Abstract:Conjugation is a natural occurring process that involves the transfer of DNA from one cell into another through a physical connection between the cells. In the following experiment‚ two strains of Escherichia coli bacterial cells (donor F’lac+strs and recipient F-lac-strr) underwent conjugation to produce a transconjugant strain (F’lac+strr). MAC plates and streptomycin were utilized to determine if conjugation had occurred. When plated‚ the donor colonies appeared red and the recipient

Protein Article Research Sara Langrell December 15‚ 2011 Nutrition SCI/241 Dr. Venessa Lee Abstract: Athletes have been searching for years for a way to reduce the amount of recovery time between work outs. Based on this issue there has been quite a lot of research conducted to find out what can be done‚ if anything‚ to either reduce or eliminate recovery time. One of the theories is to increase protein intake above the daily recommended amount‚ thereby providing the body with additional

are present in a protein‚ in this case gluten. Introduction: Proteins are large biological molecules that are made up of amino acids. They serve as building blocks that form organic structures such as tendons‚ muscle‚ and cartilage. Enzymes - biological catalysts that allow important chemical reactions to occur in our body - are also made up of proteins. Thus‚ proteins play a fundamental role in the processes of life. [1] Protein purification is basically isolating a protein from complex mixtures

For this kind of scenario‚ I would have to create a server from scratch so I can be able to identify any types of vulnerabilities on any of these server requirements stated below. Any of these can be at risk at any time‚ so creating a new server from scratch would be most recommended. Because it is kind of safer than Windows because most viruses and worms are written for Windows but it doesn’t mean Linux can be attacked. Server Requirements: A Web Server A database server A Simple Mail Transfer

Protein Synthesis Worksheet 1. 2. a. Protein synthesis began in the nucleus. b. Chromatin is a diffuse mass located in the nucleus where genetic material is found. c. A gene is a sequence of nucleotides‚ it is important because they form the template and these templates are used for synthesizing proteins. 3. a. Transcription is the first step of protein synthesis it uses a sequence of DNA nucleotides to produce a sequence of RNA nucleotide. b. RNA polymerase bonds to RNA nucleotides together

the purer the sample is. Since many compounds have similar melting points‚ a mixed melting point can be taken by mixing samples of the unknown with an authentic sample of the known compound and taken the melting point of the mixture. In this experiment‚ unknown #26 had a melting range of 154°-155°C. After looking at known melting points‚ we expected the unknown to be citric acid. While determining the melting point of the authentic citric acid sample‚ we got a melting range of 153°-160°C. The

Experiment 12: Calorimetry and Hess’s Law Purpose: The purpose of this lab is to determine the enthalpy of reaction for the burning of one mole of magnesium in oxygen. Although the reaction is exothermic‚ the ∆HRXN will be determined by using calorimetry and then using Hess’s Law to manipulate the data collected to yield the answer needed.
