INTRODUCTION Microbes are those microscopic organisms that can cause diseases in the human body. These microbes migrate with locomotive organelles called FLAGELLA, a very vigorous nanomotor that is highly conserved across bacterial species. Flagella allow the microbes to move towards favourable environments. Further studies on flagella has revealed that it not only serves the purpose of locomotion but also plays a very crucial role in bacterial pathogenicity(14). A flagella has mainly three…
identity gives way to knowledge, to better understanding and access to information on how an organism works and how we can prevent its worsening effects or isolate its benefits. Scientists have been trying to discover and study different strands each and every day to keep up with the future’s demands for medicine and cure mainly because we are all susceptible to diseases. People that study these organisms use different techniques to reveal the identity of…

Engineering – How far will we go? We are living in a world which is changing with an exponential pace; every day humans are creating new inventions, gathering new knowledge about scientific phenomena and starting new empirical projects. Genetic engineered organisms are yet part of our life on a daily basis, even though we do not recognize it as that. Already today there are heated debates about how far we should go with genetically modified plants or animals. In the future, perhaps just a couple…

reproduction of the organism that is most likely to thrive. Sexual reproduction takes the DNA from both the male and the female and passes it down to the offspring. In this passing of DNA, mutations are normally expected. These mutations can be positive or negative to the survival of the organism. Sometimes the mutations do not affect the organism positively or harmfully at all. However the organisms that inherit the mutation that enhances their ability for survival, are the organisms that are…
Genetic Engineering is the modification of an organism 's genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. With this new, rapidly growing, technology we are now able to do things that we once thought were impossible. In Ethics and the New Genetics, the Dalai Lama addresses problems that we need to consider as we continue to explore this microscopic world that we have…
The aim of the data analysis exercise was to determine genetic relationships between the HSP70 amino acid chains of fourteen different organisms. The data produced was an identification table, a sequence alignment diagram and a cladogram. In cladograms the branches are not representative of the evolutionary time that has occurred. Heat shock proteins (HSPs) are in a class of proteins called molecular chaperones. (Kiang, J.; G, Tsokos. 1998). They are present in both eukaryotes and prokaryotes,…
Safety in the science classroom involves weighing the potential risk factors of an experiment against the educational value, teacher and student should have a full understanding all the potential hazards of the materials, the experiment, and the equipment used. Safety concerns and potential hazards should be addressed prior to engaging in any laboratory activity and documented in the lesson plan. Students should be aware of the emergency contact sheet with phone numbers that is attached to the…
Without biodiversity, how different would the world be? Biodiversity is arguably the basis for all living things. Without it, many experts believe that there would be no living organisms on the Earth. Biodiversity is the variety in all living organisms in certain ecosystems or habitats. Sustainability can be defined as meeting the needs of the current generation without risking the needs that the future generations will need. Without biodiversity, sustainability would not be possible whatsoever.…
