TENSION.-Thesimple stress of tension tends to produce the strain of elongation.

By contrast, pituitary isografts were able to rescue the ductal elongation phenotype.

This stimulation required only the RNA polymerase II elongation complex and Hce1.

The potential role of PEPC in cotton fibre elongation is examined here.

Interestingly, the analogous residues in TFIIS are also critical for elongation activity.
