WebThe DNA strands ran in opposite directions. As of 2024, Watson and Crick´s proposed DNA structure has remained the verified structure with a few variations of B-Form DNA, the major form of DNA in living cells. Later, in May 1953, Watson and Crick proposed a replication mechanism for DNA using their DNA structure.
