Which sections in mature rna do not code for amino acids?

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-

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.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
