Question

Transcribed regions present in the mature mRNA would arise from a ________ while transcribed regions NOT present in the mature mRNA would arise from a _______.

a. stop codon; initiation codon
b. anticodon; codon
c. intron; exon
d. exon; intron
e. initiation codon; stop codon

Answer 1

The mature mRNA transcribed from eukaryotic cells contains exons, which are coding sequences that code for proteins. The introns, which are non-coding sequences, are not present in the mature mRNA.

Step-by-step explanation:

In eukaryotic cells, the transcribed regions present in the mature mRNA arise from exons, while the transcribed regions NOT present in the mature mRNA arise from introns.
