Accumulating evidence suggests that new genes can arise spontaneously from previously non-coding DNA instead of through the gradual mutation of established genes. Bioinformaticians at the University of Münster (Germany) ...

Genetic information is stored in DNA and transcribed as mRNA. The mRNA is usually translated into proteins. However, it has long been known that mRNA can also be reverse transcribed to DNA and integrated back into the genome. ...

Many genetic and breeding studies have shown that point mutations and indels (insertions and deletions) can alter elite traits in crop plants. Although nuclease-initiated homology-directed repair (HDR) can generate such changes, ...
