A geneticist isolates a gene for a specific traits under study, she also isolate the corresponding $mRNA$. Upon comparison, the $mRNA$ is found to contain $1,000$ fewer bases than the $DNA$ sequence. Did the geneticist isolate the wrong $DNA$?

Yes, $mRNA$ is made from a $DNA$ template and should be the same length as the gene sequence.

Yes, the $mRNA$ should contain more bases than the $DNA$ sequence because bases flanking the gene are also transcribed.

No, the final $mRNA$ contains only exons, the introns were removed.

No, the $mRNA$ was partially degraded after it was transcribed.

Solution

The $mRNA$ formed after transcription of a gene is shorter than the $DNA$ because the intervening sequences called introns are removed through splicing.
