The section of a mature RNA which does not code for any amino acid is THE 5 PRIME CAP AND THE POLY A TAIL AT THE 3 PRIME END; THEY PART OF MATURE RNA AND THEY DO NOT CODE FOR AMINO ACIDS. 
Neither the 5 prime cap nor the poly A tail of RNA is transcribed during transcription.

The 5’cap and the poly(A)tail at the3’end are part of mature RNA do not code for an amino acid.

Further Explanation:

RNA is Ribonucleic Acid different from DNA by one ribose and RNA is single-stranded.

Types of RNA:

  • mRNA
  • tRNA
  • rRNA
  • SnRNA
  • SiRNA

Function of RNA:

  • Carries information from DNA to a ribosome  
  • Transmit genetic information
  • Play a role in splicing
  • Assemble protein

In TRANSLATION processes mRNA is converted to protein,but to translate mRNA it go under many processing before translating into protein mainly in eukaryotes.

  • 5’Capping: In capping 7’methylguanosine is added to 5’end of the transcription result by joining 5’to 5’phosphate.Capping is done only to protect nascent mRNA from degradation and help in initiating translation,does not code for any amino acid.
  • 3’poly A tail:100-260 residue of adenine nucleotide added   to the 3’end of mRNA to maintain the stability of mRNA,firstly,3’end of mRNA is cleaved and make free 3’OH,then polymerase enzyme attached adenine nucleotide to mRNA,poly A tail help in transport of mRNA from nucleus to cytoplasm for translation,they do not code for amino acid.
