Estrogen biosynthesis in the human body
By: Eileen Eva
Estrogen also œstrogens, Estrogens (AmE), or oestrogens (BE) is derived from Greek, estrus, and gen meaning sexual desire and generate respectively. It is responsible for several functions in the human body especially in females. In its natural form, estrogen occurs as estrone (E1) which...
Estradiol's role in the human body
By: Vilie Farah
Estradiol is a sexual hormone belonging to the group of estrogens. Estrogens themselves are classified in the group of steroid hormones – biologically active substances that form in the human body and that have one common predecessor – cholesterol.Estradiol’s concentration in the body...
Technologies and materials: Comparison of urethral and prostate stents
By: Alicia M Prater PhD
Stenting is a technique used to open closed ducts in the body. The urethra is the duct between the bladder and external environment. Expandable materials, or stents, are inserted into the urethra to aid in the flow of urine by opening the channel in the...
Astounding breakthrough: Scientists create synthetic proteins that sustain life
By: Terrence Aym
2010 ended as a year of astounding breakthroughs in virtually all the sciences. The science of biology led the way with one stupendous breakthrough and revelation after another. So fast a pace did the breakneck breakthroughs occur that often it seemed a day barely passed...

With all the scientific explanations of cloning, one would think that cloning is the next best thing since the coming of Christ! Human cloning is just another way to place man into that, “want to be God’ position and with this position isn’t...
How genetic engineering works
By: Tamara Haddock
Scientists preform genetic engineering any time they chance the natural occurring DNA of an organism. The oldest form of genetic engineering is selective breeding. While it is not changing an individual group of cells on the microscopic level, it is using the knowledge of how...

The cell is the basic unit of life. Inside a cell is a hereditary marker called DNA, or deoxyribonucleic acid. The DNA contains the sequence which has vital information on the genetic makeup of an organism. Genes are responsible of the traits inherited by a...
How genetic engineering works
By: Eileen Eva
Genetic engineering or genetic modification is a relatively new branch of science. Bacteria were the first to be genetically modified in 1973, followed by mice in 1974. Genetic engineering has seen a fair share of controversies from people who believe that it is playing God...
How genetic engineering works
By: Alicia M Prater PhD
Genetic engineering is a set of molecular biology techniques that aim at manipulating an organism’s DNA to achieve a particular aim. As Biology Online notes in its definition of the term, genetic engineering can be applied to a number of fields for a number...

As we understand genetics better the possibility of altering or engineering the genetics of ourselves or, more easily, our children, has moved out of the realm of science fiction into a real possibility. There are a number of different types of genetic engineering, from the...
