The ENCODE project revealed that as much as 75% of the genome in humans is actually transcribed into RNA. Most of this is non‒protein-coding RNA. Which of the following include two new classes of noncoding RNA discovered by the ENCODE project?

Question

Quizplus · Accepted Answer

The two new classes of noncoding RNA discovered by the ENCODE project are MicroRNA (miRNA) and Long Noncoding RNA (lncRNA). Therefore, option D is the correct choice. Option A includes mRNA and tRNA, which are not new classes of noncoding RNA. Option B includes rRNA and snRNA, which were already known before the ENCODE project. Option C includes Pre-mRNA and hnRNA, which are intermediate products in the process of mRNA synthesis and not considered as noncoding RNA.
