Note that because the two polynucleotides that make up double-stranded DNA are "upside down" relative to each other, their sugar-phosphate ends are anti-parallel, or arranged in opposite orientations.

DNA analysis is crucial for identifying individuals and their relatives, using technologies like PCR, electrophoresis, and ...

Double-stranded DNA is composed of two linear strands that run opposite to each other, known as anti-parallel strands; these strands twist together to form a double helix. The structure of DNA can ...
