Daniela Teixeira is a molecular biologist whose published research investigated P-body assembly and the relationship between messenger RNA organization and biological translation. She was first author of a2005 study with Roy Parker's group showing that yeast P-bodies depend on RNA for their assembly and contain nontranslating messages.[ref]

The study combined cellular observations with experiments on enriched P-body preparations. Digestion with a ribonuclease disrupted the preparations, testing whether RNA contributed to their integrity. In cells, perturbing translation initiation and trapping messages in polysomes produced contrasting P-body responses. Those comparisons distinguished effects on RNA availability from the vague statement that translation had been inhibited.[ref]

An original image-analysis example illustrates a limit of such observations. Suppose a hypothetical cell contains ten visible foci with four arbitrary fluorescence units each, while a second condition contains five foci with eight units each. Both have40 units assigned to the foci. Counting foci alone would miss that equivalence; conversely, equal total signal would not establish identical molecular composition or RNA decay activity. The numbers are stipulated, not measurements from Teixeira's paper.
