    sulfur and protein contains sulfur but very little phosphorus. Hershey and Chase injected bacteriophages in an organism. When the bacteriophage was injected with sulfur it didn’t show the genetic material as a protein, but when injected with phosphorus the bacteriophage obtained a radioactive reaction. The primary factor is that DNA contains no sulfur and proteins contain no phosphorus. thus, since the bacteriophage is just made of a protein capsid and DNA enclosed on, can label either as…

  • Wastewater Pollution Essay

    BACTERIOPHAGE MEDIATED PHYTOREMEDIATION Wastewater is any water that is against the usage by human . Wastewater is the result of domestic, commercial, industrial or agricultural activities. After the use water is returned to the environment in a different condition, usually as dirty water (wastewater).It is never returned in the same way as it was withdrawn. Wastewater produced by households or communities is also called municipal wastewater or sewage. (Tilley) Effluent refers to the sewage or…

  • Viruses Cause Diseases

    Viruses are nonliving, microscopic organisms that cannot be seen with the naked eye. Since they do not have the ability to replicate by themselves, viruses must rely on a host organism which allows the virus to multiple. This is why they are often referred to as cellular parasites. Since they are very small, and they can only be seen by looking through a microscope. There are approximately 5,000 different viruses that have the potential to infect plants, animals, and bacteria. Some are…

  • Dna Is Hereditary Material Essay

    process to see how it would react with the phage. From doing this they discovered protein coats that protect the DNA, and found that the DNA was not absorbed to the phage bacteria. They then experimented with the process of thawing and freezing the bacteriophage and discovered that the DNA is more sensitive to the DNAse when no growth is taking place. Hershey and Chase then, proceeding in the direction of infecting cells, used the blender experiment to suspend these infected cells. From this…

  • Genetic Reflection Paper

    The material covered in my genetics class helped me better understand the article, How Spiders Got their Knees, by Emily DeMarco. For example, the article describes how the Dachshund gene was duplicated and activated in the patella region which formed kneecaps, providing flexibility (DeMarco, 2015). In class I learned about the different types of errors that can occur during DNA replication and repair. I learned that duplication can occur through replication slippage or unequal crossing over.…

  • Sulfolobus Acidocaldarius: The Ultimate Social Network

    Sulfolobus acidocaldarius is an Archaean extremophile. This strictly aerobic prokaryote is found in the searing temperatures of sulfur-rich geothermal hot acid springs, geysers, and deep ocean vents. While primarily an aquatic organism, S. acidocaldarius can also be found in hot acidic soils. Optimal conditions for S. acidocaldarius included a temperature of 80°C and a hydronium ion concentration, pH, of 2; making them acidophiles (acid loving) and thermophiles (heat loving). (Wikipedia #2). As…

  • The Hershey-Chase Experiment

    minds of the scientific community. Others would demonstrate their findings in different experiment years after through experiments such as the Stahl experiment in 1958. Many believed that proteins did as they looked far more complex than DNA.The bacteriophages also demonstrated that when they infect a bacterium with their genes. The DNA will come out but very little protein will. It would later become known as the blender experiment for the use of a blender to empty viral protein shells from the…

  • Agarose Gel Electrophoresis: Case Study

    Lambda comes from a bacteriophage, but is harmless to humans and other eukaryotic organisms. Lambda has approximately 48,000 base linear pairs. Three common restriction enzymes: EcoRI, HindIII and PstI are used to separate the DNA fragments. The task at hand was to separate the…

  • The Pros And Cons Of Phage Therapy

    Phage therapy has been a debated for many years. The discovery of bacteriophages in the 20th century by Frederick Twort and Felix D’Herelle led to contributions of many fields in science [1]. Such contribution can lead to curative methods for bacterial infections. Antibiotics are primarily the source to help with infections, but phage therapy has been in discussion for an option to replace antibiotics. The reason why it has been debated is that the limitations of phages due to its biological…
