Several of the different globin genes areexpressed in humans , but at different times in development. Whatmechanism could allow for this: A) differential translation of mRNA B) exon shuffling C) intron activation D) pseudogene activation E) differential gene regulation over time Several of the different globin genes areexpressed in humans , but at different times in development.

Explanation / Answer
A) differentialtranslation of m-RNA. The expression ofdifferent globin genes in humans at different times of developmentis due to the differential translation of m-RNA. This is because dependingon the region and the requirement of the cell ;m-RNA istranslated. For instance myoglobin isexpressed only in the muscles but not in all the organs.
