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

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

number of paper towels throughout the experiment. Most of the seeds had germinated in the paper towels. The one outlier that was strange was the one paper towels. Only 14 of the 15 seeds germinated in that group. The difference that we could observation was the healthiness of the plants. IV. Conclusion Paragraph 1 Recap (Evidence): The purpose of our lab was to see if the amount paper towels would affect the germination of the seeds. My hypothesis was‚ if I increase the amount of paper towels

the percent yield by dividing the expected yield‚ the amount of product that should be produced based on your stoichiometric calculations‚ by the actual yield‚ the amount of product that is experimentally obtained from a chemical reaction. In this lab‚ I have determined the reaction for mixing two reactants together; I measured out 0.005 moles of each reactant‚ lead (II) nitrate and potassium chromate. I dissolved‚ mixed‚ and made them react to make products; I compared the mass of the two reactants

zmosis The IB Lab Report Measuring osmosis 1. Introduction My experiment is about osmosis on a potato and if or the quantity of salt affects osmosis. I would do the experiment with 5 potatoes cut into squares all the potatoes weight the same so the weight can`t be a variable the I put the potatoes on 5 different plastic cups with different amounts of salt and then I weight them again to see if the quantity of salt affected the osmosis of potatoes 1a. Research question ¿Does the quantity

Maria Martinez Anatomy and physiology II TTH 2:20 “Demonstrating the Importance of Surfactant: Lab Report” Introduction Surfactant is an essential component for the respiratory system to function properly. This experiment was administrated to help us understand better the role of surfactant in the alveolar system. Surfactant is a detergent-like substance produced by the Type II alveolar cells in the alveoli. Surfactant is produced to make it easier for people to breath by reducing the surface

Termite Lab Report The effect of ink on termite behavior Abstract Termites produce special chemicals within their bodies called pheromones. Because termites are usually found inside dark areas‚ pheromones help them communicate in these places. Past studies have suggested that ink inside ballpoint pens contains pheromones‚ causing termites to follow any trail created by the ink. If a pathway is drawn with an ink pen‚ then a termite will be attracted to the path and trace it due to the pheromones
