Several of the 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) pseudogene activation
D) differential translation of mRNAs
E) differential gene regulation over time

Question

Quizplus · Accepted Answer

Differential gene regulation over time allows for the expression of different globin genes at different times in development. This regulation can occur at the level of transcription, mRNA stability, translation, and protein stability. By regulating when and where genes are expressed, cells can control which proteins are present at specific developmental stages or in response to certain signals or stimuli.
