In an organism such as a sea urchin, administration of actinomycin D prevents all mRNA synthesis. However, early development up to gastrula formation can take place in the presence of actinomycin D but gastrulation cannot. This implies that ________.
◦ development beyond gastrulation requires actinomycin D
◦ actinomycin D is part of the normal environment of a sea urchin and serves as a developmental signal molecule
◦ mRNA synthesis is not required after gastrulation
◦ maternal effect genes regulate development until gastrulation
◦ immature sea urchin embryos produce actinomycin D to regulate further development
