The official full name of the gene is neurofibromin 1 (NF1). The gene expresses normally in Homo sapiens; however, the expression has been discovered in orthologs such as a mouse and Drosophila melanogaster. As its molecular function, NF1 acts as a tumor suppressor gene. Tumor suppressors prevent the uneven and...

The marketing advertising industry has taken its share of hits for what many believe is its role in promoting the image of the perfect body. It has also been suggested that this constant bombardment is at the root of many eating disorders, particularly in teenage girls but even beyond that....

Deoxyribonucleic acid (DNA) is the hereditary material that is found in humans and other organisms. Each and every cell in a person’s body contains the same DNA. In most cases, DNA is typically located in the cell nucleus where it is referred to as nuclear DNA. Nevertheless, some DNA can...

There are many exposures, or teratogens, that can harm a human baby during its embryonic state. During this period of development, beginning at week 5 of pregnancy, critical structures are beginning to develop. Stem cells undergo the process of differentiation, taking on the properties and functions of the specific organs...

DNA is deoxyribonucleic acid. It is made up of four chemical bases: adenine, guanine, cytosine, and thymine. Each base has an attached sugar molecule and phosphate molecule, and this combination is called a nucleotide. The bases form pairs, with adenine pairing up with thymine and cytosine pairing up with guanine....
