An advantage of synthetic DNA over genomic or cDNA is the ability to
A) obtain genes that lack introns.
B) insert desired restriction sites into the DNA sequence.
C) make DNA from cellular RNA and the enzyme reverse transcriptase.
D) isolate unknown genes.
E) obtain genes that lack exons.

Question

Synthetic DNA can be intentionally designed with specific restriction sites included in the sequence, making it easier to manipulate in the lab compared to genomic or cDNA that do not have these sites. While synthetic DNA can also be used to obtain genes without introns or exons, this is not necessarily an advantage over genomic or cDNA, as actual functional genes likely have introns and exons. Synthetic DNA can also potentially be used to isolate unknown genes, but this would require specific design and screening methods. Reverse transcription can be used to make cDNA, but this is not a unique advantage of synthetic DNA.
