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

There are several methods to test syneresis. Acid curds need to be formed in a glass beaker which make it easier to transfer the curds into syneresis test installations. All curds must be transferred carefully into the device‚ otherwise some soft curds were easily broken and the results would be affected. In case that some of the gel were not easily removed with the sample residues on the bottom of the beaker when transforming‚ beakers can be pre-coated with paraffin wax on the inside. Both a barrel-shaped

| Gram Negative Unknown | Biology 3444-006 | | Lena Wallace | 11/7/2011 | | Abstract: The purpose of this lab was to identify an unknown bacteria culture using differential tests. The identification of the unknown culture was accomplished by identifying the bacteria based on its specific metabolic characteristics and morphology. It is suggested that culture 11 is a sample of Enterobacter aerogenes. Introduction: This experiment was centered on metabolic and biochemical testing

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

Titration Lab Introduction The purpose of this lab is reach and be able to calculate the equivalence point when we use titration to neutralize a base with acid. The process of the lab was determining the volume of a solution needed to react with a given mass or volume of a sample is called titration. The equivalence point is when the same number of moles of acid and moles of base has been added. Phenolphthalein is used as an indicator because it will have a color change when the equivalence point

blessed with biodiversity composed of prokaryotes and eukaryotes. Almost all of them have specialized systems of sensing light‚ sensory and/or motor response composed of a cell‚ tissue or organ like eyes and brain. The Pax (Paired box) genes and proteins have been observed critical during formation of such tissues or organs and Pax family transcriptional regulators remain critical to maintain their functional anatomy. The Paired Box 6 (Pax6) best exemplifies the conservation of functions through

CHARACTERIZATION OF PROTEINS Abstract Different techniques and principles for protein extraction and characterization were demonstrated in this experiment. Various proteins were extracted from different sources: 1.67 g yeast invertase‚ 1.03 g egg white albumin‚ and 5.15 g of milk casein. Activity assay for invertase was performed using Benedict’s test and the enzymes inverting action on sucrose was confirmed. Warburg-Christian Method and Bradford Assay were also employed to determine the protein concentration

Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:
