REFLECT AND APPLY List three molecular changes that take place in the processing of eukaryotic mRNA.

Expert Solution
Interpretation Introduction

Interpretation:

The three molecular changes that take place in the processing of eukaryotic mRNA are to be listed.

Concept information:

miRNAs are the nucleotide stretches that affect the expression of genes and also help in the process of growth and development.

RNA is one of the two major genetic materials present in the living and nonliving (such as viruses) systems apart from DNA.

Explanation of Solution

There are three main molecular changes that occur in eukaryotic mRNA processing before it undergoes the process of translation. The noncoding sequences present in the transcript are sliced out from the mixture of both coding and noncoding sequences, leaving behind the coding ones together with the help of a process known as splicing. There is an addition of a stretch of adenine at the 3' end of the transcript, which is known as the poly-A-tailing
