Length of PolyA tail is different in two cells

Explanation:

  • Different lengths of Poly A tails are present for different mRNAs so when we compare two peptides translated in two different cells we have different lengths of PolyA tail
  • PolyA tail is basically a long chain of nucleotides(adenine nucleotides) which are added to messenger RNA(mRNA) during processing of RNA
  • It increases the stability of the molecule
  • It protects the mRNA molecule from undergoing degradation in the cytoplasm
  • It is involved in binding proteins which further initiates translation;introns are removed from pre mRNA before the final mRNA is exported into cytoplasm
