Which of the following is NOT … WebIntrons are actually noncoding DNA segments (in other words, they do not code for proteins), so splicing them out actually helps produce a functional protein rather than potentially disrupt protein function. However, this doesn't mean introns are useless either; in fact, they are actually very important for regulating gene expression.
