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.

Explanation:

A. The differential induction of DNA transcription suggests the cells are destined to become different tissues.

Given the lack of RNA encoding, DNA transcription is not occurring. This may happen because the cells are destined to undergo different forms of differentiation- here, transcription would require the activation of different regions of the genetic code called transcripts.

Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
