By the early 1950s, scientists knew that genes were made of deoxyribonucleic acid (DNA) and that specific proteins were the products of specific genes. The exact link between DNA and proteins was less well understood, however. Since proteins are...

The genetic code is the set of correspondences between the nucleotide sequences of nucleic acids such as DNA (deoxyribonucleic acid), and the amino acid sequences of polypeptides. These correspondences enable the information encoded in the chemical...

The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA sequences) is translated into proteins (amino acid sequences) by living cells. Specifically, the code defines a mapping between tri-nucleotide sequences...

Security technology: Tiny DNA fragments can function as invisible embedded security tags IT HARDLY needs saying that the double helix of deoxyribonucleic acid--better known as DNA--is one of nature's most wondrous materials. Its twisting strands securely encode the genetic information on which...

A SECOND genetic code it is not. But a discovery announced last week does begin to clear up the biggest remaining mystery in the code of life. In all living things, the information encoded in genes has to be translated from the language...

These days, data get stored on disks, computer chips, hard drives and good old-fashioned paper. Scientists in Japan see something far smaller but more durable _ bacteria.The four characters that represent the genetic coding in DNA work much like digital data. Character combinations can stand...

More than a hundred species of tiny land-breeding frogs in the Caribbean evolved from a single South American species that probably hitched a ride on a raft of vegetation and washed up on an island beach, according to scientists who spent decades collecting tissues from...

Cracking the genetic code has had a big impact on learning and treating various genetic diseases. By knowing which genes are responsible for which functions, genes can be altered or treated so that a certain genetic disorder can be cured or at least made better.
