Michele Baden Bio 100 – 05 ALLELOPATHY INTRODUCTION The purpose of this lab was to observe the effects of chemical warfare among plants. Plant seeds compete with other plants and seeds‚ for sunlight‚ and nutrients in order to germinate. In order to win dominance over other seeds‚ and reduce competition‚ plants produce and release a chemical in order to prevent other seeds from germination. This type of chemical warfare is referred to as allelopathy. Allelopathy exists in many parts of the plants

encoded by EZH2‚ the EZH2 gene encodes part of the Polycomb group which make protein complexes that help to maintain genes transcriptional repressive state over successive cell generations. http://www.ncbi.nlm.nih.gov/gene/2146 Throughout this lab report template DNA that contains the gene EZH2 was provided‚ this will be amplified by a PCR and cloned into a vector. This Polycomb group proteins help maintain the cell identity during progress through chromatin

After obtaining the pure compound‚ a melting point determination procedure can be done using a mel-temp device to correctly identify the compound if its identity is unknown. In this experiment‚ the identity of a given unknown organic solid will be discovered using the methods of recrystallization and melting point determination. Safety Information • Be sure to add a boiling chip to any liquid before heating it. • Always wear department approved

Capsules are found only in select bacteria‚ and serve a protective purpose. Made out of sugars and proteins‚ they are antiphagocytic‚ which prevents other cells to engulf the bacteria through phagocytosis. It

BIOL 130 Lab Report Identifying Two Macromolecules - Carbohydrates and Proteins 9/26/2013 [Type the company name] INTRODUCTION As the name suggests‚ macromolecules are large molecules that make up more than 90% of the total cell mass. These biological macromolecules vary greatly in size - from several hundred to several hundred million molecular weight units - and are made up of monomer units. There are four major classes of biological macromolecules: proteins‚ carbohydrates‚ lipids

Methicillin Resistant Staphylococcus Aureus Staphylococcus aureus is an important and common pathogen in humans. It is found in the nose or on the skin of many healthy‚ asymptomatic persons (i.e.‚ carriers) and can cause infections with clinical manifestations ranging from pustules to sepsis and death. Most transmission occurs through the contaminated hands of a person infected with or carrying S. aureus. MRSA infections frequently are encountered in health-care settings (Lowy‚ 1998). A common
