The question “What is a gene?” has bothered geneticists for fifty years. Recent work with a small bacterial virus has shown how to split the gene and make detailed maps of its internal structure ...

Two new landmark studies show how a seeming tangle of DNA is actually organized into a structure that coordinates thousands ...

Computational prediction of gene structure is crucial for interpreting genomic sequences. But how do the algorithms involved work and how accurate are they? Expression-based systems that use only ...

A change from the normal order of bases leads to different types of gene mutation eg CGA / ACC / CGA. These mutations may change the activity of a protein if they occur within a gene. This might ...
