists at King¡¯s College in London. Unfortunately

William Perez Cell Biology 2440 Lab on protein Myosin Proteins are chains of amino acids that perform the most important functions in living organism. Every protein will contain an amino group‚ carboxyl group‚ a different R group and an alpha carbon with two hydrogens. There are nine types of functions proteins can have‚ enzymes‚ motor‚ receptor‚ structural‚ storage‚ transport‚ signaling‚ and special purpose proteins(antibodies). There are four levels of protein structure‚ primary‚ secondary

Endoscopy helps in evaluating symptoms such as abdominal pain‚ nausea‚ vomiting‚ bloating‚ diarrhea‚ reflux‚ heartburn‚ bleeding and swallowing difficulty. It is more accurate than Xrays in detecting inflammation‚ ulcers‚ and tumours of the stomach‚ oesophagus and duodenum. Endoscopy also allows the taking of biopsies (small tissue samples) which help in determining a diagnosis. Biopsies can help in detecting infections such as
