The noncoding segments of nucleic acids that lie between coding regions are referred to as introns.

Explanation:

In the context of molecular biology, genes are typically made up of coding sequences called exons, which are the parts of a gene that are expressed to produce proteins. However, not all segments of a gene encode for proteins; the noncoding regions that separate these coding sequences are called introns. When a gene is transcribed into messenger RNA (mRNA), introns are transcribed along with exons. During the RNA splicing process, introns are removed, and the remaining exons are joined together to form a continuous coding sequence that can be translated into a protein.

Thus, the correct answer is introns.
