Which statement about the human genome is true?
A) In any given specialized cell type,most of the genome is being transcribed.
B) Most transcripts are cell-type specific.
C) Most transposons are active most of the time.
D) Noncoding RNAs seldom,if ever,perform regulatory roles.
E) Both a and b

Question

Quizplus · Accepted Answer

While some portions of the genome may be transcribed in any given specialized cell type, the majority of the genome is not actively transcribed. Additionally, many transcripts are not cell-type specific and are expressed in multiple cell types. Transposons are generally not active, and noncoding RNAs can have important regulatory roles. Therefore, choice B is the most accurate statement about the human genome.
