It is more difficult to identify eukaryotic genes than prokaryotic genes because in eukaryotes ________.
A) the proteins are larger than in prokaryotes
B) the coding portions of genes are shorter than in prokaryotes
C) there are no start codons
D) there are introns

Question

Quizplus · Accepted Answer

Eukaryotic genes contain introns, non-coding regions that interrupt the coding sequence, which increases the difficulty of identifying the actual coding sequences. Prokaryotic genes do not have introns, making it easier to identify their coding regions. Choices A, B, and C are incorrect because they do not relate to the difficulty in identifying eukaryotic genes.
