How can just four nitrogenous bases--adenine, cytosine, guanine, and uracil--possibly code for all 20 amino acids? Thus, early researchers quickly determined that the smallest combination of As ...

The genetic code, a universal blueprint for life, governs how DNA and RNA sequences translate into proteins. While its complexity has inspired generations of scientists, its origins remain a topic ...

For decades, farmers have faced a trade-off between size and flavor when growing tomatoes and eggplants. The hefty tomatoes stacked in supermarkets today may be impressive in size, but many consumers ...

Scientists have shown that one portion of the petunia’s genetic code can direct the creation of molecules behind the plant’s ...

"Cracking Your Genetic Code" reveals that we stand on the verge of such a revolution. Meet a cancer patient who appears to have cheated death and a cystic fibrosis sufferer breathing easily ...

DNA molecules are large and complex. They carry the genetic code that determines the characteristics of a living organism. The diagram shows the relationship between the cell, its nucleus ...

DNA can be cut up and separated, which can form a 'bar code' that is different from one person to the next. A gene is a small section of DNA in a chromosome. Each gene codes for a particular ...
