Describe double helix structure of $DNA$ and how are the sequences of other strand predicted.
If a double stranded $DNA$ has $20$ per cent of cytosine, calculate the per cent of adenine in the $DNA$.
Thirty percent of the bases in a sample of $DNA$ extracted from eukaryotic cells is adenine. What percentage of cytosine is present in this $DNA$ ?
