The exon is cut from the original mRNA sequence, leaving the intron as the portion of mRNA that leaves the nucleus to be translated into a protein. The exon is cut from the original mRNA sequence, leaving the intron as the portion of mRNA that leaves the nucleus to be translated into a protein. True False

Answer: false

Explanation:

The statement above is false.

The reverse of the statement above is the case. Removal of Introns and Splicing of exons are one of the post transcriptional processes.

The original mRNA transcript contains exons and introns. Exons are the coding region while Introns are the non-coding region. Because exons are the coding region of the DNA or RNA, because the code for specific amino acids they are highly conserved.

Introns are cut away from the exons by snRNPs, and the exons are spliced together to produce the translatable mature mRNA.
