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...
There are about 6 billion nucleotide letters of a particular sequence in a human cell. The full set is known as the genome. DNA information is found in units called genes. One gene codes roughly for one protein. The proteins perform most of the func Continue Reading...

HIV Human Immunodeficiency Virus (HIV) is a virus that attacks the immune system causing the individual to be at risk for opportunity infections, or infections that come about because the immune system is weak. It is a slow progressive disease that Continue Reading...
The Golgi receives new proteins and lipids from the ER, finishes them up, addresses them and sends them to their final destination. In this way, the Golgi could be the postal service of the city. Lysosomes get rid of unusable waste within the cell a Continue Reading...
In one laboratory experiment, bacteria exposed to high levels of pathogenic bacteria over several hundred generations eventually adapted "their progeny became dependent on having the formerly pathogenic bacteria in food vacuoles...(Jeon, 1991)" (Arm Continue Reading...
