The 5' cap and ploy A tail at 3' end

Explanation:

A newly transcribed RNA in eukaryotic is termed as pre-mRNA. After the processing it becomes a fully mature mRNA.

During the processing capping and splicing is done as follows-

A 5' cap is added to the beginning of the newly formed pre-mRNA A 3' poly-A tail is added to the end of pre-mRNA. Introns are removed and exons are added together, this is splicing.

Thus, during processing, both the ends or pre-mRNA are modified by the addition of some chemicals. These additional chemical sections that are added to the 3' and 5' ends do not code for any amino acid.
