Class 12 NEET Biology Molecular Basis of Inheritance Questions Part 1

m RNA is not made directly in a eukaryotic cell. It is transcribed as heterogeneous nuclear RNA (hnRNA) in the nucleus. hnRNA contains introns and exons. The introns are removed by RNA splicing leaving behind the exons,which contain the information. The exonic regions of RNA are joined together to produce a single chain RNA required for functioning as translational template.
