What is the non coding segments of a gene are cut out of an amrna transcript while are spliced?

Answer 1

Introns, exons

Answer 2

The non-coding segments of a gene that are removed from an mRNA transcript during splicing are called introns. The remaining segments, which are the coding regions, are called exons. Splicing is an important process that ensures that the final mRNA transcript contains only the necessary information for protein synthesis.
