Honors Enrichment Questions Week 3 What are chemotherapeutic drugs? Research two and explain how they work against cancer. Chemotherapeutic drugs are used during chemotherapy and are a treatment for cancer. Leustatin- used for hairy cell leukemia, chronic lymphocytic leukemia, and non-Hodgkin’s lymphomas. It is an …

Introduction The utilization of any complex molecule for energy by an organism is dependent on a process called hydrolysis. Hydrolysis breaks complex molecules into simpler molecules using water. Similarly, the process that is the reverse of this is called dehydration synthesis, which removes water from …

Introduction Bacteriophage which is also known as bacteria eater refers to viruses that infect bacteria.Bacteriophages are known to only replicate within host cells and must attach to a specific receptor on the surface of a bacteria cell to initiate infection. The contact between the phage …

A prospective, randomized and comparative study of oocyte survival by slow freezing and vitrification methods. Dr. Suresh Babu Chaduvula, Abstract: Aim and Objectives: To determine the efficacy of slow freezing and vitrification methods in the survival of oocytes. Introduction: Material and Methods: It is a …

Define metabolism: The sum of all biological chemical reactions inside a cell or organism Differences in catabolism and anabolism: Catabolism is an enzyme-regulated chemical reaction that releases energy. Complex organic compounds such as glucose, amino acids, glycerol and fatty acids are broken down into simpler …

Different types of bacteria in various forms are found all around us, and it is a microbiologist’s job to be able to identify these bacteria. Using various staining techniques and physiological tests, an isolated bacterium can be identified. In this experiment, a single bacterial colony …

Introduction The World Heath Organisation (2011) estimates that without intervention 84 million people will die from cancer between 2005 and 2015. In 2008 156,723 people died in the UK alone of malignant neoplasm and 1 in 3 people will be diagnosed with the disease in …

Genetic transformation is due to a direct cause in the change by genes, due to the cell in taking and expressing traits from a separate piece of DNA. Naturally proficient bacteria are able to absorb exogenous DNA and go through genetic transformation. (Chen & Dubnau, …

Genetic manipulation has produced some potential advantages to be able to alter the cells in animal models of human diseases, which may make disease as a thing of the past and help with the development of better pharmaceutical products in order to extend the human …

So why are we seeing a dramatic increase in allergies? Some health experts believe that it could be, in part, due to the recent introduction of genetically modified (GM) foods. If evidence from around the world is anything to go by, there may be a …
