We previously showed in vivo that coding-end processing is specific for each coding end, suggesting that specific motifs in a coding-end sequence influence nucleotide deletion and P-region formation. Using colony formation in soft agar as a measure of full transformation, we report here that R- cells can be transformed by v-src, although they still cannot viagra be transformed by the activated c-src527 (mutation at tyrosine 527 to phenylalanine which. Learn how you can partner with. TEDx events, find and attend local, independently organized events.
