When a stem cell differentiates and changes in size and shape, specific genes are being EXPRESSED.

Gene expression involves the flow of genetic information from genes (DNA) to RNA and proteins.

Differentiation involves first the transcription of genes to messenger RNAs (mRNAs) and second the translation of these mRNAs to proteins.

During gene transcription, a fragment of DNA called 'gene' is used as a template to create an mRNA in the cell nucleus.

Subsequently, this mRNA travels to the cytoplasm where it is then used as template to create a protein by the process of translation.

In conclusion, when a stem cell differentiates and changes in size and shape, specific genes are being EXPRESSED.
