Polyadenylated
Polyadenylation
The process of adding a poly(A) tail to the 3' end of a messenger RNA (mRNA) molecule.In molecular biology, polyadenylation is a type of post-transcriptional modification that occurs in eukaryotic cells. After transcription of a gene, the initial RNA transcript undergoes processing and modification, which includes the addition of a poly(A) tail to the 3' end (three prime end) of the molecule.The poly(A) tail is a long sequence of adenine nucleotides, typically 50-250 adenines in length, which is added by a group of enzymes called poly(A) polymerases. The function of the poly(A) tail is to:1. Protect the mRNA from degradation: The poly(A) tail helps to prevent the mRNA from being degraded by exo-nucleases.2. Enhance translation: The poly(A) tail helps to recruit ribosomes to the mRNA, thereby increasing translation efficiency.3. Regulate mRNA stability: The length and structure of the poly(A) tail can influence the stability and export of the mRNA from the nucleus to the cytoplasm.Overall, polyadenylation is an essential step in the processing of mRNAs in eukaryotic cells.
