Antibiotic resistance In recent years a challenge to the effective treatment of an ever-increasing range of infections caused by microbes is antimicrobial resistance (AMR). AMR results in reduced effectiveness of antibiotics‚ making the treatment of patients very difficult and sometimes impossible. The impact on especially susceptible patients is most evident‚ resulting in prolonged illness and increased mortality. The total problem caused by AMR on medical field in general and healthcare sector

DNA replication is a biological process that occurs in all living organisms and copies their DNA; it is the basis for biological inheritance. The process starts when one double-stranded DNA molecule produces two identical copies of the molecule. The cell cycle (mitosis) also pertains to the DNA replication/reproduction process. The cell cycle includes interphase‚ prophase‚ metaphase‚ anaphase‚ and telophase. Each strand of the original double-stranded DNA molecule serves as template for the production

DNA DIGESTION AND ELECTROPHORESIS In this experiment we will be doing a process called as DNA digestion or also known as restriction digest. A restriction digest is a procedure used in molecular biology to prepare DNA for analysis or other processing. It is sometimes termed DNA fragmentation‚ scientists Hartl and Jones describe it this way: This enzymatic technique can be used for cleaving DNA molecules at specific sites‚ ensuring that all DNA fragments that contain a particular sequence have the

Title______________________________________________________________________ Influence of Rhizobium on the growth and yield of Rice Abstract___________________________________________________________________ Rice (Oryza sativa L.) is one of the world’s most important crops. The present investigation was designed to assess the range of growth-promoting activities of various diazotrophic bacteria on rice seedling vigor‚ its carryover effect on straw and grain yield‚ and the persistence of an

For the preparation of the filtrate solution at the beginning of the class our Instructor‚ Marshall Douglas added about four to five strawberries in the blender along with 100 ml of detergent/ enzyme/ salt solution. They were blended until thoroughly homogenized if foaming occurred more detergent solution was added to prevent it. Then the blended solution was poured into a beaker and left to incubate at 60C for 15 minutes. Also‚ the mixture solution was cooled on ice for 5 minutes and filter through

Microorganisms are tiny‚ small living things which can not be seen with eyes. They spread everywhere around the 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

The Rise of Antibiotic-Resistant Infections by_ Ricki Lewis‚ Ph.D._ When penicillin became widely available during the second world war‚ it was a medical miracle‚ rapidly vanquishing the biggest wartime killer--infected wounds. Discovered initially by a French medical student‚ Ernest Duchesne‚ in 1896‚ and then rediscovered by Scottish physician Alexander Fleming in 1928‚ the product of the soil mold Penicillium crippled many types of disease-causing bacteria. But just four years after drug

The Expression and Purification of Recombinant Green Fluorescent Protein (rGFP) From E. coli strain‚ BL21(DE3)‚ Using Ni2+-Agarose Affinity Chromatography Abstract: The purpose of these series of experiments was to express and purify recombinant Green Fluorescent Protein (rGFP) from the E. coli strain‚ BL21(DE3) by beginning with its purification via a Ni2+-agarose affinity chromatography column. The His6 tag of the rGFP bound to the Ni2+-agarose column and washes and elutions were obtained
