Comparison of gene expression in different human tissues using the nuclear run-on transcription assay illustrates that
A)differences in protein production are mainly due to post-transcriptional mechanisms.
B)few differences in protein production are detected between tissues.
C)differences in protein production are mainly due to differential gene transcription.
D)differences in protein production are not due to differential gene transcription.
E)few differences in RNA production are detected between different tissues; thus differential protein production is mainly due to post-transcriptional mechanisms.

The nuclear run-on transcription assay is designed to measure the rate of gene transcription in different conditions or tissues. When this assay shows differences in gene expression across various human tissues, it indicates that these differences are primarily due to differential gene transcription. This means that certain genes are being transcribed more actively in some tissues than in others, leading to variations in protein production based on the transcriptional activity.
