  • Similarities Between Bacterial Viruses And Archaea

    living host. Once it invades a host (a bacteria 's body), it acts as a parasite. It uses the bacteria 's metabolism to develop and grow. Meanwhile, it destroys the bacteria by disintegrating the cell 's membrane. This process is known as bacteriophage (bacteriophage, 2003). When a bacterial virus enters an insect, animal, or human, it can transform into what we call a bacterial infection. Bacterial viruses could spread but would never become an infection if it did not enter a living organism…

  • Antimicrobial Resistance And Antibiotic Resistance

    The ways in which bacteria can become resistant to antibiotics and how this contributes to the global healthcare concern of Antimicrobial Resistance (AMR). Antimicrobial resistance is a prevailing issue since the discovery of the first antibiotic Penicillin in 1928. There are 5 mechanisms which allow resistance to impede new antibiotic development for the last 29 years (WHO, 2016) consisting of mutations in target genes, enzymatic resistance, latency, antibiotic efflux and non-specific mutations…

  • CRISPR-Cas9 System: A Genetic Analysis

    bacteria and archaea against bacteriophage infection. It was first reported as part of the genome of Escherichia coli and, during the next years, other bacteria and archaea were reported to also present the CRISPR cluster. Cas genes were reported to be conserved in these organisms as well. Basically, CRISPR consists of CRISPR-associated genes (Cas genes) and the CRISPR array, which is a series of direct repeats and spacers that correspond to the nucleic acids of the bacteriophage. In this…

  • Antimicrobial Resistance

    1. Introduction Antimicrobials have proved to be one of the most successful medicinal discoveries in history, principally because they have turned bacterial infections which were once the leading cause of death, into controllable conditions.[1, 2] These molecules inhibit the reproduction, prevent vital processes occurring, or destroy the bacterial cell wall to aid in fighting infectious diseases.[3, 4] Antimicrobial therapy is one of the foundation stones of modern medicine, and without…

  • The Effects Of Gmo's On The Environment

    To accurately understand the effects of GMO’s on the environment, it is important to first understand what a GMO is and how it changes the identity of the organism. A GMO is a genetically modified organism, this means that the genes of one specific organism are extracted and implanted into a new organism, or that the DNA has been altered and modified (live science). According to conventional breeding, we know that the parents of the individual both give half of the genetic material within the…

  • Antibiotic Protestant Bacteria Research Paper

    ) Discuss antibiotic resistant bacteria, cause and effect. Antibiotic resistant bacteria is a big concern now a day due to the use of excessive and improper use of antibiotics. It is very common for people to star taking an antibiotic and stop the regimen as soon as the symptoms are gone. With this practice, bacteria that were not killed by the antibiotic but were exposed, are capable of becoming immune to it. This immunity or resistance can be passed on from bacteria to bacteria through the…

  • Frederick Griffith's R-Strain

    In the 1920s, A British researchers named Frederick Griffith studied bacterial pneumonia to find a vaccine for it. The specific bacteria was Streptococcus pneumoniae. Using streaking on a cultured Petri dish, the batterie was seperated into two strains, or colonies. The R-Strain was rough, and when injector into mice, it did not cause pneumonia, but the S-strain was smooth and slimy, and caused lethal pneumonia when injected. When the S-Strain was killed by heat, it did not cause sickness, but…

  • Essay On Recombinant Dna

    Advances in biology have led to many life altering medications, treatments, and solutions to molecular issues. One such region of biology that has altered scientists’ stances on creating a perfect product is the research being done on recombinant DNA. Recombinant DNA is any single molecule containing DNA sequences from two or more organisms. The process of creating recombinant DNA relies on the use of restriction enzymes, gel electrophoresis, and DNA ligase. The first step in creating this new…

  • Comparison Of Malaria And Plasmodium Parasites

    coli. (Ishino et al., 1987) CRISPR are sections of prokaryote DNA with short repeating sections of base sequences, interspaced by foreign Spacer DNA from exposure to a bacteriophage virus. (Marraffini and Sontheimer, 2010) CRISPR is a natural process that occurs in bacteria as a defence mechanism. Bacteriophages hunt and kill bacteria by inserting their genetic code into the bacteria. This kills the majority of bacteria, however, any survivors capture the Viral DNA which confers an immunity…

  • Literature Review: Green Fluorescent Protein And Histidine Tagged Proteins

    Literature Review: Green Fluorescent Protein and Histidine Tagged Proteins Histidine and green fluorescent protein (GFP) tagging are important in molecular biology because they allow for purification, tracking, and quantification of target proteins (Ferrari et al., 2004; Cho et al., 2011; Deponte, 2012). Histidine tagging provides a method for isolating and increasing the amount of target protein recovered from a biological organism or mixed sample of proteins (Masek et al., 2011; Singh and…
