In chromosomal crossover, genetic exchange increases variation because the genes recombine to form another gene that is new. Only during phase 1 of meiosis, can the similar traits of the chromosome unite, making a variation. The farther apart the common traits of the chromosome are...
Effects of trisomy 13: Patau syndrome
By: Imonikhe Ahimie
Trisomy 13, also known as Patau syndrome or trisomy D, is a genetic disorder where the patient has 3 copies of the chromosome number 13 rather the usual 2 copies that most people have. The syndrome has been observed as far back as 1657 (Thomas...

When bleeding occurs (internally or externally), the body relies on a chain reaction of events known as the clotting cascade to signal the appropriate key players to stop that bleeding. It is a very specific game of dominoes, with each protein signaling the next on...
Cloning and Ethics Human Cloning Inevitable Cloning and Issues of Moral Ethics Animal Suffering
By: Christyl Rivers
There is not a slippery slope, as humans at present, do not value animals as they should. However, Animals should not be cloned for several reasons. Already on earth there are far too many human companion animals, and millions suffer from neglect and indifference. Also...

The mapping of the human genome in 2003, through The Human Genome Project, is one of the most important medical discoveries of all times. The human genome, in conjunction with cancer genomics, is presently being studied by researchers. As reported by the American Cancer Institute...
Are personalities determined by genetics or chance?
By: John D Carmack
The old debate of nature vs nurture continues to rage on today. While the pendulum has swung back and forth between the two, there are studies that show strong correlations of personality traits within families. However, it is not a 100% correlation, so that leaves...
Forensic test predicts hair and eye color from DNA
By: Sun Meilan
The analysis of human DNA has been progressing quickly over the past few years, allowing forensic experts to match a criminal’s DNA with forensic matter found at the scene of a crime. Called genetic profiling, its only issue is that it either relies on...

Protein synthesis is an essential function of unicellular and multicellular organisms alike. Enzymes, cell organelles, muscles, and bone matrix are all composed of proteins. For many years, biologists have known that proteins are composed of chains of amino acids linked together by peptide bonds. Prior...

The traditional central dogma of molecular biology is that protein-coding gene or DNA is transcribed into messenger RNA (mRNA), which is then translated into protein. Proteins then play their role in structure and function in the physiology of the human body. However, the completion of...

Gene therapy can be simply defined as a therapeutic technique which alters the genetic constituency of a cell in order to treat a specific disease. The concept was first introduced as early as 1972, although it was only in the year1990 that the FDA granted...
