alleryIntrons are best described as
Acoding regions of a eukaryotic gene
Bfragments of mRNA that code for the signal peptide
Cthe same as exons in prokaryotes
Dnon-coding regions removed by splicing
Answer & Solution
Correct answer: D. non-coding regions removed by splicing
Introns are intervening, non-coding sequences inside a eukaryotic gene.
Both introns and exons are transcribed into the primary RNA (hnRNA)
splicing then removes the introns and joins the exons before the mature mRNA exits the nucleus.
