Scientists are beginning to learn how to use retroviral vectors in gene therapy. Vectors are agents that carry infections and transmit them, like mosquitoes or deer ticks. Retroviruses can be vectors when they infect human cells. That is, when they cause infection, they can carry...

Gene therapy is a brave new science that could change the face of history, and the grim fate of those born with crippling genetic diseases. It involves the manipulation of genes themselves, and as such, diseases that are caused by faulty or absent genes will...

Gene therapy is an emerging science which has enormous potential to cure genetic diseases such as cystic fibrosis, hemophilia A and many other disease states. It allows the scientists the ability to manipulate the genetic makeup of a patient using a virus which has been...

Like many other discoveries and inventions, Rosalind Franklin’s achievements are currently being implemented on a great variety of fields. Without her work, most of the new bio-technologies that are currently being developed would not have been researched on the first place. Her mayor importance...

Down syndrome is a genetic disorder caused by the presence of an extra copy of the twenty-first chromosome in the human genome. This condition, more properly called trisomy 21, causes severe mental and physical disabilities, and it occurs in about 1 in every 900 births...
What the human genome endeavor revealed about Parkinsonism
By: Effie Moore Salem
Parkinsonism is a progressive neurological disease process in humans. In its path it decreases dopamine and other cellular chemicals necessary for effective nerve health. Previously, or prior to the latest findings, Parkinsonism was thought to be environmental in origin since no genetic studies pointed to...

Alagille Syndrome is an inherited disorder that occurs in one out of every 70,000 births according to the National Digestive Diseases Information Clearinghouse. Usually, children receive a diagnosis before the age of three. Symptoms A common symptom of Alagille Syndrome is jaundice. As this...
Structure and genes of the HIV genome
By: Alicia M Prater PhD
Human immunodeficiency virus (HIV) is a retrovirus (lentivirus family). Its genome is made of RNA, instead of DNA like humans and other animals, or even like most other viruses. Inside each virus molecule are two identical strands of RNA and three enzymes necessary for viral...

In 2009, a panel of scientists headed by Kevin Weeks of the University of North Carolina managed to decode the full structure of the HIV-1 genome by means of a technique called SHAPE (selective 2'-hydroxyl acylation analyzed by primer extension). A report on the findings...
What twin studies have taught researchers about epigenetics
By: Janet Grischy
Identical twins begin from the same zygote, the same combination of egg and sperm. Therefore they have identical DNA, giving them the same genetic makeup. Yet identical twins do not remain identical throughout life. Because they don’t, researchers study the differences that monozygotic twins...
