Gene expression profiles differ from classic gene maps in that
A) gene expression profiles depict the relative locations of genes on chromosomes, and classic gene maps show the increase and decrease of transcription with time or in different tissues.
B) gene expression profiles depict the increase and decrease of transcription with time or in different tissues, and classic gene maps show the relative locations of genes on chromosomes.
C) gene expression profiles measure DNA and classic gene maps size-order the chromosomes.
D) gene expression profiles sequence genomes whereas classic gene maps do not actually sequence the DNA.
E) gene expression profiles have not yet been done in humans but classic gene maps have.

Question

Quizplus · Accepted Answer

Gene expression profiles depict the increase and decrease of transcription with time or in different tissues, while classic gene maps show the relative locations of genes on chromosomes. Therefore, option B is correct. Option A is incorrect because it describes classic gene maps instead of gene expression profiles. Option C and D are incorrect because they are not accurate descriptions of gene expression profiles or classic gene maps. Option E is incorrect because gene expression profiles have been done in humans.
