Cholesterol precursors in the human body
By: Alicia M Prater PhD
Cholesterol is an important molecule in the human body – it’s used to synthesize steroid hormones, such as estrogen, testosterone, and molecules that regulate inflammation, as well as vitamin D. Cholesterol is obtained from certain foods in the diet, but it is also synthesized...
How 99.9% of any one person's DNA is exactly the same as any other person regardless of ethnicity or race
By: Methane
In the early twentieth century many scientists held the view that biologically distinct races existed. The races corresponded to the major continental regions of Africa, Europe, Asia and the Americas. These races were distinguished from each other based on a few visible traits such as...
What are heterotrophs and autotrophs?
By: Tami Port MS
Nearly all food ultimately comes from the sun, and living organisms fall into one of two categories, based on specifically how they obtain that nutrition.* What Are Autotrophs? * Plants, and some forms of bacteria, are considered self-feeders. They are able to synthesize their...
Molecular biology techniques: RNA interference
By: daneemax
Just one decade after its discovery, RNAi technology has not only developed in leaps and bounds but also found its way into human gene therapies and eyed for by biotech companies worldwide in the promise of far-reaching therapeutic applications. This paper is about the progress...
What is a biological species?
By: Heather Lyon
Humans have a need to classify and simply information. One way we do this in biology is by naming and classifying all the organisms that have been discovered. A scientific name is given to all organisms so that they can be distinguished from one...
What is bioinformatics?
By: Wendy R.
Bioinformatics is a field of Science where Biology, Computer Science and Information Technology merge. A concern of Bioinformatics is the ability to quickly retrieve data, so that researchers can use each other's information to work towards a common goal. A well known use of bioinformatics...

What if the most important aspects of life were taken away? For example, imagine two ordinary human beings that are exactly alike at the beginning. One will grow up and have all of the rights and privileges a human gets in life. The other human...

Molecular dynamics uses approximations of known laws of physics to simulate the motion of atoms and macromolecules. The technique has been used to probe the function and action of many biological molecules, allowing researchers to test hypotheses to an unprecedented resolution. There are many types...

H-DNA as a Potential cis-Element Regulating Gene Expression Subhankar ChakrabortyDNA triplexes are formed when a polypurine segment of duplex DNA is recognized and bound by a single stranded oligonucleotide lodging in the major groove of the duplex. Such a single stranded oligonucleotide is termed as...
