What is hnRNA?

Understand the Problem

The question is asking about the definition or explanation of 'hnRNA' which refers to heterogeneous nuclear RNA, a type of RNA found in the nucleus of eukaryotic cells.

Answer

Heterogeneous nuclear RNA (hnRNA) is an immature single strand of mRNA.

Heterogeneous nuclear RNA (hnRNA) is an immature single strand of messenger ribonucleic acid (mRNA) that is synthesized in the nucleus and undergoes processing to become mature mRNA.

Answer for screen readers

Heterogeneous nuclear RNA (hnRNA) is an immature single strand of messenger ribonucleic acid (mRNA) that is synthesized in the nucleus and undergoes processing to become mature mRNA.

More Information

Heterogeneous nuclear RNA (hnRNA) is also called precursor mRNA (pre-mRNA). It includes both coding sequences (exons) and non-coding sequences (introns), which are modified during RNA processing to produce mature mRNA.

Tips

Confusing hnRNA with mature mRNA as they differ by the presence of introns and the processing stages they go through.
