Maturation of mRNA from HnRNA | Plant Physiology
In this article we will discuss about the maturation of mRNA from HnRNA. In higher organisms, within the nucleus, heterogenous nuclear RNA (HnRNA) or high molecular weight RNA (HMW RNA) or DNA-like-RNA (dRNA) is synthesized. These molecules are larger than mRNA and used in cytoplasm. Polymerase-I is added at 3'-end of HnRNA. Subsequently mRNA molecule is released when HnRNA having [...]
