Introduction - sickle cell anemia The first suggestion that genes might provide the information for all proteins came from Linus Pauling’s lab at Caltech. He and his student Harvey Itano studied hemoglobin‚ the protein in red blood cells that transports oxygen from the lung to metabolically active tissues‚ like muscle‚ where it is needed. In particular‚ they focused on the hemoglobin of people with sickle-cell disease‚ also known as sickle-cell anemia‚ a genetic disorder common in Africans‚ and

Nguyen 1 Jenny Nguyen November 25‚ 13 Diane Putnam Parasite Is Worst Than Having A War Ever wonder why we get sick? Most people believe it ’s because of "germs" but it ’s actually humans and other organisms that are constantly under attack by parasites. Parasitism is a kind of harmful coaction between two species. It is a relation between two individual called host. Parasite is mainly a food coaction‚ but the parasite derives shelter and protection from the host. Parasites are intelligent

MICROBIOLOGY SECTION The microbiology section aims at studying yu ailments and diseases from the isolation of suspected causative organisms. The processes involved in the isolation of these organisms include; culturing‚ staining‚ microscopy and sensitivity tests. Samples collected for examination include; stool‚ blood‚ sputum‚ urine‚ vaginal swab‚ wound swab and wound biopsy. Bacterial Culturing and sensitivity Cultures are carried out to isolate suspected organisms from a sample. There are different

Option F: Microbes and Biotechnology Diversity of Microbe F.1.1 Outline the classification of living organisms into three domains. Three domains of living organisms: 1. Archaea - very primitive; live in extreme habitats 2. Eubacteria - more advanced 3. Eukaryota - all life forms with eukaryotic cells (have a nucleus) Use of ribosomal RNA sequences for classification rRNA is found in all cells rRNA is easy to isolate Analyzed to determine the exact sequence of nucleotide bases

sporozoites then move into the salivary glands where they prepare to infect another host Transmission: Malaria is transmitted through vectors. They could be animals or insects such as female Anopheles mosquitos. These vectors carry an organism called plasmodium which is the actual cause of the disease which is spread around by the vectors. Worldwide importance: Malaria is an important disease because it is in fact

Classification of species: kingdoms contain many different types of organisms‚ each taxon contains progressively fewer types of organisms‚ taxon “species” is narrowest category‚ containing only one type of organism. As you go from kingdom to species‚ organisms share more and more in common. - Explain and give an example
