Plasmids serve as important tools in genetics and biotechnology labs‚ where they are commonly used make many copies of a particular gene. The aim of this experiment was to identify three mystery plasmids based upon their characteristics; such as size‚ antibiotic resistance‚ lacZ profile and conjugative properties. The results obtained showed that plasmid number2 was the pDSK519 plasmid and its size was 26229.58 Bp. Plasmid pDSK519 also was found to be resistant to kanamycin only and it possessed the LacZ

world. Most people think that microorganisms are harmful to the environment. Humans exploit these small living things hundreds of years ago. Science has developed and scientists have established new science related to microorganisms‚ it is called microbiology. In this essay‚ I will talk about one of the oldest and most widespread microorganisms in our planet‚ bacteria. Bacteria lives everywhere‚ in air‚ hot springs‚ and in our bodies. Some bacteria are harmful and some of them are helpful. Biologists

Introduction To date‚ the bacterial resistance to antibiotics is one of the most important global health threat introduced by the World Health Organization (WHO) and most annual mortality due to hospital infections occurs because of this challenge (1). According to the US Centers for Disease Control and Prevention (CDC) report‚ carbapenem-resistant Enterobacteriaceae (CRE) are one of the three main antibiotic resistance threats. (2). Enterobacteriaceae are Gram-negative bacilli which cause a wide

Borrelia burgdorferi Overview: Lyme disease was first recognized in the United States in 1975 by Dr. Allen Steere‚ following a mysterious outbreak of juvenile rheumatoid arthritis near the community of Lyme‚ Connecticut. The rural location of the Lyme outbreak and the onset of illness during summer and early fall suggested that the transmission of the disease was by an arthropod vector.

Title: Investigation of Induction Time of lac operon in E. Coli with IPTG‚ and Comparision of the Amount Beta-galactosidase produced with Lactose‚ IPTG and Antibiotic. Abstract: Introduction: An operon is a group of genes that are arranged side by side with a regulatory gene. It also includes a promoter gene‚ operator gene‚ structural genes. Regulatory genes control transcription with positive or negative signal. (Jacob‚ and Monod‚ 1961) A positive signal‚ inducer‚ would stimulate

Histoplasmosis There are many different types of disease that affect different systems of the body. Most of them can be treated and cured with antibiotics. One disease that affect the respiratory system is histoplasmosis. This disease is caused by inhaling spores of a fungus called Histoplasma capsulatum. Even though diseases can be dangerous this one is not contagious because it can not be transmitted from an infected person or animal. Histoplasmosis affect a person’s lungs. The symptoms

An Introduction to Probiotics Probiotics are live microorganisms (in most cases‚ bacteria) that are similar to beneficial microorganisms found in the human gut. They are also called “friendly bacteria” or “good bacteria.” Probiotics are available to consumers mainly in the form of dietary supplements and foods. They can be used as complementary and alternative medicine (CAM).1 To find out more about topics and resources mentioned in this fact sheet‚ see “For More Information.” Key Points
