Noncoding DNA, also known as "junk DNA" describes portions of the DNA sequence that do not appear to have any presentable use -- they do not encode for proteins, etc. In fact, in a most eukaryote cells, a rather large percentage of the total genome Continue Reading...
Each of these consultative bodies is made up of ten to fifteen doctors and scientists with widespread knowledge about infectious illnesses, immunology and vaccine research. The statistics measured by these groups are wider than that looked at by the Continue Reading...
What the Tick? Tick Born Diseases in America Introduction Part predator, part parasite, the tick is considered by many as America’s most harmful bug. Living in humid and overgrown areas, these critters make rural America more prone to acquiri Continue Reading...
Norovirus Etiology, Epidemiology, And Prevention Norovirus Acute gastroenteritis (diarrhea) can be caused by viruses, bacteria, and parasites, but in the United States the most common cause is the norovirus (CDC, 2012b). The norovirus contributes t Continue Reading...

Some of the illnesses linked with AIDS can be prevented or cured through other treatments ("What is the difference" par, 5). Symptoms of HIV / AIDS: Depending on the phase of the infection, the symptoms of HIV and AIDS vary. In early HIV infection Continue Reading...
There are many bacteria that are able to resist against antibiotic drugs, including penicillin. The resistance to antibiotics often occurs because not all bacteria that are part of the same species are alike. These small differences that exist amon Continue Reading...
