Which of the following clusters of terms accurately describes DNA as it is generally viewed to exist in prokaryotes and eukaryotes?
A) double-stranded, parallel, (A + T)/C + G) = variable, (A + G)/(C + T) = 1.0
B) double-stranded, antiparallel, (A + T)/C + G) = variable, (A + G)/(C+ T) = 1.0
C) single-stranded, antiparallel, (A + T)/C + G) = 1.0, (A + G)/(C + T) = 1.0
D) double-stranded, parallel, (A + T)/C + G) = 1.0, (A + G)/(C + T) = 1.0
E) double-stranded, antiparallel, (A + T)/C + G) = variable, (A + G)/(C + T) = variable

Question

DNA is generally double-stranded and antiparallel, meaning the strands run in opposite directions. The base pair composition is variable in terms of (A + T)/C + G), but the ratio of (A + G)/(C + T) is consistently around 1.0.
