Each restriction enzyme is named based on the bacterium in which it was first identified. EcoR1 was purified from Escherichia coli. Hind111 was the third enzyme that was isolated from Haemophilus influenza. These enzymes are used to manipulate and analyze DNA sequences. Each of the three restriction enzymes used has a particular restriction site. Restriction mapping is the process of cutting DNA at specific sequences with restriction enzymes

Chancroid‚ also know as Haemophilus Ducreyi‚ is a bacterium that attacks the skin tissue and produces an open sore. The sore appears in the region of the reproductive organs. The chancroid bacterium appears in both men and women. The symptoms of chancroid may vary between gender but nonetheless appear a few weeks after initial exposure. In men a small red bump will form near the genitals and convert to an open sore only a day or two later. For women four red bumps form in the genital region and also

The Human Genome Project (HGP) is a project undertaken with a goal to understand the genetic make-up of the human species by determining the DNA sequence of the human genome and the genome of a few model organisms. The project began in 1990 and‚ by some definitions‚ it was completed in 2003. It was one of the biggest investigational projects in the history of science. The mapping of the human genes was an important step in the development of medicines and other aspects of health care. Most of the

What Are STDs? STDs are sexually transmitted diseases. This means they are most often -- but not exclusively -- spread by sexual intercourse. HIV‚ chlamydia‚ genital herpes‚ genital warts‚ gonorrhea‚ some forms of hepatitis‚ syphilis‚ and trichomoniasis are STDs. STDs used to be called venereal diseases or VD. They are among the most common contagious diseases. More than 65 million Americans have an incurable STD. Each year‚ 15.3 million new cases are reported; half of these infections are lifelong
