Multiple Choice
In a wild-type strain of fruit flies, the length of a gene from the start to the stop codon is 2,000 DNA bases. Suppose an experiment indicated that the mRNA molecule transcribed from this gene is much shorter (only 1,200 bases) . What is the most likely explanation for this?
A) The first 800 bases of DNA are always cut out as it is transcribed into mRNA.
B) A mutation caused the formation of an extra stop codon in the gene.
C) There are introns in the DNA that were cut out of the mRNA.
D) The mRNA was prematurely degraded.
