Gene expression explained
By: John Traveler
DNA is an alphabet soup of four amino acids Adenine (A), Guanine (G), Cytosine (C), and Thymine (T), seemingly strung out in a sequence millions of nucleotides long (AGGCGGAAGGTTCTATCG.....). DNA is also referred to as the "blue print of life," inferring that all...
How DNA analysis helps to solve crime
By: Carolyn Teasley
DNA analysis has opened new doors in solving crimes. Deoxyribonucleic acid (DNA) has been analyzed to prove innocence or guilt of suspects of crimes with great accuracy. The use of DNA analysis can be performed one of two ways to solve crimes. In specific cases...

Without knowing precisely what genes were, working mostly alone with humble plants in a monastery garden, Gregor Mendel formulated his laws of inheritance. Essentially, he created the science of genetics. Mendel used thousands pea plants for his experiments, as he tried to discover what caused...
The process of DNA replication explained
By: John Traveler
The replication of the DNA molecule, is a process which lies at the very heart of life it self. The process is known as mitosis and involves the separation of the DNA in a cell to become two unique instances of the same thing. The...
Understanding DNA structure
By: John Traveler
The Deoxyribose Nucleic Acid (DNA) molecule is one of the most complex chemical constructs in the universe, and yet its structure is relatively simple to understand. The basic form of the DNA molecule is a double helix, often compared in configuration to a spiral staircase...
How genetic mutation can aversely affect living creatures
By: John Traveler
Genetic mutations are a part of life. Without them, there would be no life, because when incipient forms of DNA copied themselves the resulting two copies would always have been exact replicas of each other. Therefore DNA would never have evolved all the varieties we...
How dominant inheritance affects the passing on of certain genes
By: Carolyn Teasley
How Dominant Inheritance Affects the Passing on of Certain GenesGenetics is the scientific study of heredity, the process in which a parent passes genes to their children. This includes hair, skin and eye colors. Other characteristics that are affected are mental abilities, natural talents and...

Developments in the modern science continue to create new ethical dilemmas and bring up new questions: prompt us to redefine what exactly human beings are, what does it mean to be alive, how far we can go in an attempt to explore and influence so...
Sociopolitical Rammifications of Dnagenetic Research
By: Kente Bates
I say it has- not for the empirical evidence and the great things that come from them, it's the sociopolitical impact and how governments worldwide tend to use them. The fact that we have a 35-year debate over abortion, is proof. The pro-choice crowd uses...

TOSSING DICEWhen I take into consideration the word, "ethical", then I must admit that it might seem ethical to use DNA analysis to create super-humans. It might just make a super human world. Where fewer mistakes are made. Fewer doctors making mistakes on patients. Scientists...
