'Rna localization' diaporamas de présentation

RNA localization

RNA localization. mRNA can be localized to subcellular compartments by actin or tubulin -dependent processes. Examples :. Xenopus : Vg1 mRNA (TGF b ) to vegetal pole. Drosophila : nanos, oskar mRNA (posterior) and bicoid (anterior). (requires mRNA binding protein staufen).
