Often it is desirable to express eukaryotic genes in prokaryotic cells.

The second formulation can be used for identifying differentially expressed genes from different types of sample.

They divided, generated energy, "communicated" with one another, produced proteins, expressed and regulated genes.

An analysis of the cerebellum-amygdala comparisons with these criteria yielded 230 differentially expressed genes.

First, we looked for differentially expressed genes (wild type vs mutant) at each individual time point.

This analysis resulted in the identification of 402 differentially expressed genes.

Recent advances in gene manipulation have made it possible to express foreign genes in heterologous systems.

Several abundantly expressed genes are also horizontal gene transfer candidates (see below).

Transgenic organisms are able to express foreign genes because the genetic code is similar for all organisms.
