referred to as bacterial transformation and is caused by the alteration of a cell‚ which results in the uptake and expression of foreign DNA. Transduction is the process by which DNA from one bacterium is transferred to another bacterium through a virus‚ which infects one taking genetic information and then the other‚ depositing the genetic information. The final way HGT occurs is though a process known as conjugation. Conjugation is a form of bacterial “mating” which results in the sharing of genes

I have infected 45 million Americans and will infect 1 million more Americans each year. Who am I? Herpes‚ from the ancient Greek meaning to creep or crawl‚ is the name of a family of viruses of which herpes simplex virus 1 and herpes simplex virus 2 (HSV-1 and HSV-2) are the most serious human pathogens. HSV-1 is normally associated with orofacial infections and encephalitis‚ whereas HSV-2 usually causes genital infections and can be transmitted from infected mothers to neonates. Both viruses

DNA is the “blueprint” for the individuality of an organism. The organism relies upon the information stored in its DNA for the management of every biochemical process. The life‚ growth and unique features of the organism depend on its “blueprint”. The parts of DNA which have been linked with specific features or functions of an organism are called genes. Molecular biologists have discovered many enzymes which change this structure in living organisms. Some of these enzymes can cut and join strands

Colloidal silver has become increasingly popular for several good reasons. It is very affordable‚ especially if you make your own with a generator. It can treat hundreds of illnesses. And this liquid is also very safe. Read on to find out more about colloidal silver and all its benefits. What is Colloidal Silver? Colloidal silver is a suspension of distilled water that contains nanoparticles of silver. It can be made to be different strengths‚ so it can be tailored to the severity of the illness

How can we tell if an organism is alive or not? Is a virus ‚ prion‚ virod‚ or a rock a living organism? What is life? Biologist have studied what makes organism alive for many years and have come to the conclusion the there are nine characteristics of life. Each characteristic has a property which applies to how and organism is alive. Life characteristics are as follows: order‚ metabolism‚ motility‚ responsiveness‚ reproduction‚ development‚ heredity‚ evolution‚ and adaptation. All of the characteristics

are becoming more resistant. The main advantage of phage treatment is the specificity of bacteriophages. These viruses can be designed in a lab to specifically target pathogenic bacteria. One benefit of phage treatment includes the ability of the virus as it does not negatively affect the normal microbiota in your body. One potential issue with phage-therapy is that some phages has an ability to modify host bacteria in ways that could make them more pathogenic. According to NCBI‚ phage therapy excludes
