Question
Which of the following best defines the mid-blastula transition (or maternal-to-zygotic transition)?
time in development when genes begin to be transcribed from the embryonic genome
point in development when the primary axes become permanently established
developmental time point when an organism stops being a zygote and becomes a blastula
defines the time in which cell movements create invaginations to start placing the germ layers in order
E. developmental time point when translation is initiated
A.time in development when genes begin to be transcribed from the embryonic genome
B.point in development when the primary axes become permanently established

D.defines the time in which cell movements create invaginations to start placing the germ layers in order
E. developmental time point when translation is initiated
Explanation / Answer
A. time in development when genes begin to be transcribed from the embryonic genome.
Maternal to zygotic transition in the stage in embryonic development when the zygotic genome has exclusive control over development.
