Problem 1
How are "complementary bases" and "antiparallel strands" involved in the structure of DNA?
3 step solution
Problem 2
Shown here is the sequence of bases, in the \(5^{\prime}\) to \(3^{\prime}\) direction, in one strand of a hypothetical DNA molecule. Identify the sequence of bases in the complementary strand. $$ \begin{aligned} &5^{\prime}-\mathrm{A}-\mathrm{A}-\mathrm{G}-\mathrm{T}-\mathrm{T}-\mathrm{T}-\mathrm{G}-\mathrm{G}-\mathrm{T}-\mathrm{T}-\mathrm{A}-\mathrm{C}-\mathrm{T}-\mathrm{T}-\mathrm{G}-3^{\prime} \\\ &3^{\prime}---------------4-5^{\prime} \end{aligned} $$
