Vedclass · Answer

(A) In eukaryotes,the primary transcript (pre-$mRNA$) contains both coding sequences called exons and non-coding sequences called introns.During the process of post-transcriptional modification,specifically splicing,the introns are removed,and the exons are joined together in a defined order.Therefore,the mature $mRNA$ consists only of exons,which are translated into proteins.

Which of the following is correct for $m-RNA$ in eukaryotes?
