Several different globin genes are expressed in humans,but at different times in development.What mechanism could allow for this?
A)exon shuffling
B)intron activation
C)differential translation of mRNAs
D)differential gene regulation over time

Question

Quizplus · Accepted Answer

The differential gene regulation over time allows for the different globin genes to be expressed at different times in development. This could be due to changes in transcription factors, enhancers or repressors that affect the expression of these genes.
