Some Segments of the Precursor MRNA in Eukaryotes are Non-Coding

Question

Some segments of the precursor mRNA in eukaryotes are non-coding and are called
A)exons.
B)introns.
C)integrans.
D)uselessans.

Accepted Answer

The segments of precursor mRNA that are not translated into protein are called introns. Exons are the segments that remain after the introns have been removed and are ultimately spliced together to form mature mRNA. Integrans and uselessans are not correct terms.
