Even non-professionals may someday be able to create high-quality video panoramas using multiple cameras with the help of an algorithm developed by a team of Disney researchers.
DNA (deoxyribonucleic acid) is the main component of our genetic material. It is formed by combining four parts: A, C, G and T (adenine, cytosine, guanine and thymine), called bases of DNA combine in thousands of possible sequences to provide the genetic variability that enables the wealth of aspects and functions of living beings.
