For the first time, scientists have shown that a genetic element on one chromosome may direct gene activity on another chromosome. (hhmi.org)
A linkage test or direct gene test (like PFK - phosphofructokinase deficiency) would make control and carrier detection possible. (essfta.org)
The expression of specific genes in a particular root cell determine its fate — the zone in which it will function, Subramanian explained, so he is identifying which micro-RNAs direct gene expression to achieve this differentiation. (sciencedaily.com)
