Pharmaceutical Science Year 2 Date: 7th- 14th of February 2014. Title: Ligation of Lambda DNA pre-digested with EcoRI and HinDIII. Restriction of Lambda DNA with restriction enzymes. Aim: The objectives of this experiment are: Become more familiar with using micropipettes. Use restriction enzymes to cut DNA at specific sites. Use Ligase to rejoin some of the cut/separated DNA fragments. Learn to separate DNA using electrophoresis. Introduction: Restriction

multiplicative effect; a cell with four or five independent restriction enzymes could be virtually impregnable. Among the first restriction enzymes to be purified were EcoRI and EcoRII from Escherichia coli‚ and HindII and HindIII from Haemophilus influenzae. These enzymes were found to cleave DNA at specific sites‚ generating discrete‚ gene-size fragments that could be re-joined in the laboratory. Researchers were quick to recognize that restriction enzymes provided them with a remarkable new

Introduction Identification and classification of bacteria is important to make easier manipulation on the bacteria for various purposes such as for medical‚ research‚ developmental‚ and biotechnicalfieldsThe cell wall is the basis for classification of bacteria according to the Gram stain. Accordingto the chemical make up of bacterial cell wall‚ a staining procedure‚ Gram stain‚ helps usclassify bacteria into two subgroups‚ The cell wall can stain either positive or negative‚depending on its chemistry

Introduction The purpose of this persuasive essay is to take a position on the topic; Compulsory immunisation for all Australian children and the issues linked to compulsory immunisation. Firstly the persuasive essay will define and immunity; following this relevant diseases to immunisation will be discussed. Finally the essay will explore the major arguments associated with compulsory immunisation for children. Immunisation The immunisation is the process of protection against harmful diseases
