Given the antiparallel orientation of the two strands that make up duplex DNA, it is reasonable to expect that some helicases unwind DNA in a 5′→3′ direction, while others unwind DNA in a 3 ...

The twisting ladder of the double helix is formed by combining (or hybridizing) two antiparallel DNA strands, which are held together by hydrogen bonds between the complementary bases: adenine to ...

They catalyze the addition of nucleotides onto existing DNA strands. ... Their pairing is also referred to as antiparallel. DNA polymerase synthesizes only in a 5′ to 3′ direction.

Complementary Base-Pairing. The two DNA strands in the double helix run in opposite directions (antiparallel to each other) to help the bases in each base pair fit into the double helix.

It has been proposed that isoforms of Drosophila mod(mdg4) result from the trans-splicing of independent mRNA transcripts derived from both anti-parallel DNA strands. In the August 14 Proceedings of ...

DNA is shown schematically, except for the part solved by cryo-EM where the two antiparallel DNA strands are orange and light yellow, respectively. Cryo-EM maps produced by Markel Martínez-Carranza.
