WebFeb 1, 2024 · These two DNA strands are called polynucleotides, as they are made of simpler monomer units called nucleotides. Each strand has a 5′end (with a phosphate group) and a 3′end (with a hydroxyl group). The strands are antiparallel, meaning that one strand runs in a 5′to 3′direction, while the other strand runs in a 3′ to 5′ direction. WebFeb 16, 2014 · The 5' and 3' mean "five prime" and "three prime", which indicate the carbon numbers in the DNA's sugar backbone.
