The answer is the base sequence of gene's promoter.
DNA is a two-stranded helix. One strand is called a template strand, the other one is called a coding strand. The template strand is copied into mRNA, and the coding strand is complementary to the template strand. RNA polymerase, an enzyme responsible for transcription, has to recognize the right strand before transcription begins. So, it recognizes one or more short sequences on the coding strand. This is the base sequence of gene's promoter. Thus, the complementary strand is the template strand.

<span>Angioplasty is the technique of mechanically widening narrowed or obstructed arteries. This is the process of putting a balloon in your arteries to widen it for blood flow. So Angioplasty would not be the best way to treat an aneurysm because an aneurysm is a bubble full of blood. Angioplasty would not work.</span>
