Researchers have shown for the first time that non-coding parts of genes called introns can copy themselves and move around the genome. Nevertheless, these DNA sequences remain mysterious. Scientific ...

The sequences of nonsense DNA that interrupt genes could be far more important to the evolution of genomes than previously thought, according to researchers. Their study of the model organism Daphnia ...

Researchers at University of Tsukuba have decoded the nuclear genome of Amorphochlora amoebiformis, a unicellular marine alga belonging to the chlorarachniophyte group.

Figure 1: Structure and splicing pathways of group II introns. Second-step reversal (reverse splicing) is of great mechanistic interest because excised group II introns can behave as retroelements, ...

One of the most long-standing, fundamental mysteries of biology surrounds the poorly understood origins of introns. Introns are segments of noncoding DNA that must be removed from the genetic code ...
