Epigenetic silencing of tumor suppressor genes in cancers
By: Marc Saleme
Epigenetic silencing is a means by which cellular machinery may block certain genes in the DNA sequence from being expressed. Epigenetic silencing of tumor-supressor genes is a relatively ubiquitous cellular mistake which allows the unchecked proliferation of the cell, i.e. cancer. The recognition of...

Deoxyribonucleic acid or for short DNA, is the structure (also a nucleic acid) that based the foundation for all biological life on Earth. From complex mammals like humans to simple marine life such as terrotopsis (type of jellyfish that never dies). If we can harness...

Human cloning is dangerous to mankind when viral or other harmful components can be transferred, along with cloned tissue, into new hosts. That is the first area of concern, as cloning does not just involve snipping and clipping at the sub molecular level. The tissue...
An overview of human cloning
By: Elizabeth M Young
The excitement about cloning started when Scottish scientists at the Roslin Institute successfully cloned a sheep, and named the clone "Dolly". Since then, whatever works that the human imagination and access to resources can come up with have been flooding the airwaves, the movie screens...

Genetic screening is an issue that has heartbreaking reasons, heartbreaking ideas, and heavy political, racial and social consequences. On one side of the issue, prevention of passing on terrible genetic disorders to children is an important consideration that many couples want to know about before...
Causes of Down's Syndrome
By: Dr Pandula Siribaddana
Down's syndrome is a chromosomal abnormality that can be identified in approximately 1 in 1000 live births. The condition has shown to be associated with the increasing maternal age and the likelihood of giving birth to a baby with Down's syndrome rises steeply after the...
Genetics: What is Turner's Syndrome?
By: Dr Pandula Siribaddana
Turner syndrome is a chromosomal abnormality which is precipitated by the complete absence or incomplete nature of the X chromosome. The affected individuals would most likely be females as the underlying deficiency is in the X chromosome. The researchers have gathered that about 98% of...
Have Breakthroughs in Dna Research Led to more Harm than Good
By: Elizabeth M Young
Many of us are proof positive that the breakthroughs in DNA research have saved lives, identified undiagnosed conditions that cause long standing illness, suffering, decline, and death. Breakthroughs in the mapping of the human genome have led to genetic counseling, which allows couples to avoid...

Scientists have long been trying to track down the gene responsible for human intelligence. David Haussler, director of the center for Bio-molecular Science and Engineering at the University of California, Santa Cruz, and his team found strong but still circumstantial evidence that a certain gene...

Heredity is the transfer of specific traits and characteristics from parents to their offspring. Since Gregor Mendel's famous pea-plant experiments, we have come to understand genetic inheritance down to specific genes with immense accuracy. Some traits are as simple as a single gene passed from...
