Antisense DNA

Antisense DNA
In double-stranded DNA, only one strand codes for the RNA that is translated into protein. The strand that does not do so is called the antisense strand. Another way of defining antisense DNA is that it is the strand of DNA that does not carry the information necessary to make proteins. DNA normally has two strands — the sense strand and the antisense strand. Although these strands are exact mirror images of one another, only the sense strand contains the information for making proteins. The antisense strand does not. Antisense DNA is also known as noncoding DNA.
