| 释义 | mRNA,Non-Polyadenylated《英文msh词典》mRNA,Non-Polyadenylated [同义词] mRNA,Non-Polyadenylated [主题词] RNA,Messenger [中文释义] mRNA,非多聚腺苷酸 [英文释义] RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end,referred to as the poly(A) tail. The function of this tail is not known for certain,but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm. |
