Human genomes contain several globin genes that are expressed at distinct times in development. Which of the mechanisms listed best explains this developmental pattern?
A) exon shuffling
B) pseudogene activation
C) differential translation of mRNAs
D) differential gene regulation over time

Question

Quizplus · Accepted Answer

Differential gene regulation over time is the mechanism that best explains the distinct expression of globin genes at different developmental stages. This involves the activation or repression of these genes in a temporal manner, allowing for the appropriate type of globin to be produced when needed during development.
