Verified
A sequence of mRNA that is removed during processing is a(n)
A) exon.
B) intron.
C) replicon.
D) promoter.
E) gene.
mRNA
Messenger RNA, a type of RNA that conveys genetic information from DNA to the ribosome, where it specifies the amino acid sequence of the protein products of gene expression.
Intron
Intervening sequence found between exons in mRNA; removed by RNA processing before translation.
Exon
Segment of mRNA containing the protein-coding portion of a gene that remains within the mRNA after splicing has occurred.

Final Answer :
B
Explanation :
Introns are sequences of mRNA that are removed during the processing of the mRNA molecule. Exons, on the other hand, are sequences that remain in the final mRNA molecule and are ultimately translated into protein. Replicons refer to the DNA sequences that are replicated during cell division, promoters are DNA sequences that initiate transcription of a gene, and a gene is a segment of DNA that codes for a specific protein or RNA molecule.
