Escherichia coli and Staphylococcus albus Some bacteria’s require a certain amount of light in order to function properly and there fore survive. Escherichia coli is found in the gut and intestines of mammals. Staphylococcus albus is generally a skin dwelling bacteria Aim: To test whether the amount and type of light that the bacteria’s E.coli and S.albus are subject to causes changes in their growth rates and habits. To test whether the growth rates and habits of the bacteria’s E. coli and S

DNA profiling is a method of identifying an individual by unique characteristics of their DNA. A specific DNA pattern‚ called a profile‚ is obtained from an individual or a sample of tissue. This allows the comparison of the base sequence of two or more DNA samples to determine whether they are related. DNA profiling has many uses‚ in prevention of economic fraud‚ dietetic work‚ and classifying species‚ identifying bodies‚ forensic science‚ screening for disease‚ and investigating paternity.

Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here

it can be used. If we go back to the slide of the double stranded DNA‚ and if we take that to a high temperature‚ the two strands separate‚ you then add the primers‚ which interact with ? On the strand‚ synthesis takes place in the 5-3 direction‚ then you end up with 2 molecules identical to the DNA‚ and then you do another round‚ so it’s an exponential increase. There are different enzymes and polymerases‚ which come from bacteria and hot springs. The original polymerase is the taq polymerase

The upper most strand is the (coding strand) DNA base sequence (triplet) of the gene codes for synthesis of a particular polypeptide chain. The second strand is the mRNA base sequence (template strand used for copying) codon of the transcribed mRNA. The process for going from the upper stand to the second strand is called Transcription and involves an enzyme called polymerase. The polymerase attaches to the promoter region (start codon) and reads the nucleotide base sequence until it gets to a termination

lifeless objects that humans call their own creations with the intent to embody the technological genesis of a world that will soon consume the future of time. When comparing Joseph Kosinski’s post-apocalyptic‚ Oblivion‚ and Jim Morris’ animated film‚ Wall-E‚ similarities between both struggling protagonists are revealed‚ leading the reader to realize that the human instinct of survival has evolved into an impulse for humans to forge a world of their own‚ though when humans periodically forget to reflect

2.3.3 Feature Extraction Feature extraction deals with the extraction of the distinctive features out of face images so that those face images can be differentiated among each other. There are several algorithms available for extracting features out of a face image. The most common is the use of mathematical formulas that generate a mathematical representation of a face image that is termed as a template‚ these templates are “the refined‚ processed and stored representation of the distinguishing

From Cell phone to Smart Phone Over the years‚ technology has grown immensely. With the touch of a button‚ you can be talking‚ video chatting‚ or even messaging someone from another city‚ state‚ or country. Technology has made it easier for families and friends to keep in touch on a regular basis without having to pick up a pen‚ or licking a stamp. It has made communicating as simple as getting a glass of water. Technology made communication an important part of our lives without us

Eukaryotic Cells Worksheet Provide a list describing at least three differences between prokaryotic and eukaryotic cells: 1. While Prokaryotes contain just one copy of each gene‚ eukaryotic cells have two. For such reason‚ prokaryotes are known as haploid and eukaryotic as diploid. 2. While Prokaryotes see some nonessential genes being encoded into extra-chromosomal plasmids‚ such activity is typically absent in Eukaryotic cells. 3. The own way DNA is present in each type of cell has different
