Answer:
Intron is essential for coding of proteins and hence it is present in the mRNA of Eukaryotes
Step-by-step explanation:
Intron are important for coding proteins. In eukaryotic cell, the mRNA has introns and these introns are removed by encoding proteins from mRNA with a right sequence. Thus, introns are essential to encode DNA, RNA, protein etc, and they take partly important roles during encoding of mRNA to higher forms of molecules.
