The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation‚ the process in which a cell takes up and expresses a new piece of genetic information‚ the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their

Meiossis and Genetic Diversity in Sordaria Meiosis and Genetic Diversity in the Model Organism‚ Sordaria. By: Katie Fiorillo BIO110 Lab TA: Lauren Smith October 30‚ 2012 A. INTRODUCTION: In this lab‚ the organism Sordaria fimicola was used to explore factors contributing to genetic evolution of sexual reproduction. These organisms are found in “Evolution Canyons‚” which occur when two mountain slopes with very different climatic conditions congregate with a comparatively small valley

sale which we are expecting to sell all of them in the school farmer market. Conclusion: The cookies that we made during each lab showed most of the benefits and disadvantages of making our own cookies compare buying commercial cookies (saving money‚ healthier version‚ taste‚ and texture). I believe‚ I can use all these experiences that I gained during each cookies labs at home too. Also‚ it will be helpful and useful in food service. For instance‚ as a register dietitian‚ I can approach any desserts

Introduction: Crayfish also known as Procambarus clariia are classified as a decapod crustaceans related to lobsters‚ crabs‚ and shrimp. They breathe through the gills as they are aquatic animals but they can survive for short time outside the water. They have a hard‚ calcified exoskeleton that must be shed as they grow. In front of the first abdominal segment locates crayfish heart in the dorsal portion of cephalothorax. Crayfish are poikilothermic as their internal temperature is proportional

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that

Research question- What is the rate of temperature change over a period of 30 minutes? Independent variable- time Dependent variable- the temperature of water Controlled variables- the amount of water in the calorimeter - The stop watch - and the thermometer used

The purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions;

This lab specifically does not require the knowledge of what each organism does when introduced to another living organism‚ like a human. Figuring out the type of bacteria could help with further experiments. The idea of the unknown bacteria lab is to show

Experiment 42: Ferrocene Preparation Introduction: The purpose of the lab is to prepare ferrocene from ferrous chloride and cyclopentadiene. Ferrocene‚ an organometallic‚ is a combination of two cyclopentadienide ions with a ferrous cation‚ such that the six pi electrons binds every carbon equally to the metal forming a sandwich type structure. Ferrocene has the properties of both an activated benzene (undergoes electrophilic substitution reactions) and a ferrous ion (oxidation reaction). Glyme
