In a Wild- Type Strain of Fruit Flies, the Length

question 78

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) The mRNA was prematurely degraded.
• C) There are introns in the DNA that were cut out of the mRNA.
• D) A mutation caused the formation of an extra stop codon in the gene.
