  • Dna Fingerprinting - 1,017 words
    Dna Fingerprinting DNA Fingerprinting DNA Fingerprinting is also referred to as DNA profiling and DNA typing. It was first developed as an identification technique in England in 1985. The original use was to expose the presence of any genetic diseases. About three years later it became used to identify criminals through the analysis of genetic material and to settle paternity disputes. It is still used for those reasons today. The DNA fingerprinting process is called gel electrophoresis. It is a process that can sort pieces of DNA according to its size. The process is done by taking samples of DNA from the crime scene and comparing it with samples from the accused. Samples are taken from bio ...

  • Dna Separation By Electrophorosis - 565 words
    DNA Separation By Electrophorosis DNA, Deoxyribonucleic acid, is a double stranded, helical nucleic acid molecule which determines inherited structure of a protein. The "steps" are made of bases: adenine, guanine, cytosine, and thymine. The sides are sugar and phosphate molecules. Restriction enzymes are enzymes that cut DNA at restriction sites, leaving fragments blunt or sticky. The restriction fragments are separated using a technique called gel electrophoresis. DNA has a negative charge so when an electrical charge is applied it makes DNA move to the positive side. DNA is placed in agarose gel. Smaller fragments move faster. The purpose of this lab is to separate DNA fragments using gel ...

  • Electrophoresis Separation Of Proteins Cytochrome C, Myoglobin, Hemoglobin, And Serum Albumin By Using Isoelectric Focusing S - 1,418 words
    Electrophoresis Separation Of Proteins Cytochrome C, Myoglobin, Hemoglobin, And Serum Albumin By Using Isoelectric Focusing System (Ief) Electrophoresis Separation of Proteins Cytochrome C, Myoglobin, Hemoglobin, and Serum Albumin by Using Isoelectric Focusing System (IEF) Introduction Proteins are composed of amino acids. All amino acids are amphoteric molecules consisting of three types of amino acids: neutral, acidic, and basic. Thus, for any protein there is a characteristic pH, called the isoelectric point (pI), at which the protein has no net charge and therefore will not move in the electric field. Electrophoresis takes advantage of this characteristic. Proteins are electrophoreased, ...

  • What Is The Human Genome Project - 1,297 words
    What is the Human Genome Project? The Human Genome Project (HGP) is an international research program designed to construct detailed genetic and physical maps of the human genome, to determine the complete nucleotide sequence of human DNA, to localize the estimated 80,000 genes within the human genome, and to perform similar analyses on the genomes of several other organisms used extensively in research laboratories as model systems. This project is estimated to take 15 years to complete from October 1990 and has already cost the U.S. 2.5 billion dollars. The scientific products of the HGP will comprise a resource of detailed information about the structure, organization and function of huma ...
