Two cells (a and b) from an embryo in the first trimester of development were examined. the image on the left below shows a southern blot detecting for the presence of a segment of dna. the image on the right shows a northern blot detecting for the rna encoded by that segment of dna:
what is a logical conclusion based on this data?
a. the differential induction of dna transcription suggests the cells are destined to become different tissues.
b. the differential induction of dna transcription suggests the cells utilize the same activator sequence.
c. the lack of transcription of the dna in cell b indicates that cell b has stopped developing.
d. the lack of transcription of the dna in cell b indicates that cell b has undergone apoptosis.
