2. The 5' to 3' direction of one strand runs counter to the 5' to 3' direction of the other strand.
3. Base pairings create unequal spacing between the two DNA strands.
4. One strand is positively charged and the other is negatively charged.
5. One strand contains only purines and the other contains only pyrimidinesWhat is meant by the description "antiparallel" regarding the strands that make up DNA?
The answer is 2.
The strands are parallel (equidistant apart), but one strand has the -OH (3') end up while the other has the Phosphate (5') end up, creating the anti- part of anti-parallel.What is meant by the description "antiparallel" regarding the strands that make up DNA?

What is meant by the description "antiparallel" regarding the strands that make up DNA?When you look at a particular end of the duplex the terminal nucleotide of one strand has a free 3'OH and the other has a free 5'PO4^2-. This makes the strands antiparallel and is because the specific direction of synthesis of DNA which is through 5'--%26gt;3' .
The fourth point in your question is wrong i guess. Both the strands are negatively charged due to the presence of phosphate groups.
Number 2
One strand runs 3' to 5' while the strand it pairs with runs 5' to 3'
