Answer :
When a stem cell differentiates and changes in length and form, unique genes are being EXPRESSED.
Gene expression entails the drift of genetic data from genes (DNA) to RNA and proteins.
Differentiation includes first the transcription of genes to messenger RNAs (mRNAs) and second the translation of these mRNAs to proteins.
All through gene transcription, a fraction of DNA called 'gene' is used as a template to create an mRNA within the cellular nucleus.
Ultimately, this mRNA travels to the cytoplasm wherein it is then used as a template to create a protein via the technique of translation.
In conclusion, while a stem cell differentiates and changes in length and form, precise genes are being EXPRESSED.
Stem cell differentiation involves the changing of cellular to a greater specialized mobile kind, involving a transfer from proliferation to specialization. This involves a succession of alterations in cell morphology, membrane capability, metabolic pastime, and signal responsiveness.
