Answer:
The correct answer is option E) "The presence of one or more introns".
Explanation:
Introns are non coding sequences located within genetic sequences that are removed during RNA maturation by a process known as RNA splicing. A gene that has 2000 nucleotide pairs but is translated into a mRNA molecule with 1200 nucleotides most likely have one or more introns that in conjunction are of 800 nucleotides in size. Once the intros are removed from the mRNA molecule the coding sequence is ready to be translated into a protein.
