DNA=antiparallel, RNA=parallel

Detailed explanation-1: -The thing that is not a difference is C. So DNA and RNA are both made up of nucleotides. Nucleotides. It’s something like this as a phosphate group.
Detailed explanation-2: -In nature, DNA and RNA exist in an antiparallel orientation, stabilized by Watson-Crick base pairs. However, in some cases, nucleic acid fragments with specific nucleotide sequences can adopt a parallel orientation involving non-canonical base pairing.
Detailed explanation-3: -So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.
Detailed explanation-4: -The strands of a DNA double helix are said to be “antiparallel” because the have the same chemical structure, but are opposite in direction.
