CHAPTER 2: CELLS Learning about disease is often simplified by growing it in a dish – some cells like heart and nerve cells however do not grow easily outside the body. Cellular reprogramming takes cell back to a state similar to stem cells and then coaxes them to specialize in a different way. Example – LEOPARD syndrome MIM 151100. Acronym for symptoms: enlarged heart w/blocked valves to the lungs‚ freckles‚ abnormal genitals‚ deafness. Skin cells taken from patients were reprogrammed to give

Genomes‚ Transcriptomes‚ and Proteomes 1 1.1 DNA 1.2 RNA and the Transcriptome 1.3 Proteins and the Proteome When you have read Chapter 1‚ you should be able to: Define the terms “genome‚” “transcriptome‚” and “proteome‚” and state how these are linked in the process of genome expression. Describe the two experiments that led molecular biologists to conclude that genes are made of DNA‚ and explain the limitations of those experiments. Give a detailed description of the structure of

Evolution Generally‚ evolution is any process of change over time. In the context of life science‚ evolution is a change in the traits of living organisms over generations‚ including the emergence of new species. Since the development of modern genetics in the 1940s‚ evolution has been defined more specifically as a change in the frequency of alleles in a population from one generation to the next. Darwin ’s theory of evolution describes the descent of all living organisms from a common ancestor

Structures‚ Biosynthesis and Biofunctions of Iron-sulfer proteins Yiming Chen‚ Brown University‚ May 11th‚ 2011 I. Introduction Iron-sulfur proteins are the proteins which contain iron-sulfur clusters‚ like sulfide-linked di-‚ tri-‚ and tetrairon centers with various oxidative states 1. An excess of 120 distinct types of enzymes and proteins are known to contain Fe-S clusters2. Iron-sulfur proteins are known for the role of the oxidation-reduction reactions of mitochondrial electron transportation

Biology Year 11 Yearly Notes Chapter One – A local ecosystem 1.1 Terrestrial and Aquatic Environments -Ecosystem: any environment containing living organisms interacting with each other and with the non-living parts of that environment. -Environment: the environment of an organism is its surroundings‚ both living and non-living -Habitat: the habitat of an organism is the place where it lives. Australian Environments * Terrestrial environments are environments on land. Land covers about

Biodiversity is the degree of variation of life forms within a given ecosystem‚ biome‚ or an entire planet. Biodiversity is a measure of the health of ecosystems. Greater biodiversity implies greater health. Biodiversity is in part a function of climate. In terrestrial habitats‚ tropical regions are typically rich whereas polar regions support fewer species. Rapid environmental changes typically cause extinctions. One estimate is that less than 1% of the species that have existed on Earth are extant

ADVANTAGES OF BIODIVERSITY By adopting a different‚ more positive‚ and more proactive approach to the challenges that environmental issues pose‚ Indian enterprises will greatly benefit in this millennium. The prevalent attitude today‚ with some exceptions‚ is that environmental concerns impose costs that are best avoided. This is natural since these are costs which can fairly readily be externalised and imposed on somebody else. Thus‚ when industrial effluents render river water unfit for drinking

Kindom plantae * Rose A rose is a woody perennial of the genus Rosa‚ within the family Rosaceae. There are over 100 species. They form a group of plants that can be erect shrubs‚ climbing or trailing with stems that are often armed with sharp prickles. Flowers vary in size and shape and are usually large and showy‚ in colours ranging from white through yellows and reds. Most species are native to Asia‚ with smaller numbers native to Europe‚ North America‚ and northwest Africa. Species‚ cultivars
