Credit: Kateryna Kon/Science Photo Library/ What is DNA, and how does it work? You don't need a degree in genetics to understand. Here, we'll give an overview of DNA and answer questions ...

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 ...

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 ...
